NickT - 2008 Subaru Liberty 2.5i NA 5MT ADM - Tuning

http://www.xtremeracingtuning.com/forum ... f=40&t=429
From the driving I have done, its fantastic. Its always had that dead spot below 3500 rpm, you push the throttle and it takes ages for the car to catch up. I always felt like the throttle was a second or so behind what I wanted. I installed a lightweight crank pulley to get a better throttle response and it worked but its nothing comparred to what you have done.

As soon as I even think about touch the throttle the whole car surges, I actually remember getting my head thrown back because I wasn't ready for how immediate it is! It has made the car so so SO much better to drive and that second or so of lag time is gone.

It really took some time to get used to it. Useually I sat there jamming my foot through the floor trying to get the thing to go forward under 3000rpm, it almost felt like the engine was lagging or choking until you built the revs up (even if you gently squeezed the throttle on). Now its completely different, the slightest touch and it just takes off!! It's also made gear changing much better. Shifting up, the sharper throttle makes it so easy shift fast and keep the power on. I can't really explain how but it felt so much easier with every gear shift to get the perfect amount of power to surge into the next gear without working the clutch to death. Heel-and-toe is a heap easier on the downshift.

Through the higher RPM I didn't really notice anything...until I got to a stretch of road I drive along pretty much every single time the testosterone surges lol. I have driven on this road a hundred times in this car, I have every apex down to a fine art, late braking and right at the limit because the road surface is perfect and there's no-one for miles. I went for a run and damn near killed myself!! The extra speed I was getting every time I put my foot down completely threw me off and I started to realise what you had done to it!!

The engine just revs so freely, it doesn't have that sluggish, delayed feel anymore. Even in the high RPM it's just that little bit quicker (although I would LOVE to extend the redline just a little tiny bit further :D ) As soon as I touch the throttle the RPM snaps up and its away and I was picking up so much more speed!! It's almost like you've found the SPORT button and switched it on. It reminds me more of my friends car, a BMW coupe with a 2.5l turbo engine (automatic). It was a fantastic car simply because you'd touch the throttle and the car would respond instantly, and now the Liberty is a similar story. Even when I get lazy and jump off the throttle, the engine bounces almost as if it's saying "hey!! a little smoother next time!!" lol

I couldn't care less if the graphs show a 1kw increase because the driving experiance is so much better. In my opinion, the quicker a car responds to your commands the closer the connection feels and hence, the driving experiance is better. You have made the car so that it doesnt matter what I'm doing: high speed, low speed, high rpm, low rpm...all I do is flex my big toe and the car responds instanty...and I love it!!! :D

Cheers,
Nick
v0 - I really noticed the change in throttle, it was by far the single biggest improvement to the car. v0 completely changed and sharpened the throttle response and brought so much extra power to the lower rpm region. It made the car react so much faster when going on and off the throttle, expecially in that dead spot under ~3500rpm. This brought the car to life!!!! That delay in the throttle is gone and it feels so eager to get down to business. Gear shifting is much better. Sharper throttle makes it easier to hammer up the gears and much easier to heel-and-toe.

v1 - This was when I noticed some extra mid range power. It felt like it was pulling through 3rd gear much better, especially between ~3500-5500rpm. It was almost the same right down low and right up high but it definitely felt like it was accelerating faster through the mid range.

v2 - With the first two roms really bringing out the power in the low to mid range rpm, I felt this rom affected the high range more then anything. It's really hard for me to describe exactly what I feel as most of my motor vehicle experiance is with bikes.

v3 - Most noticible thing is the new rev limit. I don't useually force the valves of my car dance on the bonet but I must admit, having the engine wind out to 7000rpm is more exciting then excitement itself!! lol. It's there if I need it, and now it means I can hit 100km/hr in 2nd gear instead of needing to shift to 3rd. Knocked over a second of its 0-100 time!!! No real change in the low-mid range but definitely a lot more fun in the higher rpm :D

v4 - Scary times!! lol Rev limit pushed even further to 7200...I had to beg for my engine's forgivness after the 3rd gear pull to limit. I was driving back home through a windy section of road and it was actually getting a bit tail happy!!!! The road was damp but still the AWD system useually plays it safe and it's stupendously difficult to get the tail out. Now with v4 installed, I really had to watch putting the power down out of some of the corners because I could feel it stepping to the side. Also gear changing when powering out of the long corners meant being more careful because the sharper throttle really puts the power down on every up shift.

All in all I absolutely love your work Edward, its truly amazing how much this tune has changed my car. So so so so SO many people said "don't bother with the NA engine, because the factory tune is pretty well perfect bla bla bla..." I say to those people: you are STUPID IDIOTS!!!! The factory tune is NOTHING!!! It is absolute crap comparred to how my car is now performing. I went back to stock tune the other day and it truly honestly felt as if I had just got out of my MY08 Subaru Liberty and into a 1997 Ford Laser. First thing I did was stall, second thing I did was get bored lol.

For anyone that is a true motoring enthusiast and that has an NA engine, I would reccomend them to you because no-one can argue with the results you get! :)

Cheers
Nick
Please find attached the 3rd gear pulls and driving logs for v5. I couldn't feel too much difference between v4 and v5 except in the high rpm range. Through the low to mid range I didn't notice anything but up in the higher rpm, expecially when I was just driving how I normally do, I noticed that the revs just felt like they were climbing faster. When I got to around 5000rpm I noticed it just felt quicker to get up to 6500 and it really feels agressive when I jump on the power. The whole car wobbles going on and off the power...time for suspension upgrade lol.

Its just so much more exciting!!! I can't say it enough! I jump on the throttle and it feels like I've just stood on a land mine lol. It immediately responds so it FEELS more powerful.

Cheers,
Nick

Hey Edward,

Thanks so much for v6!! Can't wait to try it out and see how it goes :) I read the reviews that were posted and I wish I had seen what this guy had written ages ago. I have found he really explains things very well and I agree with him about nearly all topics. I wish I had been able to write better reviews for you to go by.

After all the hard work you have put in, I will try to get you some better logs and better reviews to go by.

I have been watching the graphs but they are meaningless in my opinion. The graphs could show a 10kw gain or a 10kw LOSS and you know what? I DONT CARE!!! lol. Regardless of power and torque, you have completely transformed my car into such an exciting animal!! I really got to know v5 on the drive down and its incredable.

Through the mountains I was getting so much response from so little power! It like the hills don't bother it as much, it seems to be less affected by a sudden incline. Also I have noticed a really good fuel economy as well! I admit I am completely useless when it comes to reviews, but below are some of the comments that I really agreed with and found usefull to explain more how the car feels:

""On the stock ROM if you put your foot down flat to the floor, the tach very slowly starts to raise but the speedo doesn't really budge for another 3-5 seconds. Now I can put in less than 50% throttle and the car will pick up 5kph in about 2.5 seconds in 4th gear from 2000rpm. ""

""In sensible gearing, the car picks up very quickly now. It's easy to hoon around and get to 100kph without even getting close to getting flat to the floor. of course power-runs will still require you to go flat-foot, but the majority of the power is delivered at the top of the pedal now, and I like it. Flat-footing it barely adds anything to the acceleration force you've already got.""

""I can easily take more corners in third without feeling like the car is about to lag and require a drop to second. The new bottom end allows the car to build up from low rpm quicker than before and get back into the meaty sweetspot of rpm nirvana. In a typical long left sweeper, the car just felt magical powering through it in third.""

I really can't say how impressed I am by your workmanship. You have reached the point where you have pleased the customer (hey! I'm super happy!!! lol) and yet you still perservere to get the best possible results you can attain. You loyalty and integrity is above reproach.

I can guarantee you 100% that one day I WILL buy a top-of-the-line Subaru WRX STI and I WILL be paying you to tune it :D
turner_822 wrote:Hey Edward,

Thought I would write a little post about your magnificent work for people to read!! I drove 3hours down to the coast yesterday and wow! Really found regular driving a huge difference. I had a passanger (admittedly a small one lol), a boot load of luggage, full tank of fuel and the car felt lighter then ever!! The engine immediately responds when I put my foot down and I could feel it pulling uphill and through corners like a dream!! 3000-4000rpm has SO much more then it used to because I'd always have to drop down a gear whenever I approached it.

General day-to-day driving is unrecognisable!! I find myself constantly overshooting corners, missing apex's and trying to jam my brake pedal through the floor because it just really picks up SO much more speed in the low-mid range. I was driving and saw a big, long, smooth, clear straight and couldnt help myself; I wound 4th out to ~170-180km/hr and I can tell you, it wasn't looking to slow down anytime soon!

In my opinion, the entire car was so dull for one reason: the engine was a second or two behind the throttle. Now when I jump on the throttle I get my head thrown back!! Not because of huge forces or anything, but just because im not ready for it!! I keep subconsciously trying to think "ok, I have a second before it takes off" and it useually results in "ok, I have a...OH CRAP!!!!"

Rev limit of 7200 is boarderline terrifying!! The car just keeps howling louder and louder and i'm just waiting for the valves to jump out and perform the riverdance on my bonnet! 2nd hits 100km/hr and 3rd.......well I wasn't really looking at the speedo when redlining 3rd lol :o I know it isn't the best treatment for your engine but hey, I take care of its servicing and I bought this car to excite me, not to sit shining in the shed!!

Considdering the relativly tiny amount of money you have charged me for your services Edward, it is dollar for dollar THE best thing I could have done to my car and would reccomend you and XRT to everyone that will listen!! I promise you I'll be back one day with a brand-spanking-new WRX STI :D

Cheers mate,
Nick

turner_822 wrote: In my opinion, the entire car was so dull for one reason: the engine was a second or two behind the throttle.
It did feel that way, didn't it? The stock tune also made the car feel somewhat heavy and underpowered.

I've come to realise that the stock tune is crap simply because Subaru don't know where and how you are going to drive your car. The stock tune is safe in the driest and coldest conditions all the way through to the hottest and most humid conditions. You've now discovered what can happen when your car is tuned to your local atmospheric coniditions (as did I). That said, I found Edward's tune to perform admirably in summer, but the best performance is always going to come in cooler, denser temperatures.
turner_822 wrote: I am only doing basic mods because WHEN (not if!) I get an STI I will spend stupendous amounts of cash to get everything as good as it gets, then see if I can stay alive long enough to enjoy them! :D
Keep modding the 2.5i as you go even before you get the STi (mostly because it's just fun to do, and you learn a lot!) - I'm in the process of installing a full set of STi Brembo's, discs, braided lines and STi master brake cylinder on my 2.5i this weekend because my spirited mountain driving is causing me brake fade! Should allow me to stretch the legs of my own tune a bit further! :)

I agree, I think the stock tune is just generic for all conditions/drivers. That's why I got so annoyed hearing "ohh mate, can't tune that! Factory tune will be perfect". Then Edward walks in and turns the thing into an animal!!

I have learnt so SO much working on my car. Coming from road bikes its a whole new world but I'm learning and loving it :D

I have found the brakes to fade especially through the mountains and it leads to some butt-clenching moments lol. I am looking to upgrade the suspension and firm it up a bit, then its onto the brakes.

Subject: RE: v8

I first installed in back before my surgery while I was on holidays and drove home with it. I can't really remember how v6 was but I remember having some amazing fun on the way home with v7 when I was in the high rpm range

I remember noticing some slight changes in the top end. It seemed to hold on to the power as it went over 5000rpm. When the car really starts to surge at around 4000rpm the power seems to drop away a bit at about 5000rpm. v7 felt like it improved this and helped it to hold onto the power. Instead of that fantastic surge of power between 4000-5000 fading away just as I start to enjoy it, it now seems to last longer. The combination effect of all the changes has made me think twice before planting the throttle coming out of the turns!!

I specifically remember a winding set of turns through the mountain where it was perfect to just hold in 2nd gear, working between 3000-6500rpm felt fantastic!! The car felt VERY aggressive and I went on/off the throttle and I could feel the power wanting to kick the car into under/oversteer (AWD working hard to keep me alive lol).
turner_822 wrote:Those graphs are awesome Edward!! They tell such a small part of the story, the car feels FANTASTIC to drive!! The best part is re-loading the stock and feeling the boring and sluggish it is. With stock settings, I put my foot down and its like the engine takes a moment to decide what to do...and I get bored, lol.

It is like two different cars!! The way it picks up speed down in the low RPM, the extra torque and the way it immediately reacts when I touch the throttle. It's hard to describe but put it this way, I took my friend for a drive before and after v7 and had him giggleing like a school girl by the time I'd wound out 3rd!!

I feel spoilt rotten and lack the works to thank you for all the extra time you spent tinkering with this Edward!!
turner_822 wrote:The car felt even faster! It was hauling when I first set off with the intake temp around 18 degrees. Then it stabilized at about 23-25 degrees but it was still going really well. I noticed in particular how it behaved when cruising in 5th gear at 100km/hr. It sits at about 2600rpm and when I put my foot down it instantly starts picking up speed and pulls up hills really well. It has this real surge between 2500-3000rpm that was definitely not there before, in fact it used to feel like crap when you put your foot down in that rpm range but now its great!!

I can't get over the pull it has between 4-5000rpm. Going from 1500rpm, its a bit slow but then really picks up between 2500-3000rpm. Its a bit slow from 3000-4000 but then it takes off between 4000-5000 and that surge makes for my favourite part the car's performance.

Power seems to fade a bit as it gets higher (5000 up to 6500rpm) but it's still way better then it used to be. I absolutely love the howling noise the engine makes as it approaches 6500rpm, it says just when to change gear. I know its probably howling in pain and agony, but I don't push it that hard very often and my service intervals are now every 5000km or ~4 months (although recently I have been doing a lot of hard driving for logs...)

Biggest imporvement by far though is the low-mid range power, and I find it getting the better of me sometimes on roads that I know really well. It has made everyday driving 10x better. With a supercharger I will definitely be looking to upgrade my brakes to avoid those bowel clenching moments :shock:

To see the difference between stock and v9 still amazes me...especially considdering a stack of local places that basically told me I was an idiot and you can't improve on a so-called perfect stock tune...read the graphs and weep :wink: 98 kW - 108 kW and 172 Nm - 191 Nm.

Nice work Edward, improving on what many called "perfection" lol

turner_822 wrote:Well I had some real fun with v9c. Edward has got the car really dialed in. I will have to log some 3rd gear pulls so Edward can post the graphs but he didn't tell me what he changed for v9c.

Straight away I noticed the difference down low. The power feels so smooth now and that slow spot between 3000-4000rpm is pretty much gone. As I accelerated, it would pick up at 2500, drop off a tiny little bit at 3000, pick up again at 4000 and finally drop off at 5000. Now; the power seems to build really smoothly from 2500rpm right up to 5000 before the power fades away. It just feels like it's reving so freely because it's no longer getting held up by that slow spot between 3000-4000rpm.

Didn't really get out of town so I couldn't stretch its legs and feel for any changes in the high rpm range. I look forward to finding out in the morning though :D

My friend who has driven the car a few times absolutely loved the tune. I didn't tell my older brother (original owner) about the tune and he was very supprised when he first drove it. Also that was only with ?v7 I think. They are yet to see Edward's recent work.

I can say that v17b is probably the sweetest ROM you have ever sent me!
The car just rockets away in the lower RPM like never before, power between 2500-3500 is just perfect.
Short shifting under partial throttle is just awesome! Better then a WRX. It's like the engine reacts to every little input by the throttle so instantly and smoothly in the same way that larger NA engines do
Thank you.

Everything internal on the stock engine has run amazingly well (run >25,000km). I was amazed with the results and the capabilities of the 2.5i stock engine. The only thing I changed was the cams and I actually regret doing that! It didn't need them.

XRT did brilliant work on my car - 10/10

Hi Ed,

Just wanted to shoot you an email and to say thank you for the great service you provided when tuning my car.

As a person who has no experience in tuning, you made it an easy process for myself by keeping patient and instructing me every step of the way.

My Subaru Liberty is now more responsive than ever before and I enjoy driving it more than ever.

Looking forward to trying out the other versions you have programmed for the car in the future.

Thanks

Before the tune my car seemed unresponsive, slow to change gear and overall underpowered.

Even from v0, I felt a change in the car and by the 3rd rom (v1) the cars response of the line was vastly improved! I am amazed at what a tune can do to how a car behaves!

V1a and v2 seemed to make slight adjustments to the cars downshift speed but overall made it seem much more refined.

I am very happy with the end result of my tune, unfortunately my cars seems limited as to what Edward could get out of it because of the automatic transmission. Regardless it's been a great improvement and if I ever get another Subaru, I'll be asking Edward to tune it :)

Cheers,

http://www.xtremeracingtuning.com/forum ... f=40&t=400
I came across Edward and XRT quite by accident when perusing the Australian Liberty forums. Initially I didn't pay too much attention as he was "just another tuner" but I noticed that a lot of people were posting up crazy reviews about this guy who was able to achieve tuning amazing results without ever seeing or sitting in your car. This intrigued me as I didn't know you could tune-by-email.

As I explored further I discovered the wonders of RomRaider and open source tuning and wanted to know more. The idea of tuning my own car didn't enter my head until I saw a post from Edward asking if anyone would like to explore the idea of tuning a 2.5i. I looked around and found that no-one had answered his call, so I had no way of determining whether or not anyone else had done it and if there were any results to examine to decide if I wanted to do it myself.

Edward had, however, tuned a lot of 3.0 cars. Since they are NA I figured that they can't be too different to my 2.5i. I read several 3.0 reviews and they were all glowing. Some of the improvement figured reported were downright amazing.

Since I couldn't find any negative opinion about Edward other than the paranoid types who think that plugging a laptop into a car is a good way to turn it into an all-wheel-drive brick, I took the plunge and emailed Edward some questions, which he promptly answered right away. Yes, he'd never done a 2.5i before and was looking for a suitable candidate. What also surprised me was his price - it was very cheap and this also spurred me on to consider taking him on.

But I was still up in the air about tuning a 2.5i. It's only a 2.5i after all, so it can't possibly improve as much as you can improve a 3.0 or a GT, surely? Edward asked me to send him a copy of my car's stock ROM so he could examine it and compare it to a 3.0 to evaluate where gains could be made. I went and bought a Tactrix OpenPort 2.0 cable and got him a ROM. I figured even if he wasn't able to support it, I could have some fun monitoring the car with the cable.

The next day Edward gets back to me and says the 2.5i and 3.0 ROMs are different beasts, but they do share a number of similar tables and Edward found other areas in the 2.5i ROM that he thought could use some tweaking. In short, he would definitely be able to support it and some gains should be achievable. I had already figured if I can get the driveability of the car improved, especially from-standstill acceleration, then this would be a Good Thing (TM). I was still with the expectation that I couldn't expect much in the way of more power or torque from a 2.5i, though.

Well, I was proved wrong. Very wrong.

It only took 12 late evenings, 14 ROM revisions, four tanks of fuel, more than 1,600 kilometres of test driving, and a partridge in a pear tree to arrive at what I now enjoy today - a road weapon! Edward has increased my power from 101kw at the wheels stock to 111kw, and raised my torque from 175nm stock to 193nm! That's 10% on both sides! For a naturally aspirated car with no modifications, that is massive! On top of that, my throttle is now incredibly responsive responding to the lightest of touches. The car is so easy to drive, doesn't feel "heavy" anymore and feels like a car that wants to be driven now, instead of being sedate and boring. The difference is so massive, that it's like comparing chalk to cheese and I am absolutely shocked that Subaru would sell these cars in such a massively detuned state.

To those who believe that just because your car is low-capacity and non-turbo that you can't expect any performance improvements, I am telling you right now that you are wrong. Edward has the expertise to squeeze every last drop of performance out of your hardware, and while mods can help, my improvements have come without a single modification - I am 100% stock and I am absolutely loving the car now.

Edward spends the time to properly custom tune your car not only for best performance but to your driving style. You tell him what you want and he delivers. You don't have to be a car expert either - just tell him in plain english what you feel out of the car, how you'd like it to feel and Edward will translate that into the technical modifications required. Your car is FINE-TUNED to ensure it's clean and most of all, SAFE. Safe for your engine and a more responsive car will also make it safer for you as the driver to be able to immediately respond to situations on the road. You will gain more power and torque and the tune will actually be safer for engine longevity than even the factory tune is which in my case showed how easily it could ping under regular high load! FOr the greenies out there, Edward will also deliver a fuel saving too, so his tune will quickly pay for itself over the next couple of years of refilling.

If you only ever do one thing to your car in its lifetime, then make it an XRT tune. It's cheaper than wasting money on buying a full exhaust system for fat sound or bling wheels to look good. A tune gets you so much more out of your car. It's the best bang-for-your-dollar investment you can make.

It has been an honour being Edward's first 2.5i to tune and now every other 2.5i owner can reap the benefits as well. I would also encourage anyone with a 2.0R to come forward and let Edward bestow the XRT nectar to you - you won't regret it! Subaru NA cars are actually really good cars!

Edward is a tuning master. He is always available on email and IM (he never sleeps!), he encourages you to ask questions and he will ask them of you too. He is very open and approachable and this level of communication makes working with him an absolute pleasure. I just cannot recommend XRT highly enough to you if you want to extract extra performance out of your car for minimum outlay. Why are you still reading this? Email Edward NOW! :D

Hi Edward,

In short, the engine feels a LOT different! There is more torque down low (where I need it) and the engine is more responsive to throttle inputs. It is what I thought the car should have been to begin with! I checked fuel mileage yesterday (actual) and it was 20.25MPG. Not good but I drove the car a bit harder than ‘usual’ and had the 2nd gear pull in there as well. Engine revs did not exceed about 4000 (except for the pull). Checked the actual mileage again today after a normal commute to work and back and it returned 25.96MPG in Sport mode. Not bad! Again, engine not exceeding about 4000RPM.

Cheers,

Jim

Hi Edward,

After 3 days of driving the car, another difference is that when the gearbox is in normal mode, and accelerating under light throttle, upshifts occur at less than 2000RPM. This is a lower RPM than before the V0 tune. This NOT a complaint, just an observation. With the added torque down low after the V0 tune, the engine STILL responds better at this low RPM than it did before. This is a good thing!
Unlike our Alfa Romeo whose engine rarely goes below 4000RPM when moving, I drive the Subaru the opposite; the engine doesn’t see much above 4000RPM. I see the Outback as a fun commute/utility vehicle, not as a sports car so that’s how I drive it. Reasonably good power (V0 made a big improvement) and good fuel economy.

All I can say for now is that the engine feels GREAT! The low end is FAR better than stock. And on about half throttle in 1st gear Sport mode, it felt like the engine came ‘on cam’ about 4000RPM. It simply took off!!  Mileage increased from yesterday’s 22.35 to 25.76

Good morning!
Well, it’s been a heck of a time these past 3 weeks including this past week with no emails or internet.
The car runs fantastic! Starts instantly and idles perfectly both cold and hot. Much, much improved low end power which, rarely going much over 3k RPM now, is where I need it. Light throttle upshifts occur at a low 2000 (approx) RPM which I think (if memory serves) is lower than the stock tune. This is NOT an issue mind you; just an observation. Doesn’t matter either because of the increase in low end power. And it may contribute to better MPG.
Speaking of MPG, the first full tank with the V3 tune netted 24.81. Not bad! The 2nd tank was low at 23.44 BUT every year around this time I use the 7 or so gallons of stabilized fuel I store for the generator, lawn mower, snow blower, etc. The 3rd tank, having just filled up yesterday, yielded the best mileage I’ve gotten with the car since we bought it this past August; 25.84 MPG. And this was with ambient temps, on a few mornings, being a bit below 0C! All 3 tanks were run the same; to and from work on the same roads and at the same speeds. About 2/3 of my commute is on the highway at 75-80 MPH (just under 3000 RPM).

Cheers,

I came across Edward and XRT quite by accident when perusing the Australian Liberty forums. Initially I didn't pay too much attention as he was "just another tuner" but I noticed that a lot of people were posting up crazy reviews about this guy who was able to achieve tuning amazing results without ever seeing or sitting in your car. This intrigued me as I didn't know you could tune-by-email.

As I explored further I discovered the wonders of RomRaider and open source tuning and wanted to know more. The idea of tuning my own car didn't enter my head until I saw a post from Edward asking if anyone would like to explore the idea of tuning a 2.5i. I looked around and found that no-one had answered his call, so I had no way of determining whether or not anyone else had done it and if there were any results to examine to decide if I wanted to do it myself.

Edward had, however, tuned a lot of 3.0 cars. Since they are NA I figured that they can't be too different to my 2.5i. I read several 3.0 reviews and they were all glowing. Some of the improvement figured reported were downright amazing.

Since I couldn't find any negative opinion about Edward other than the paranoid types who think that plugging a laptop into a car is a good way to turn it into an all-wheel-drive brick, I took the plunge and emailed Edward some questions, which he promptly answered right away. Yes, he'd never done a 2.5i before and was looking for a suitable candidate. What also surprised me was his price - it was very cheap and this also spurred me on to consider taking him on.

But I was still up in the air about tuning a 2.5i. It's only a 2.5i after all, so it can't possibly improve as much as you can improve a 3.0 or a GT, surely? Edward asked me to send him a copy of my car's stock ROM so he could examine it and compare it to a 3.0 to evaluate where gains could be made. I went and bought a Tactrix OpenPort 2.0 cable and got him a ROM. I figured even if he wasn't able to support it, I could have some fun monitoring the car with the cable.

The next day Edward gets back to me and says the 2.5i and 3.0 ROMs are different beasts, but they do share a number of similar tables and Edward found other areas in the 2.5i ROM that he thought could use some tweaking. In short, he would definitely be able to support it and some gains should be achievable. I had already figured if I can get the driveability of the car improved, especially from-standstill acceleration, then this would be a Good Thing (TM). I was still with the expectation that I couldn't expect much in the way of more power or torque from a 2.5i, though.

Well, I was proved wrong. Very wrong.

It only took 12 late evenings, 14 ROM revisions, four tanks of fuel, more than 1,600 kilometres of test driving, and a partridge in a pear tree to arrive at what I now enjoy today - a road weapon! Edward has increased my power from 101kw at the wheels stock to 111kw, and raised my torque from 175nm stock to 193nm! That's 10% on both sides! For a naturally aspirated car with no modifications, that is massive! On top of that, my throttle is now incredibly responsive responding to the lightest of touches. The car is so easy to drive, doesn't feel "heavy" anymore and feels like a car that wants to be driven now, instead of being sedate and boring. The difference is so massive, that it's like comparing chalk to cheese and I am absolutely shocked that Subaru would sell these cars in such a massively detuned state.

To those who believe that just because your car is low-capacity and non-turbo that you can't expect any performance improvements, I am telling you right now that you are wrong. Edward has the expertise to squeeze every last drop of performance out of your hardware, and while mods can help, my improvements have come without a single modification - I am 100% stock and I am absolutely loving the car now.

Edward spends the time to properly custom tune your car not only for best performance but to your driving style. You tell him what you want and he delivers. You don't have to be a car expert either - just tell him in plain english what you feel out of the car, how you'd like it to feel and Edward will translate that into the technical modifications required. Your car is FINE-TUNED to ensure it's clean and most of all, SAFE. Safe for your engine and a more responsive car will also make it safer for you as the driver to be able to immediately respond to situations on the road. You will gain more power and torque and the tune will actually be safer for engine longevity than even the factory tune is which in my case showed how easily it could ping under regular high load! FOr the greenies out there, Edward will also deliver a fuel saving too, so his tune will quickly pay for itself over the next couple of years of refilling.

If you only ever do one thing to your car in its lifetime, then make it an XRT tune. It's cheaper than wasting money on buying a full exhaust system for fat sound or bling wheels to look good. A tune gets you so much more out of your car. It's the best bang-for-your-dollar investment you can make.

It has been an honour being Edward's first 2.5i to tune and now every other 2.5i owner can reap the benefits as well. I would also encourage anyone with a 2.0R to come forward and let Edward bestow the XRT nectar to you - you won't regret it! Subaru NA cars are actually really good cars!

Edward is a tuning master. He is always available on email and IM (he never sleeps!), he encourages you to ask questions and he will ask them of you too. He is very open and approachable and this level of communication makes working with him an absolute pleasure. I just cannot recommend XRT highly enough to you if you want to extract extra performance out of your car for minimum outlay. Why are you still reading this? Email Edward NOW! :D

Everything internal on the stock engine has run amazingly well (run >25,000km). I was amazed with the results and the capabilities of the 2.5i stock engine. The only thing I changed was the cams and I actually regret doing that! It didn't need them.

XRT did brilliant work on my car - 10/10

No problems. I hope it would be a good reflection of the job you’ve done!

“My great appreciation goes to Edward for the job hi’s done tuning ECU for my car. My story began few month ago when I sold my beloved 3GEN 2.5i Liberty and upgraded to 4GEN 2.5i. What was supposed to be an upgrade, left me with a bitter disappointment of 4GEN performance compare to 3GEN. Car was sluggish on response, slow to accelerate and had a noticeable lag in acceleration during gear shift. After few days searching through internet forums I came across posts describing similar situations and the way to fix the problem was custom ECU re-flash. That’s how I came across with ECU tuning service provided by XRT. I made final attempt to rectify issue at Subaru dealer service, they had injectors serviced, did upper engine clean, checked spark plugs, reset TCU and told me that as far as they concerned car is operating within manufacturer specification (i.e. it’s still sucked to drive it). I had contacted Edward, described him my situation and got an answer I hoped for – problem can be addressed by custom ECU tuning. I got a list of things I needed to begin the tune from Edward. When I was ready to start, he connected to my laptop remotely and configured it, so it was easy as a breeze. V0 ROM he prepared for me brought back that excitement I had driving my beloved 3GEN. My 4GEN Liberty became more aggressive, it wanted to jump when I pushed accelerator, lag of power and acceleration disappeared. It was fun do drive this car again. V0 was a bit rough on AT, so occasionally I felt knocks during gear shift, but v1 ROM has addressed this and made AT shifting nice and smooth. The real joy was brought by v2. First notable thing was that gear shift now occurs at lower RPM compare to stock ROM with better power delivery. Shifts with stock ROM occurred above 2500RPM for 1st and 2nd and above 3000RPM for 3rd and 4th. With v2 shifts for 1st and 2nd occur around 2000RPM and 3rd and 4th around 2500RPM. I felt improved performance in 3rd and 4th gears were normally all driving occurs. Even when accelerating uphill, AT rarely downshifted from 4th to 3rd. Most of the time it was just happily sitting in 4th adding up some RPMs when I pushed it. Start from traffic lights became such fun! V2 was giving me such joy of looking at the faces of some unsuspecting victims trying to race me from the traffic lights. :) Driving for about two days I have noticed that car became more fuel efficient as well. On a normal week I was getting about 11.6L/100km city driving. After few days with v2 am getting 9.6L/100km in the city. I suspect it might get up a bit, but nevertheless it’s quite impressive reduction. Overall, great job once again. Thanks, Edward!”

Cheers,

Nick.

Wow. The car already feels much better. It is so much more responsive now.
I just went for a drive to give it a quick test and thought I may as well send you the log. I’ll get a better log tomorrow and do some 2nd gear pulls like last time.

Cheers,
Paul

Well v1 was lots of fun.
It felt like it had heaps more power than before. I think I had a stupid looking grin on my face every time I put my foot down.
Not only that, everything was so smooth. It was actually hard to tell when the gears changed in auto mode.
One of the big issues I had with the stock tune was that when taking certain corners at low speed in auto mode, the car would lose a lot of momentum and then very aggressively drop back a gear. This issue can be reproduced on demand at a particular corner near my house. With v1, that issue seems to have gone away.
I’m very happy with the performance of v1.

Hi Edward,

After almost of two weeks of you tuning the car. I should say the car has been totally transformed, the car sluggishness in the CVT transmission has been fixed, it tends to shift better now than before. It used to stay too much in the higher RPM before it up shift, this makes the car sluggish, noisy and annoying sometimes especially in low speed. The delay or lag in the response of the car when I’ve stepped on the accelerator pedal has also been improved. It completely changed and sharpened the throttle response. Overall, the car feels much lighter, smoother and accelerate much faster than before. When driving on the traffic jam, I can immediately feel the car responsiveness as I can quickly change lane, low to mid end power range definitely have been improved tremendously. When on the freeway, I can easily pass other cars as the car feel so responsive. The engine just revs so freely now and I absolutely love it.

For these past few days, I’m always really excited and have been looking forward to driving the car with your ever improving tuned rom version. This morning, I tried to assess and to remember everything from how my car feels now as compared to before, I started to realize how much you have done to the car. I really love the car now even more and intend to keep it even longer!

Regards,

Gerry
