Xtreme Racing Tuning

V0 Driving Stats. Finding rom completed.

Higher or Blue/Red lines are v0 dyno'es.

Fueling is still close to 14.7AFR before the car shifts to Normal mode. Once this can be rectify, I will see if the torque will come up before 2500rpm. AVCS has not be adjusted yet and will not be until the fueling is finished.

Some dyno runs were affected a bit due to ignition being pulled due to pinging and maybe old spark plugs.

Dynoes in KW and Nm

Software dyno'es based on rpm. Speed dyno's are 10units less.

Heat really affect NA engines quite a bit. A CAI is really needed, including keeping the air cool enough until it reach the engine. Water Injection is really needed

I have been working with Edward Millington aka west_minist for about a week now on creating a safe performance enhancing tune for my MY05 3.0RB 6MT. I was in contact with Edward months ago and he seemed very keen back then to get his hands on a H6 rom when the definitions became available on Romraider.

To begin with I emailed Edward my standard rom along with a collection of logs which consisted of normal driving around town including a steep climb up Bulli Pass. I then continue to log giving him a good example of cruising at 100kph to 110kph. Nothing illegal of course.

Then on level road surface I perform a series of 3rd and 4th gear pulls at WOT from about 2000rpm to 7000rpm. I perform these logs in both directions as requested by Edward.

Once I have collected all the data I then email the logs to Edward.

It doesn’t seem to matter when I email Edward he either emails me immediately or shortly after from his home or from his Blackberry. The guy must never sleep.

I also speak to Edward in Barbados via Skype. Very handy indeed.

Edward then analyses what I have sent and makes changes to the rom accordingly to remove knock etc and emails me back the new rom which I then flash onto my car’s ecu and begin the logging process again.

So far we have sorted the DBW maps and worked extensively on eliminating knock from the rom and have stabilized the IAM which previously was all over the place. Subaru tuning leaves a lot to be desired believe me.

So far without even touching AVCS or adding any timing the car feels great. Very smooth power delivery and the jerky power band that use to kick in has gone replaced by linear acceleration.

Edward is very knowledgeable and knows his way around a Subaru’s ecu. He has tuned many Wrx’s and GT Liberty’s. He has software that enables him to see dashboard on his PC that once the data I send him is loaded it’s as if he’s driving the car. Very cool indeed. I’ve seen a screen shot of it.

I look forward to flashing Version 5 on tomorrow and continuing to work with Edward in developing a tune to unleash the beast within the H6.
