HyRax wrote:v2 ROM update
This release saw a return to v0a timing but with some bottom end changes that Edward made, so I wasn't expecting the car to be as exciting as v1 was, but I was wrong. The car, while not quite as "brutal" feeling as v1 was, was still a lot of fun and it still felt like an "angry" car. I found second gear to be very deep and powerful and gear changes were still fairly smooth except for 1st to 2nd in hard driving acceleration only which seemed to lurch a little, but not by much. Normal driving acceleration in all gears felt smooth, however.
I found third gear to be very linear in its pull again like v1, and 1st gear also pulled off the line very nicely.
I found flat-footing in 1st gear to exhibit a small stop-start jump, but that was probably me applying too much throttle too early and not letting the clutch slip enough before the car could get physically moving properly.
Interestingly I found reverse gear going up into someone's driveway to do a three-point turn to be very nice! You never think about reverse until you are doing it up a hill, and I found it effortless to get up this incline to turn myself around.
One thing I found with second gear while doing some, er... evaluative hooning, was that when I deliberately changed at 5,000rpm, the car consistently revved up about another 500rpm which felt as though the car was still accelerating by itself - I could see this was the normal auto-rev that occurs in normal gear changes, but it gave me a momentary spook as I thought the car had decided to go off and do its own thing with a stuck throttle.
Overall am I finding the car to be very responsive with an apparent increase in torque in second gear. Acceleration is linear, particularly in third, and when the car is on song above 3,000rpm, that is when it feels the most meaty, so I found myself deliberately changing gears quite high to keep the next gear above 3,000.
Another interesting thing I observed was my fuel economy meter. Under the stock ROM, if I hooned around, the meter's estimated distance to empty very
quickly diminished - we're talking fill up with an estimated distance-to-empty of about 600kms very quickly dropping to 300kms within a few hours of lead-foot action. This time around, despite this current tank being hooned on a lot more than driven normally by a factor of about 3:1, the estimated distance-to-empty is remaining quite high for a change - currently reading 400kms with 130kms burned off on this tank already. Since I am deliberately trying to burn off this tank in a bid to refill it with quality BP Ultimate from another servo, it will be interesting to see what my final kilometre tally will be for this tank.
The idle rpm has been raised from the factory 750rpm up to 800rpm, and this has surprisingly helped moving from standstill more effectively than I imagined - getting off the line, especially if it's a deliberate slow start such as crawling in stop-start traffic, is easier than before.
The v3 ROM which Edward has posted me today will be a longer-term test. I'll be running it for a handful of days to see what learning the ECU will do in that time. As a challenge, Edward isn't telling me what has changed until I've run v3 for awhile, so I'll have to give him a seat-of-the-pants review over the next 24-96 hours!
I continue to be amazed at the noticeable differences between each ROM release. Edward truly is a master of his art. Careful and methodical, he really gets results!
Looking forward to flashing v3 tonight!
