you should do it. I went from like a 2008 software (80E?) to the recent one (240E). I drive a MT, and it made low speed, low rpm driving a lot smoother, and it also increased mpgs.
I believe they made a ton of updates on the throttle mapping of the car over time. Benvo may have access to the base files and can see the coding changes, but I'm 100% sure through my personal observations, throttle mapping was changed.
HP increase...ehh, not so sure, I can see how changing ignition, fuel mix, and timing can effect HP, but probably not noticeable, and I'm surprised OP was able to measure it. I'm not sure the increase in HP is within the error range of the dyno. |
Throttle mapping is the same but the car will drive more smoothly.
