stock WRX ECU can optimize ignition timing/boost up to 96 octane.. so its an example of
Quote:ECU is setup be aggressive to advance timing and/or boost if no deto is seen.
the gain isn't that much though.. i heard the difference between ECU on full retard versus full advance is like appx 15hp.. i just hate hearing deto and using 100 versus 91 is a big difference on that front
but yea.. of course i would get much better gains if i actually modded the car and got an aftermarket tune setup specifically for 100 octane
