just got vafc, with a fpr and a/f gauge. so besides a dyno i’m set to start tuning. i’ve already played with it a little, i’m basically leaning most of the lower points since i had a chipped ecu already and wanna save some gas. i dont really understand the mismatch ecu/afc correction thing. also, what would be a good vtec crossover point for a near stock b17a? thanks
i’m probably telling you what you don’t want to hear, but the best way to tune your car is on a dyno. if your b17a is near stock, best bet is to just keep the vtec engagement rpm where it is, 5600/5700 rpm’s.
