sorry for the late replay .. but I was too busy this week

anyways, the reason that I pointed that was becasue I've seen waay too many damaged engines because of running the AFC. I'm not sure how much you guys are in the tunning, but timing is THE most important thing to deal with. Fuel delivery just determines if you are gonna be able to run at all, or not. Keep under 12:1 A/F and you start going, but from there it's all about timing.

So, I guess you have an idea how the AFC works ... Anyways, it ensures fuel delivery based on the stock fuel/timing maps of the car/ECU used. When you install bigger injectors (almost a must in turbo app.), you start compensating and adding fuel with the AFC by changing the MAP signal, and therefore telling the ECU that the engine load is different, and the ECU sets different fuel delivery and timing. Doing so, you ensure the fuel delivery, but your timing map gets screwed big time ... and sooner or later you engine does the same. So how do you compensate for the timing ? .. well, one way would be to retard the dizzy (if there's one). Another way would be to install MSD ignition and work from there ... But running only the AFC - as I said above - hell no.

However, AFC works different on different cars .. some may run better, some may not. But in general, you CAN NOT achieve that perfect tune that we all aim at for your car running the AFC.

So as I've said before, if it's gonna be a hack, then EManage it is, because you can compensate the timing with that unit. However, chipped ECU or stand alone is best.

sorry for taking the topic kinda off a little ... I hope you fix your car
