#38881, "Tuned S-AFC Settings?"


          

Does anyone have any tuned S-AFC settings for running about
10psi. I know I need to dyno it myself but it seems pointless
until I build my motor, so any settings would be helpful.

no smart member of the board will give you settings, every normally asperated 2gnt is different and if you turbocharge it that just adds more uncernity to the mix. one AFC map will work for one person, for the next it may destroy an engine. there is no "safe" numbers you can just stick in there and have it give you instant horsepower, especially at 10 psi. if you're running on stock internals, you'll be blowing piston ring landings in a matter of weeks (EDIT: trust me, 1 day after getting my 1g SMIC with custom piping and a 10 psi boost spike i blew my internals, really sucked!), with AFC tuning (you know how the thing works, tricks the ECU into thinking there's less or more of a load on the engine so it alters the injector duty cycle AND messess with your ignition) ignition will be advanced a lot further than you would probably like.

i reccomend only using the AFC with a turbosystem if you have built internals, a digital air/fuel gauge, an EGT gauge, and at least half an hour on a dyno with the aid of someone who has done it before.
