I have been doing research on afc hack and I see a major problem was that the car would bog and or sputter at part throttle because the afc only controlled the WOT fuel curve. My question is does the new S-AFCII or the new VAFC with the high and low throttle adjustable curves fix this problem.

If so what settings does the low throttle curve need to be set to with some rc 440s?

 

also would like to know

 

i have the same problem... my car even stalls, and its AUTO!

 

nope, you can only tune open loop w/ afc. i think it's like the upper 1/5 of the fuel map.

Are you talking about the hesitation when you cross over the injector shut off point? thats around 6% throttle I think. you can't fix it. the map is too streched out w/ the hack. DL uberdata and be a happy booster.

 

i never have had any hesitation with the hack or any drivability problems... do you have anything gto tune it with?
