i wired in my safc I today with sr 370's and my z32 maf. car started right up but did idle too good and i think had some raw fuel in the exhuast ( it was dark out). i have low throttle set at 0% and -27% straight across for now, i havent driven or reved it yet. my real question is that for the maf the hot wire sensor calibration is suppose to be 2in 5out. well i can only put 2in 5out on the sensor no. screen right after you select hot wire. then after that, sensor cal. screen, my only options it seems is 1in 1, 1/2 out or 2in ave, add out. i cant really read apexi website manuals too well since its so small. what am i suppose to have set on each screen?

I thought it was supposed to be 2 in 5 out for the Z32 + SAFC. Guess I might have to change some stuff around then. Structure you got yours to work good at 1 in and 8 out??

is that with any offset structure???

is that just the change for the MAF and you have injectors calibrated separately, or does it take both the 370ccs and the MAF into account without changing the values of the injectors much?

holy- thats what i was told but it wasnt working good for me. i found the settings that let me trim the injectors as close as possible to -27%. mine is running good. ran 14.300 at the track last night with a 2.389 60' and running pretty rich

ftrs13- the injectors are calibrated separately. with certain setting of the maf it will lean it out alot or richen it alot. the settings i have work and thats all that matters to me. its great having a wideband

yo--thats a file that you can print on apex's website----print it out--its alot easier to read.

I think this is why i went with the z32 maf, wideband and JWT all at the same time.I havent adjusted my afc in/out at all with my z maf and it runs fine.
