750 injector afc settings

[GSX93DSM]

Here's the problem i have 750 injectors,safc, gm maf, 190 rewired fuel pump. I need some settings for the safc. Also i heard I should have something else to tune with. I planned on running between 18 to 23 psi. Should I wait to turn it up.

You need a logger, unless your profile is not up to date. You will need it to keep an eye on knock and timing.

As for the injectors, use your maf translator to compensate for them, not both it and the afc. Zero out the afc. Then, log some pulls and start fine tuning the car with your afc.

I have afc,190 rewired fuel pump,and 750 injectors, gm maft. I have the afc set at 20%- at low throttle is that normal. It was at 0 but the car ran rough, leaned the afc out ran better is that a safe reading.

Do you have a wideband and a logger? While doing that on one car may be safe, doing it on another could be disasterous. It really depends on your setup, you should get a logger and monitor your knock and a wideband to check your a/f. Doing so will help you tell if it's a "safe" combination. As long as you're not knocking and your a/f is in a decent range then you should have no issues, just make sure you log everything so you know if you're detonating your engine or not, don't judge it off the "butt dyno" gl
