so i have the VAFC-II hooked up and when i accelerate it begins to stuter in the begining of every gear. itll jerk like 3 of 4 times befor it smooths out. almost like its not getting fuel or too much fuel. if you know how to fix this comment. Another ? is if i do the system clear on the vafc will it return everything to stock?
running D16Y8 @7psi.

If you're running a turbo setup, you should tune the V-AFC on a dyno, or at the very least on the street with a wideband O2.

so is it possible to leave the vtec signal, vtec pressure, and VTM wires unhooked? so it will just run as a AFC. cuz im chipped on crome

If your chipped on crome, why exactly are you using the vafc? Also your question makes sense, but i dont think it will work since its designed for those functions, but i can not say for sure.

i tested it out drove around and it worked perfect

tune the crome, use the vafc as an afc and dont tune it. use it as a kinda of info thing for voltage, sensor voltage, ect. other wise just sell it. its useless if you already have a tuning device.
