Default v-afc question

it may sound dumb, but if you decrease your fuel with a v-afc you will advance the timing. so is it safe to assume that if you add fuel it will retard timing??
i chipped my ecu and i never took out the v-afc, i was just wondering if i added fuel with that would it advance timing.
thanks

if ur ecu is chipped why in the hell would u use the hack to scale your injectors still? mine is still in my car, but i only use it ---- with the vtec crossover point, but projekteg told me that as long as you don't go over +10 or -10 it shouldn't affect the timing.

adding or subrtacting fuel is scaling the injectors.

i thought scaling the injectors is what crome does in the fuel table thang, sorry. i just wanted to know cause i left my v-afc installed and it was still was doing a small amount of fuel correction, but adding fuel not removing

it's easier if you dont think of it as "adding fuel" but "sending a higher voltage MAP signal to the ECU"
