Im not sure if this should be posted in piggyback or the ecu section so sorry in advance mods if it has to be moved.
I've read that when using for example an safc, where it allows you to tune the amount of fuel by altering the maf signal to the ecu, that when you alter the signal, the ecu adjust its timing based on the input that its receiving.
Knowing this, How is the timing affected if say I'm adding fuel with the safc or when I'm taking fuel out from the afc.
Is it better to use an adjustable fuel pressure regulator to add too much fuel and fine tune it to take fuel out?
or to add fuel pressure just under what is needed and fine tune it to add fuel where need to be?
Either way i think its best to not have anything dratic like 30% gain or loss on the safc right?
