so im trying to go with some bigger injectors on a stock ecu. i was just wondering if a safc2 will allow me to use larger injectors(750+) and i also heard it will let me get rid of my MAF. i_love_triangles said that. is he right.

you can use an Safc for tuning.

but you have to keep the MAF, as it is that signal that it modifies before it goes to the ECU...

phinsup

yes you have to keep the MAF, the afc controls your air to fuel ratio based on increments of RPM, so you can add or subtract fuel % at various RPMS. make sense?

not to rag on any one but I_Love_Triangles is a noob so till you get a responce from someone with experience ..... . . . . . . . . . .

thansk but i still dont really understand about the injector part of my question. "can i run bigger(750+) injectors while using safc and a stock ecu?

Furb

yes you can, because the ecu doesnt know you put bigger injectors in, so it will run pig rich!

you can use the safc to decrease the value of your AFM so it injects less fuel to compensate for the bigger injectors.



just make sure u use the right impedance injectors

ok thank you very much. and i assume that emange would also let me run bigger injectors?

Furb

emanage does the same thing as the SAFC, as it is also a piggyback fuel computer.

problem is, there is very little knowledge in tuning the emanage from what i've heard...
