i know people use fuel controllers with larger injectors to keep them closed longer, but how bout opening them for longer with stock injectors?? or should i just go FMU with stock injectors?

 

FMU with stock injectors.

 

you can't physically hold the injectors open longer, all you're doing with the hack is tricking the computer to think that the air is less dense coming in. Thus it leans out the fuel, but because you have larger injectors they're squirting a proportionately larger amount of fuel into the engine.

You can use the FMU + factory injectors, and its an incredibly cheap way to do the fuel management.

 

So a AFC doesnt do crap for the control of the injectors? I just tells the computer about the air comming and for dsm injectors it says its less dense than normal so the ecu doesnt spray as much fuel?
