OC'd ECU question
 
I have a 96 with a overclocked OBDII ECU. (7650 Actual, 8000 Indicated redline)

My question is; will a BEGI rising rate AFPR compensate for the stetched fuel maps under boost, and not under boost? Giving my tantops the excess fuel they need? Or will I need to return the ECU to stock?

so long as it is agressive enough yes it should

Cool, I'm cooling to pair the AFPR with a bipes, so i can have enough timing until I get to boost. The overclocked ECU is a mod when you put a faster crystal in the ECU it raises or eliminates the redline. (Depending on how much overclocking you do.) One side effect to overclocking is a lean fueling trend, because it stretches all the existing maps on the ecu. (NA I countered this with a powercard TC2.) With my incoming turbo kit, i want to stay away from piggybacks. I want to Squirt, I'm just waiting on a PnP for 96-97's. If I were to do it all over again I would have gotten a 93. But i got a 96, and i gotta make do.
