I'm trying to determine when the ECU (V6 SE MTX) switches from open to closed loop mode. It simply depends on a throttle percentage, correct?
I'm trying to use a combo of a Proflow MAF and an APEX-I SAFC to tune 19lb injectors in a SVT intake on an otherwise normal V6. I figured the new MAF could take care of the closed loop fuel metering, and then have the SAFC take care of the open loop (no feedback) mode for full or almost full throttle settings. Is this feasible? The SAFC alone hasn't been able to resolve the problem of the car coding (usually takes 2 days to a week to throw a CEL (too rich) on one bank) .
TIA
