Blitz Supercharger Wiring Question - Toyota Yaris Forums

KTS · 08-10-2015, 04:09 PM

The setup from post #6 works sufficient I believe.
My AEM UEGO Air/Fuel Ratio Gauge reads 11 to low 12's in boost when the S/C activates.
Issue: The jegs rpm activation switch seems to be faulty or maybe I wired it incorrectly. I wired it to the IGF wire at the ecu. Is this correct?

IGF is a feedback signal from the coils. I would use the TACH signal instead, which is a standard tach signal. The IGF signal is held high and drops for a very short time when the coil fires.
