Anyone else running the AEM 30-4100 with stock ECU?
for those that didn't know the AEM 30-4100 emulates a narrowband signal from its wide band signal (mode P04) i was wondering if anyone else is running it like that too. If so how do you have it hooked up?
Mine is setup like this:
A - Tan (Signal Low, signal ground?) to Black (Ground)
B - Purple (Signal High, actual signal) to White (0-1v Analog output)
C - Brown (Heater Circuit return) to Black (Ground)
D - Brown (Heater Circuit 12v switched Supply) to Red (12v supply)
I'm getting awkward short term fuel trims that occasionally lean out like >18:1 AFR and pulling 20% fuel from one bank. The car runs fine and when i get in to it. It goes back to 14.7:1 but I'm afraid to really get on it if its trying to lean out that hard at random.
i do have long tube and the stock O2 thresholds still.
