More issues with this thing...or should I say the same old issue but I can just pin point it now with a better wideband.

Running the maft-pro on an NA with speed density. I have the overclocked ECU which leans the A/F out but a walbro which bumps up the base FP a few PSI so to a point they sorta even everything out.

So now with the AEM wideband i can see where by idle FP actually is. I started up the car and adjusted the mainscale to compensate for the ecu/pump combo to get around 14.7 (jumped a few tenths on either side of it). Thought I was good till I revved my car up and the A/F ratio jumped up to around 16. Revved the car again and it was at 12. Again, now at 14. Everytime I revved the car it seemed to settle at a different area.

No idea why it would do that unless it's the ECU. I didn't get a chance to swap in a stock ecu yet however I'm not sure how that would cause it. I am running version 4.65 but I don't see any reason that should cause an issue like that. I will be upgrading firmware along with the new ECU tomorrow.

Bob, hope you can jump in here since you obliviously are the one with experience on both these systems.

To be honest I'm on the last straw with this thing. If I can't get this figured out it might be time to go with the emanage.

PS. My AEM does read different than my maft pro. Must be another problem with these.
