apexi s-afc and engine codes

i think i heard somewhere that when you have the s-afc hooked up the ecu won't throw any codes. is this true?

hmm... well... for some reason i can't get my ecu to throw any codes out, even when i intentionally unhook something to make it throw a code. i think the afc may have something to do with it.

Yeah, me too. I get codes related to the rear o2 sensor and p-n switch, and now that I have my auto ecu back in while the manual ecu is at jwt, I'm getting the dozen or so codes related to the ecu not finding the shift solenoids.

What other codes do you guys usually through? Ever since supercharging it I get a left bank lean every couple of months, and since my electrical problem, I get ECU can't talk to Automatic transmission occasionally too. All you AFC / MEVI guys are making me nervous

Codes I've thrown:

Left Bank Lean - Ever couple of months.
Rear O2 - Often (weekly) until I put a straight-pipe in - haven't gotten it since.
3-way catalyst - Ever since I put the straight Pipe in.
MAF - Got it once, then it never came back.

Fuel Temp Sensor - Getting it as of 1 week Ago.
P/N Switch - ever since I installed the 5spd ECU. - I think this might be caused by using the Clutch pedal to turn off cruise....which makes sense because the car thinks you just put it into Park at 60mph. It only throws this code after using the CC.

I WISH I was throwing a phantom KS Code - that would explain my powerloss - but unfortunately - no.
