I'm at my wits end here..
Note: Not here to bash the tuner who will be left unnamed, but he's well known. We've tried several revisions to work around the issue, still no luck.
Mod list:
2011 E90 335i
PS2 PWG
Precision Racework Coils
AEM Progressive Meth Controller (disconnected ATM)
FBO's
Recently switched to flash only from MHD BEF. From the first revision the car has had a weird idle, STFT maxed, AFR's thru the roof, etc.. At first, MHD Stage 2 MAP's would work, now the only thing that allows the car to be driven is MHD Stage 0 or the stock bin. My BEF flash doesn't even work anymore.
We've tried the following:
-Flash Back to stock and reinstall MHD
-Samsung Galaxy S8
-LG G2
-Bimmer Geeks Cable
-Amazon Cable
-Samsung dongle
-Google dongle
-Charging while flashing
-MHD 1.53
-MHD 1.24
-New OBD2 Housing and Terminals
It will eventually throw the following codes:
2BEA
2C42
Again, I can flash MHD Stage 0 and it'll drive just fine. There have been times where I load a revision of a custom tune and I can drive, log, and load the next revision and it's back to garbage. I can go back to the previous revision I was able to log in, and back to running like shit again. I've reached out to MHD and they have no idea why this is happening. Just doesn't make sense it would be hardware related if Stage 0 runs just fine.
Do I go ahead and replace the O2?? The thing is when I got to MHD MAP 0 everything works fine...
