    Somehow I missed that when I went through your tune file. Glad you found it.

    STFT can bounce around a lot if it's not set up properly. Can you post a log?... I'd like to see how 'crazy' they are.

    I believe what was said, I'm just not sure the reason why that table would prevent running MAF at idle.

    One thing to note though... the transmission must default to full line pressure without the maf because after setting everything up to tune the VE... the tranny was banging shifts and blew a cooler line...
    The trans tune would have MAF DTC entries in the max line pressure, you can disable those.

  5. Stock maf = perfect idle. Big maf = unstable idle. Any tuning suggestions?
