    I've already set the STFT+LTFT graphs to the RPM values on the VE tables. Wanted to be sure I'd be comparing "apples to apples".

    Thanks for your reply. I guess that I wasn't very clear in my original post. I've read IN THIS FORUM that the VE tables can be used to adjust the STFT+LTFT when the Neural Network is disabled. ...

    VE tables VS STFT+ LTFT

    I have a 6.1L Challenger with a manual trans and a Whipple supercharger kit. Otherwise, the engine and exhaust are stock. The STFT+LTFT values for both banks are quite negative (mostly double...

    Kmoney -I appreciate your input and agree that it's possible there could be some underlying cause for the Bank 2 rich code. However, the scenario that throws the code is very specific and nothing has...

    TBRtuning - Were you asking me to e-mail you???

    If I added a wide-band, I'd add a DUAL wide-band as MOPARMATTY suggested. What brand, that is considered accurate AND doesn't cost 5 bills, should...

    Thanks TBRTUNING. I haven't had any obvious miss on cold starts with the Whipple tune although the cold idle is a little rough. Is there some kind of tuning "fix" to ease the LTFT's into running...

    Your advice is appreciated. I've only seen one other 4L60E Shirt Timing chart and that was for a Corvette. The Y-Axis, top to bottom read: 1 -> 2 shift, 2 -> 3 shift, 3 -> 4 shift. Listing...

    I haven't sped up the automatic shift points yet. They're a little bit slow for my liking but not horrible. (I assume DBW is drive-by-wire.) I don't know if the 4L60E was ever supplied from the...
