    Awesome. That makes it pretty easy. So I can now just scan and start with the WOT RPM shift point first and adjust the MPH after the scan to get it close.

    It has been mentioned before, but as I it understood both conditions have to be met. Here is a shift verus MPH based on gearing spreadsheet from Jim at easyperformance...This was pretty close based on the tune Trannyman did. Scanning confirmed as does the tables in the PCM.

    That is an awesome graph. Now if I put the gearing for 1st 2nd 3rd 4th in the RPM 1, 2, 3, 4 spaces, will it switch the table for me?
