    2015 6R80 base and sport shift map tuning

    Made up a simple excel file for those tuning these new cars...Converts the OSS speed to engine RPM for a reliable shift point vs rpm. I was fighting an issue with the car sometimes shifting at 6800 and other times reaching the 7100 rpm shift point I had set, turns out I needed to up the shift map in the base point (regular drive)..also good for tweaking the downshift schedule (get rid of the delay when you floor it).

    Just delete the inputs under the OSS side and copy paste yours and then you can make the changes to get the rpm point you want for that particular throttle area and the other side will populate with the engine rpm.

    Thank you for taking the time to do this. I had intended to do it, but.... I'm a busy guy. :-)

    Anytime I can help! I figured I would share it as I made it up to make seeing the changes quicker than multiplying one cell at a time. Tuning this transmission has been the most time consuming part of my 15 GT, but one small tweak at a time, it is getting there. Still learning as I go

    45ANNAGT, I received your PM and the spreadsheet I made is for the newer (15+ models). What kind of shift issues are you having with you 11 GT that you are wanting to work on?

    Wanted to get my car to shift based on RPM and not MPH for WOT. IS it possible to adapt the excel sheet from a 2015 to an 11-14 Thanks.

    Post your current tune , modifications and if possible a log with WOT shifting with the usual parameters..The earlier model coyotes are fairly straight forward with tuning, especially WOT stuff.
