Well after no response and a few hours trawling through a 7 year old thread I discovered that EFI put new tables into the ECM parameters to control the torque values the trans seen. Now does anyone have a tutorial for these tables and what corresponding tables in the TCM to modify to get a nice shifting Auto, stock and aftermarket stalls? Also a list of PIDS to log? I see people have said to change the shift times at around .3 for low load and .2 at high loads, what area is this on the shift time table? If someone can give me a starting point I would be very grateful and happily do up a PDF with what info I get and my results etc for others to read as there doesn't seem to be anything around for this.
