when I put my tire size in the Tire/Gear wizard it enters another number. My tires are 26.5" and the tire wizard enters tire size as 20.12". I am having problems getting my transmission because of the huge disparity between scanned mph and actual mph. I have included a log and tune file. Please let me know if anything jumps out as obvious to you guys. You can see the transmission shifts to 4th at 20mph on the scanner. All the shifts are weak and early. the car will not hold first when shifter is manually placed in first gear.
Any help will be appreciated.
