1983 jag xj6 with 94 lt1 and 4l60e current gears are 2.88, I have purchased everything to swap to 3.73 and will be doing that over the Christmas holidays,
I would however like to get a jump on my tune and have it ready to upload when gears are done, I know that my shirt point all need to be adjusted by .77211796 to be correct, but my question is with the speedo scalars tuner pro has 3 different scalars, a regular speedo scalar with a divisor of 22 a scan tool scalar with a divisor of 36.89, a fraction scalar with a divisor of 1.02 And there’s also a time between pulses for stop of 38.42 ms I have been comparing tune files and these numbers are all over the place on every different tune, even with same gears, My tune is from Moe and the numbers he has here must be pretty accurate as it’s almost bang on using a gps! , where would I find , or how would I calculate the new numbers needed for these scalars???
Any greatly appreciated.
