Trying to get speedo and trans shift points changed for 37 inch tires.
ok I can get VSS on the logs and the dash to read correct but after 30 hrs of trying I can not seem to figure out how to get the shift speeds correct with having the vss set correct in the t43 controller
I used the speedo calculator witch got me close on t43 logging ,then figured out how to make the dash read the same but the shift points are off like 8 mpr on the 4to5 and the 5to6 shifts
I tried every thing I can come up with has any one ever fixed this before?
