I am working on a car with 3.69 gears. It has a 38-tooth reluctor wheel (so says Intense) and an ATI 3000 stall TCC. The car had an SRC module in it, but it was getting a P1811 code and I decided to just code the PCM for the gears instead of "tricking" it. I used the Auto scaler in HPT. I put the stock tire size and 4.11 in for the gear ratio and hit "commit". Uploaded the changes and started driving the car around.
The speedometer seems to be reading faster than it should (I had no way to prove it) and the TCC locks and unlocks badly in 3rd and 4th gear. I scanned the car and the gear ratio came in at 1.000 in 3rd gear.
Here is a screenshot of the Speedometer gear ration page:
Any ideas or help?
