Predator not uploading/I'm stressing
 
I've tried several times to install the Predator, only to adjust my axle ratio and it will not take hold.My speedometer is way off and I don't know why. I followed the instructions and it looked like I did everything right.

If by chance it was the wrong Predator for my car would it tell me so?

I'm very frustrated at this point.What could the problem be?Anybody else have this problem?

Any input would be appreciated.

Known Issues
F-Bodies (Camaro/Firebird): Correcting of Speedometer after gear change
_______________________________________
Problem: Currently in all versions (v1.00, v1.01, v1.02, v1.03) the axle ratio settings will not adjust the parameters w/in the pcm that controls the speedometer calibration. This only applies to F-bodies that have swapped their rear gear ratio out from factory to a lower gear ratio.

Temporary Fix: Please, from the main Predator screen, select Tune It, Modify Parameters, and then choose Factory Tire Size and Actual Tire Size, and make the necessary adjustments as noted below:

F = Factory Tire Size
A = Actual Tire Size

2.73 to 3.23 - F: 275/40-17 A: 245/35-15
2.73 to 3.42 - F: 275/40-17 A: 275/30-14
2.73 to 3.73 - F: 275/40-17 A: 175/35-14
2.73 to 4.10 - F: 275/40-17 A: 175/30-13

3.23 to 3.42 - F: 275/40-17 A: 235/50-15
3.23 to 3.73 - F: 275/40-17 A: 205/45-15
3.23 to 4.10 - F: 275/40-17 A: 165/40-15

3.42 to 3.73 - F: 275/40-17 A: 275/30-17
3.42 to 3.90 - F: 275/40-17 A: 275/30-16
3.42 to 4.10 - F: 275/40-17 A: 235/40-14


Future Solution: The issue has been addressed and the newest update, v1.04 will incorporate the fix. There is no specific timeframe as to when v1.04 will be released, but as soon as it is we will update the site accordingly. :usa:
