I have the Yellow jacket in my car and it is set up for an AP1 with 4.77, I am currently putting in an AP2 trans. I realize that the transmissions are differant so I assume I will need to change the settings on this? Can anyone help me with if I do or not, and if so what numbers to change the dial to.

Thanks

 

You'll need another setting => sec. reduction is different.
Just use a sat-nav to recalibrate.
IIRC you don't even have to cycle the ignition for the new settings to work.
Adjust on the fly.

 

Thanks, Im still trying to find the formula for the combo of number to set on the 2 clock wheels

 

Using a GPS for calibrating it made it pretty easy to get it dead on for me when I used to have one. Can't remember how the dials were though.

 

should be about set to about 28. u should definitely calibrate it more precisely with a gps nav though
