Just got my FRPP 3.73s and Tlok installed. Anyone know how to change/update the tuner so it knows I am using 3.73s. I use a SCT X3, doesn't seem to be any of the menu choices.
Plug the tuner in and go to the screen and reload whatever tune you are running. Before it uploads the tune into the car it will ask you if you want to adjust options. Say yes and scroll through the list of options until you find gear ratio. Scroll through the list until you find 3.73. Then press select and then press cancel to save your changes. Then the X3 will load the updated tune into your car.
