REAR GEAR RATIO

Press ‘Y’ if the installed rear gear has a ratio that is different

than the original factory gear. This feature will recalibrate the

speedometer/odometer readings and part-throttle shifting for

automatic transmissions for the new gear ratio. This screen

will now appear:

Use the

s and t arrows to see all of the gear ratios available

for the vehicle. Press ‘Y’ to lock in the gear ratio that is installed

on the vehicle.

TRANSMISSION SHIFT POINTS (AUTOMATICS ONLY)

The shift point option allows the user to change the RPM at

which the transmission shifts

at wide-open throttle to find the

very best shift points for maximum acceleration. For shift point

optimizing, test

only one (1) shift point at a time until the best RPM

shift point is found for each.

When ‘Y’ is pressed, this screen will appear:

Press the

s arrow once for 100 RPM, twice for 200 RPM,

etc. and then press the ‘Y’ button to enter the 1-2 shift point

selection. If there is no change to the 1-2 shift point, enter

a zero, and press ‘Y’. Use this same process for each of the

shift points in the vehicle.

The shift point adjustment range

is +/-500 RPM in approximately 100 RPM increments for

each of the shift points for the vehicle.
