When preparing to program your vehicle, you will have the option to change
certain parameters. Choosing YES when prompted to "Create a custom

The following customizable options are available:
Gear Ratio
The Evolution has the ability to correct for modified gear ratios. Do not
change the value displayed on the Evolution unless you have changed the
rear differential gear. For 4WD vehicles, both the front and rear differential
gears should be the same.
Some reasons for changing gears ratios include:
1. To maintain the optimum ratio between the engine RPM and tire RPM.
Changing tire sizes affects this ratio. Changing the differential gear helps
to restore the proper ratio.
2. When drag racing, changing to a higher gear will provide more torque off
the starting line. There are formulas that show the best gears to use based
on HP, vehicle weight, as well as other factors. Be aware that when
running higher gears your engine will run at higher RPMs and your fuel
economy may suffer.
