What You Can Adjust

Speed Limiter

Change the top speed that the vehicle will reach before the engine automatically limits the power needed to go faster.

Tire Size

Correct the speedometer if you have changed your tire size from stock.

Axle Ratio

Correct the vehicle speedometer (and fuel efficiency calculations) if you have changed the gear ratio on your vehicle. If no gear ration modifications have been made to the vehicle, then choose the stock setting when the tuner prompts you to choose a gear ratio. This will ensure that no modifications are made to the stock program.

Transmission Shift Firmness

Transmission Shift Points

Change the RPMs at which an automatic transmission will change gears.

Rev Limiter

Regulate the highest RPM that an engine can reach before the engine is electronically limited. Increasing the RPM limit is recommended only for racing purposes. One of the most important ways to protect your engine from damage is to keep the RPMs from going too high.

Active Fuel Management (AFM)

Used to enable or disable the AFM (Active Fuel Management) V8 <> V4 functionality. This will only function if the engine is mechanically equipped to shut off cylinders.
