I use it to:
Force 2wd so I can run higher HP
Input Navigation while moving
Able to open the driver door at low speeds so it doesnt throw the Jeep in Park
Stop the seatbelt ding
Stop the motor from turning off at the stoplight
View the Rear camera while moving whenever I want especially while towing
Calibrate speedometer
and 20 other things it does that I cant think of right now but the Force2wd alone is worth its weight.
Tazer Mini and Pedal Commander and you will think your 392 was a steal at that price because it is probably the funnest vehicle to drive that I have ever owned and I am in triple digit numbers so that says a lot.
When using the Pedal Commander I highly recommend the Force2wd feature which also increases fuel economy.
