Flashpaq Jeep 3.8L TJ, 4.0L JK

Superchips puts the mojo in your machine with features that will give you the leg up off-road, as well as put a smile on your face during your daily commute. Owning a Jeep is all about freedom and capability, and we unlock your Jeep vehicle’s potential.

Check out these must-have off-road features that you’ll find only in a Superchips Flashpaq programmer:

  • Real-time Idle Up to run on-board welders and to speed up air-compressor work
  • Tire pressure monitoring system – lower the setting for off-road use to avoid the annoying alarm
  • More control over your Rubicon lockers – use them in 4-Hi
  • Run cooler with the ability turn the electric fan on at lower engine temperatures
  • Crawling Tune off-road throttle-response calibration for more control in 4-Lo

And that’s in addition to more power and transmission shift optimization to turn those big mud-terrain tires, and the ability to recalibrate your speedometer after changing tire size or gear ratios. Superchips is the best-selling brand in the business, and no other company delivers all of these off-road features for the way you use your Jeep vehicle.

Now available for Wrangler JK, Wrangler TJ, Commander and Grand Cherokee.
