2014 Jeep Cherokee 3.2L ECU Tune

The 2014 Jeep Cherokee equipped with the 3.2L Pentastar engine is a solid performer both on and off the road. The engine is very similar to the 3.6L larger displacement Pentastar engines found in other FCA automobiles, and so responds to similar modifications nicely.

Just like most of the other Pentastar motors, the factory tune has left a lot of performance to be desired in the name of economy. The factory tune comes calibrated for 87 octane fuels, which was the right economical approach for a budget conscious auto manufacturer to make. With the RPM-Motorsports ECU Tune, your 2014 Jeep Cherokee will be re-tuned to optimize the performance of 91 or 93 octane premium grade fuels.

These better quality fuels are able to support improvements in the engine’s timing advance, as well as many other key areas that our tune enhances. The end result is a smoother power delivery, better throttle response across the whole RPM range, and increased top end performance.
