The HP Tuners PCM-0J-184AA targets 2018-2019 Jeep Grand Cherokee SRT models running the 5.7L or 6.4L Hemi engine, where the factory PCM ships locked against reprogramming. HP Tuners physically modifies the unit to remove that write-protection before it reaches the customer, so the module can be recalibrated in VCM Editor instead of staying tied to the stock Chrysler tuning strategy.

HP Tuners PCM-0J-184AA Compatibility Notes:

• Matched to 2018-2019 Jeep Grand Cherokee SRT applications equipped with the 5.7L or 6.4L Hemi engine.
• Requires PROM installation or a computer flash to configure the unit for the specific vehicle before use.
• Pairs with VCM Editor software for unrestricted calibration access once installed.
