DiabloSport Unlocked Replacement PCM for 2015 Jeep Grand Cherokee 5.7L 6.4L HEMI - PCM-JGCV815

The DiabloSport PCM-JGCV815 is an unlocked replacement powertrain control module for the 2015 Jeep Grand Cherokee 5.7L 6.4L HEMI. The factory module on these vehicles is locked; this one is unlocked and programmed for your vehicle so a DiabloSport inTune i3 or Trinity 2 can flash a tune. On its own it changes nothing.

Buy it if you already own an inTune i3 or Trinity 2 from another vehicle, want a second PCM so you can swap back to stock for dealer service, or need a vehicle license on a new vehicle. If you need the tuner too, the inTune i3 PCM swap kit 8321-X and Trinity 2 EX PCM swap kit 9321-X and PredatorX kit DS-MFD15 bundle the device with the PCM cross-ship.

Frequently asked questions

Do I still need a tuner?

Yes. This is the unlocked module only. To load a tune you need an inTune i3 or Trinity 2. The 8321-X, 9321-X, DS-MFD15 kits include the device.

Will it work with HP Tuners or another brand?

No. DiabloSport unlocked PCMs are matched to DiabloSport devices only.

How does DiabloSport get my VIN?

Through the DiabloSport PCM form that comes with the module. Fill it in with the VIN and return it with the PCM paperwork; nothing is needed at checkout.

Why save the stock calibration first?

The stock file has to be read from the original PCM before it is removed. Without it there is no stock calibration to return to later.
