Dodge PCM Service - GPEC4 - Upgrade Only

Tune the 2.0L Hurricane turbo four. Dodge, Jeep and Ram vehicles with the GPEC4 engine computer have to be upgraded before they can be tuned. This one-time HP Tuners send-in service upgrades your PCM so you can scan, data log and flash a custom tune through the OBDII port.

This is a send-in service. Your PCM has to come out of the vehicle and ship to HP Tuners, so the vehicle will be down while it's away. Please read this whole page before ordering.

Will it work on my vehicle?

• 2018-2021 Jeep Wrangler 2.0L (GME Hurricane I4)
• 2022-2023 Ram Rampage 2.0L (GME Hurricane I4)
• 2023-2024 Dodge Hornet 2.0L (GME Hurricane I4)

What else you'll need (sold separately)

• The Dodge 2018+ Smart Access Cable. It is required on every one of these vehicles. Order it separately so it isn't held until your PCM ships back.
• Universal Credits to license the PCM. Check your vehicle's credit cost with our lookup tool.
• An HP Tuners interface. The Rampage and Hornet need an MPVI3 or MPVI4. The Wrangler 2.0L works with an MPVI2 or newer.
• The latest VCM Suite BETA software (free from HP Tuners).

How it works

1. Confirm your vehicle is covered and place your order.
2. Our team emails you the order number and the HP Tuners shipping form, and collects your VIN and stock tune file. HP Tuners requires both before the upgrade.
3. Remove the PCM, pack it carefully with the completed form inside, and write the order number on the outside of the box.
4. Ship it to HP Tuners with any carrier. Shipping to HP Tuners is the customer's responsibility; the shipping charged at checkout covers the return trip.
5. HP Tuners upgrades the PCM and ships it back.
6. Reinstall it, license it with Universal Credits and start tuning.

Wait for our email before you ship. Please don't send your PCM until you have the order number and shipping form.

Before you ship: important

• PCMs with broken locking tabs or connectors will not be accepted. No exceptions.
• Send the PCM only. Brackets, rubber isolators and other parts may not come back with it.
• This is a one-time upgrade. It doesn't change how the PCM otherwise works, and factory service tools still work.
