Tune your GPEC4 PCM Controlled Dodge/Jeep/RAM with HP Tuners

HP Tuners is proud to offer a complete diagnostics and custom-tuning solution for Dodge/Jeep/RAM vehicles powered by the 2.0L GME Hurricane I4 Turbo engine starting with our GPEC4 PCM upgrade service. We offer a one-time, send-in upgrade service to get your vehicle’s PCM ready for tuning.

This controller can be found in the following supported vehicles:

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

Once upgraded, you will use one of our Dodge Smart Access Cables for Dodge/Jeep/RAM vehicles and an MPVI3 device to connect with VCM Scanner to scan, diagnose, and data log important parameters. Then use VCM Editor to access engine parameters within Airflow, Fuel, Spark, Torque Management, and more to build a custom tune that fits your needs. Plus, our solution provides this access directly via the OBDII port using an HP Tuners interface.

Upgrade Service

Our one-time, send-in upgrade option will upgrade your original PCM to enable tuning in VCM Suite. Simply send us your PCM and we’ll send it back to you fully upgraded for tuning in the latest VCM Suite (BETA).

Make sure to include the make and model of your vehicle, the stock file, and your VIN when checking out (always double-check your VIN for accuracy to avoid delays). This service takes 1-3 business days to complete (not including shipping times).
