For owners of newer RAM 1500 eTorques and Jeep Wranglers/Gladiators, custom tuning has often felt like a frustrating dead end. The factory locked down the computer – the GPEC5 Powertrain Control Module (PCM) – making it nearly impossible to tweak anything. But now, HP Tuners, a reputable name in the aftermarket tuning world, has announced a breakthrough. They’re the first company to offer custom tuning and diagnostic support for these previously inaccessible vehicles.
This is a game-changer for anyone with a 2023-2024 RAM 1500 5.7-liter eTorque, a 2022-2024 Jeep Wrangler 3.6-liter, or a 2021-2024 Jeep Gladiator 3.6-liter. Before this announcement, owners were essentially stuck with the factory settings and unable to personalize performance. Now, with HP Tuners’ solution, you can actually dial in your engine and transmission to perform exactly how you want, unlocking your truck’s hidden potential.
The process involves sending your original GPEC5 PCM (or a spare, if you have one) to the HP Tuners’ facility. They perform a specialized, one-time modification that unlocks full tuning and diagnostic capabilities. Importantly, this is a professional service, and HP Tuners promises a quick turnaround of just 1-3 business days. You’ll also need to purchase their MPVI3 tuning device and a specific 2018+ Dodge Smart Access Cable to interface with the modified PCM.
Once the upgraded PCM is back in your vehicle, you license it using 4 HP Tuners’ Universal Credits. And here’s a major plus: you can also tune the ZF8 8-speed automatic transmission, which is what these vehicles use, with a separate 4-credit TCM license. Best of all, you don’t have to crack open the transmission itself – no physical mods are needed. This unlocks a ton of customization options. Want to fine-tune your shift points for towing or rockcrawling? Done. Need to dial in the torque management for better launches? No problem. Even just making your daily commute smoother is on the table.
The real key is HP Tuners’ VCM Suite software. This is where you get to play with all the factory ECU and TCM settings. We are talking about serious control here. You can tweak things like throttle response, fueling, ignition timing, and gear ratios. Plus, you can monitor engine and transmission data live, which is crucial for getting the tune just right.
Head over to HP Tuners website to get the full details and start the PCM upgrade process. It’s time to take control of your RAM or Jeep’s performance and make it truly yours.
