Ideal for enthusiasts and professional tuners alike, this modified PCM provides a foundation for custom tuning that can optimize power, torque, throttle response, and overall drivability. It replaces the factory PCM with a version that is unlocked and ready to accept performance calibrations tailored to your specific modifications and driving preferences.
The DiabloSport Modified PCM offers a range of features that make it an essential upgrade for serious Ram 1500 owners looking to enhance their vehicle’s performance:
The DiabloSport Modified PCM is engineered to meet or exceed OEM standards for durability and reliability. Built with high-quality electronic components and robust firmware, this PCM is designed to withstand the demanding conditions of daily driving and high-performance applications. Its unlocked status is achieved through precise reprogramming, ensuring seamless integration with your Ram 1500’s existing systems without compromising safety or drivability.
Installation of the DiabloSport Modified PCM is straightforward and requires no permanent vehicle modifications. The PCM is a direct replacement for the factory unit and is typically located in the engine compartment on the right side of the firewall in the Ram 1500. Prior to ordering, you will need to provide your current PCM Calibration ID to ensure compatibility. It is recommended to consult your vehicle’s owner’s manual or service guide for exact PCM location and removal instructions.
Once installed, the modified PCM must be programmed using a compatible DiabloSport tuner (sold separately) to load your desired performance calibration. This process is user-friendly and supported by DiabloSport’s software and customer support resources.
This modified PCM is perfect for Ram 1500 owners who want to take full control of their truck’s performance tuning. Whether you are upgrading exhaust, intake, or other performance components, or simply want to optimize your vehicle’s power delivery and throttle response, this PCM provides the essential foundation for custom tuning. It is also ideal for professional tuners and performance shops specializing in Chrysler, Dodge, Jeep, and Ram vehicles.
