A diesel power module is an electronic device that is designed to optimize the performance of diesel-powered vehicles.
These devices are also commonly known as diesel performance module or diesel tuners.
These devices are connected to a diesel engine control unit (ECU), which modifies the engine’s performance parameters to increase performance in the form of power, torque, and efficiency.
Diesel power modules work by changing the programming of the ECU. This controls various engine functions like fuel delivery, injection timing, and turbocharger boost pressure.
By adjusting these parameters a diesel power module can alter the performance of the engine to improve power, fuel economy and other desirable factors.
It’s important to note that some diesel power modules can increase emissions, and may not be legal in all jurisdictions. It’s always best to check local regulations and vehicle manufacturer recommendations before installing a diesel power module.
