HPT GM E90 ECM & T93 TCM Upgrade Kit

The E90 ECM and T93 TCM included in this kit are designed for modern GM vehicles, offering a robust platform for custom tuning. This upgrade is essential if you're looking to significantly alter your vehicle's performance, whether for racing, heavy towing, or simply to unlock its full potential beyond factory settings. The ECM (Engine Control Module) manages your engine's fuel, ignition, and air-fuel ratio, while the TCM (Transmission Control Module) dictates shift points, line pressure, and torque converter clutch engagement. Having both updated modules allows for a more integrated and comprehensive tuning approach.

HP Tuners is well-known in the tuning community for providing the tools and hardware needed to modify vehicle control modules. This kit replaces your stock ECM and TCM with units that are unlocked and ready for programming using HP Tuners' VCM Suite software. This means you can adjust parameters like horsepower, torque, fuel delivery, and transmission shift characteristics to match your specific modifications or driving needs. The build quality of these modules is solid, intended to handle the demands of custom tuning applications.

It's important to note that this kit is not CARB approved and cannot be shipped to California. Before purchasing, ensure your vehicle is compatible with the E90 ECM and T93 TCM, as this is a significant upgrade requiring custom calibration. You will need HP Tuners' VCM Suite software and a compatible interface device to actually tune these modules.
