A custom dyno-tuned ECU/ECM for the 2003-2005 Chevrolet Cavalier and Pontiac Sunfire with the Ecotec engine and automatic transmission. SBR Performance supplies and tunes the ECU — you receive a plug-and-play unit calibrated for maximum performance from your engine combination, backed by hundreds of hours of real dyno research.
About the Tune
Every tune is developed and refined on the dyno using the exact platform it's built for. Fueling, ignition timing, and automatic transmission shift points are all precisely calibrated for the 2003-2005 Ecotec automatic setup. Whether you're running a stock engine or a built motor, the tune is matched to your specific engine configuration, fuel octane, and modifications. This is not a generic off-the-shelf flash — it's a purpose-built calibration for your car.
What's Included
SBR Performance-supplied ECU/ECM, custom tuned for the 2003-2005 Ecotec automatic transmission combination. Plug-and-play installation — no additional programming tools or dealer visits required.
Before You Order
Please list any engine modifications in the order comments at checkout — camshaft, head work, intake, injectors, forced induction, transmission work, etc. The more detail you provide, the better we can calibrate the tune for your exact build. Select your fuel octane and current modification level from the variant options above.
All orders are handled with complete confidentiality. Not sure which configuration to select, or have questions about what this tune can do for your build? Contact us before ordering — we're happy to talk it through.
