This is a custom dyno-tuned ECU/ECM for the 2003-2005 Chevrolet Cavalier and Pontiac Sunfire with the 2.4L Ecotec engine and manual transmission, built specifically for the bottom-end hybrid configuration.
About the Tune
We supply the ECU and tune it for your specific setup. Every tune is developed from hours of real dyno research and refined for the 2.4L Ecotec platform, giving you sharper throttle response, fueling matched to your parts, and more power across the RPM range than the stock map.
What's Included
Your tuned ECU/ECM, ready to plug in and run.
Before You Order
When ordering, list any engine modifications (cam, injectors, intake, exhaust, etc.) in the notes box on the cart page before you check out so we can tailor the tune to your exact build. All orders are completely confidential.
This ECU is plug-and-play for the listed fitment. Message us before you order if your build falls outside it.
