Tuned ECM 2002–2005 GM 2.2L Ecotec Engines

Unlock the full potential of your 2002–2005 GM 2.2L Ecotec engine with a custom ECM tune designed for race, off-road, and demolition derby applications. This calibration removes factory limitations while optimizing engine performance, reliability, and simplicity for stripped-down builds.

The tune is built to improve throttle response, fuel delivery, and overall drivability while eliminating unnecessary factory components that are not needed in race or derby environments.

Features

• Precise timing adjustments

• Optimized fueling tables

• Increased rev limiter

• Modified temperature parameters to allow the engine to run hotter

• Unnecessary sensors eliminated

• Security / VATS removed

Installation Notes

This tuning is compatible with the stock wiring harness, but the following modifications are required for proper operation:

• Install a push-button start

• Hotwire the fuel pump

For the easiest installation and cleanest wiring setup, we recommend pairing this tune with a Simplified Harness designed specifically for 2003–2005 2.2L Ecotec engines.

For demolition derby applications, it is also recommended to hotwire the transmission to prevent unwanted shifting issues during competition.
