2002-2005 Cavalier & Sunfire 2.2L Ecotec Tuned P11 ECM 

02-05 GM 2.2L Ecotec Tuned ECM (P11)

Looking for a simple, plug-and-play computer for your 2.2L Ecotec swap? This is a fully unlocked and performance-tuned P11 ECM, specifically setup for the early "Gen 1" Ecotec engines found in the Cavalier, Sunfire, and other GM classics.

We take the guesswork out of your wiring. Every ECM is flashed with a custom tune to ensure your engine runs at peak performance without the headache of factory anti-theft locks or limp mode.

🛠 What’s Included in the Tune?

We don't just "flash it and go." We optimize the parameters for off-road and project car use:

• Security Removed (VATS Delete): No BCM or factory key chip required. Just give it power and it stays running.

• Timing & Fuel Mapping: Optimized spark and fuel tables for better throttle response and more "grunt" compared to the lazy factory tune.

• Idle Adjustment: Customized idle speed to prevent stalling in high-stress or off-road conditions.

• Rev Limiter: Adjusted to help you stay in the power band safely.

• Emission Delete: Unnecessary sensor codes are disabled to prevent limp mode.
