2006 HHR 2.4L Ecotec Tuned ECM
More Power, Zero Security Lockouts.
Stop letting factory security lockouts and weak stock tuning hold your Ecotec back. This is a complete "Buy It Now" tuned ECM for the 2006 2.4L Chevy HHR.
I provide the computer already flashed with the performance dialed in and the security stripped out. It’s a true plug-and-play solution built specifically for the demands of a racing or derby environment. I’ve gone through the core settings—adjusting timing, fuel, and idle—to ensure your 2.4L stays in the fight until the end.
Price: $250
Performance Adjustments
This isn't just a stock replacement. I’ve optimized the logic to make sure this computer is built to perform in the arena:
Security Removed: VATS/Anti-Theft is completely disabled. It starts every time, no questions asked.
Aggressive Timing: Remapped to squeeze every bit of power out of the 2.4L engine.
Performance Idle: Meticulously set to keep the engine responsive and ready to hammer.
Fuel Calibration: Optimized for consistent power even under heavy loads and high heat.
Higher Rev Limiter: Pushed up to give you a wider power band when you need to stay in it.
