Show original supplier description
This chip connects inline with your vehicle's Inlet Air Temp sensor and Exhaust Air Fuel Sensor harness, enabling a richer fuel trim remap. It is engineered to deliver a significant 15% horsepower increase and notably stronger torque, improving acceleration and overall power delivery across the entire RPM range. Installation is straightforward for tech-proficient owners, typically completed within 45 minutes using basic wiring tools. Once installed, the chip allows for fine-tuning via a remote adjustment knob. It provides noticeable seat-of-the-pants power gains and improved throttle response while maintaining stock drivability and ensuring reliability and service life remain unchanged. The chip also allows for easy reversion to original Air to Fuel Ratio settings with a switch. It is compatible with various BMW models and years, with a wide range of selectable options available. Owners can feel confident that their car will perform tangibly better with supplemental power and potentially improved average fuel economy.
