With the complexity of modern ECU’s, tuning is essential in order to realize appropriate gains from common engine modifications. The ECU of today is responsible for emissions, fuel economy, protecting drivetrain components and monitoring many sensors. Calibrations from the manufacturer are very specifically designed to optimize all of the above and it is easy to ruin the calibration with the simplest of bolt-on performance parts. Nowadays, it is essential to recalibrate the ECU to take advantage of performance parts and ensure that the engine is still operating in a safe manner.
