APR World Class Calibration Expertise:
The ECU is powerful, but extremely difficult to master. Without mastery, the ECU must be simplified, removing what makes it so desirable. The result is an incomplete product that often requires end user adjustment to maximize output in limited scenarios. On the contrary, APR Tuning Engineers spent years mastering the ECU to unlock its full potential. With complete access to the thousands of maps, tables and variables within, as well as a high-level understanding of how it works, APR Engineers were able to take advantage of everything the ECU has to offer. Power is maximized in nearly all scenarios, eliminating the need for end user adjustments. High performance operational modes are enabled and calibrated to deliver smooth daily driving, with a snappy and responsive throttle during moments of spirited driving. Mastery of the boost control system makes for an impressively predictable driving experience as the turbo spools quickly, delivering instant power, while torque-by-gear helps with traction control and protects the engine from being lugged out in tall gears. Lastly advanced high-output protection routines are enabled, allowing the ECU to make constant adjustments to airflow and fuel to cool and protect the engine, all without the driver knowing otherwise.
