Bytetronik now offers ECU Updgrades for your AUDI!
APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to his AUDI. The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting vehicle. This is made possible through APR’s optimization of the factory engine management system to take full advantage of the engine’s capabilities, without needing any end user adjustment. The software loads to the factory ECU through the OBD-II port, resulting in a clean and headache-free install.
APR ECU Upgrade Options
APR’s ECU Upgrades support various octanes without the need for any hardware modifications. Each upgrade is fully compatible with an upgraded intake, exhaust, or other minor bolt on modifications.

How APR Differs from the Competition:
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’s Engineers spent the better part of a decade 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’s 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.
APR’s ECU Upgrade has been full tested for the better part of a year prior to a public release. This includes summer and winter weather testing on multiple continents, high and low altitude testing, extensive track testing at multiple road courses, extensive drag strip testing and extensive road and daily driving testing. APR’s test vehicles are full instrumented with multiple sensors, including pre and post intercooler temperature and pressure sensors, pre and post turbine temperature and backpressure sensors, pre and post catalyst temperature and pressure sensors, and multiple pressure sensors throughout the intake system.
