Bytetronik now offers ECU Updgrades for your VolkswagenI!
APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to his Volkswagen. 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 are available in multiple stages and torque levels, supporting various octanes both with or without any hardware or transmission modifications.APR Plus software is available featuring a factory matching limited powertrain warranty. Specific software is available for use with a high flow Race DP exhaust system, while all stages are fully compatible with an upgraded intake, intercooler, catback exhaust, or other minor bolt on modifications. Finally, each stage is offered with special “Low Torque” software, designed to limit peak torque for use with an unmodified factory manual clutch, or DSG transmission.

APR Plus ECU Upgrade with a Limited Powertrain Warranty
The APR Plus ECU Upgrade is the first step towards making more power, and it includes our limited powertrain warranty. This simple upgrade requies no engine hardware modifications. . Gains of torque are available throughout the power band, making the vehicle exceptionally quicker in all scenarios.
The APR Plus ECU Upgrade matches the performance of our Stage 1 ECU Upgrade (91 octane low torque version). To get even more power, you can add any of our other Stage 1 compatible products and still be covered under the APR Plus warranty! This only excludes our Race DP and turbo/fueling upgrades. To learn more about APR Plus, please visit the APR Plus website.
If you’re not interested in the APR Plus limited powertrain warranty, and want even more power, check out our other Stages.
The APR Stage 1 ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications. Gains are available throughout the power band, making the vehicle exceptionally quicker in all scenarios.
The upgrade is offered in both high and low torque versions, and is available for various fuel grades. The high torque upgrade may require an upgraded clutch on manual transmission vehicles, or APR’s TCU Upgrade on 6 Speed DQ250 DSG/S tronic vehicles to avoid clutch slip, so low torque software is available.
To get more power, the vehicle can be outfitted with an upgraded intake, intercooler, catback exhaust and other small modifications without requiring any new modification to the ECU.
The APR Stage 2 ECU Upgrade is the next step towards making more power! This upgrade requires a high flow Race DP exhaust system. Gains are available throughout the power band.
The upgrade is offered in high, medium and low torque versions, and is available for various fuel grades. The high torque upgrade requires, and the medium torque upgrade may require an upgraded clutch on manual transmission vehicles, or APR’s TCU Upgradeon 6 Speed DQ250 DSG/S tronic vehicles to avoid clutch slip, so low torque software is available.
An upgraded intake is required to meet the advertised low and medium output power figures, and an upgraded intercooler is required to meet the high output power figures. No ECU modification is necessary to run an upgraded catback exhaust system, or other small engine 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.
