APR ECU Upgrade Stages

APR’s ECU Upgrades are available in multiple octanes levels. Each stage is fully compatible with an upgraded intake, catback exhaust, or other minor bolt on modifications.

APR Plus

The APR Plus ECU Upgrade is the first step towards making more power, and it includes our limited powertrain warranty. This simple upgrade requires no engine hardware modifications, and produces 234 HP with 270 FT-LBS of torque. Gains as high as 45 HP and 59 FT-LBS 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 (87 octane). 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! If you're not interested in the APR Plus limited powertrain warranty, and want even more power, check out our other Stages.

APR Stage 1

The APR Stage I ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications, and produces 234-262 HP with 270-311 FT-LBS of torque depending on fuel grade. Gains as high as 45-73 HP and 59-100 FT-LBS of torque are available throughout the power band, depending on fuel grade and factory output, making the vehicle exceptionally quicker in all scenarios.


APR Stage 1 is available for 87 AKI, 91 AKI, 93 AKI, 100 AKI, 104 AKI, and E60-E85 fuel grades in North America, and 95 RON, 98 RON, 104 RON, 108 RON, and E60-E85 in the Rest of the World.


Please note, our E85 software is not a full flex fuel program. In this mode the engine is only designed to work on E85, as found directly at the pump, including both summer and winter blends from E60-E85. Using traditional pump fuels in this mode may result in engine damage. Do not manually blend with traditional pump fuel or race fuels or use race specific barrels of E85. To ensure proper E85 content levels, APR recommends using an E85 content sensor. Before using Ethanol, educate yourself and follow our switching guide.

Purchasing, Guarantee, and Updates

How to Purchase - This ECU must first be unlocked before software¹ can be installed either by APR or an APR Dealer. If the ECU is locked, you have two options:


  1. Option 1: Send us your ECU
  2. Option 2: Visit an APR Dealer


Option 1: Send us your ECU. We’ll unlock it, confirm what you want, install APR software, bill you if we're installing software, and ship it back. There is no extra fee during the unlocking process. Ground shipping to the continental USA is free. Follow these steps. Please note: This excludes APR Plus. APR Plus must be purchased through an APR Dealer.


  1. Step 1 - Fill out this unlock form, and select VW/Audi MG1 under unlock type.
  2. Step 2 - Mail your ECU to APR, 4800 U.S. Hwy 280 W, Opelika, AL 36801, USA, and include the last 6 of your VIN on the outside of the box.



Option 2: Visit an APR Dealer and purchase the APR ECU Upgrade through them. They will remove and ship the ECU to APR for unlocking and software install, unless they have the tools to unlock the ECU on the spot.


Please Note: At no time during the unlocking process is the ECU opened or physically modified. If the ECU is flashed back to stock, it will need to be unlocked again. If the ECU currently has APR software, and there is an update, a new stage, new feature, or you want to switch octanes, software can be installed by an APR Dealer. Also, vehicle manufacturers issue many ECU part numbers and revisions throughout their vehicle lineup. As such, some ECUs may be temporarily unavailable as new parts and/or revisions are released. If the vehicle’s ECU part number and revision is known, availability can be checked at any APR Dealer or by contacting APR.


Money-Back Guarantee - Try our Software Upgrades for up to 30 days, risk free! If you are not satisfied, return to an APR Dealer to have it removed and refunded.²


Free Updates - If we make an update, add a standard feature, or if the manufacturer issues an update, you are entitled to a free update.³
