OVERVIEW

The DSG transmission found in the new 2022+ Volkswagen Golf R, GTI, and Audi S3 is nothing short of amazing. It's incredibly fast and capable and requires no hardware upgrades to hold dramatically more torque than what's possible on other transmissions. However, from the factory the transmission tells the engine to limit power and torque. Our engineers fix this by recalibrating the system to maximize torque capacity and clutch pressure to avoided transmission slipping and damage, and in doing so allows the engine to dramatically increase horsepower and torque! We also have stages, at no additional charge, that match our stock and upgraded turbo tunes. On a torque capped MK8 GTI we saw +25-32 WHP and +34-44 WFT-LBS of torque simply by adding our TCU upgrade on top of our ECU Upgrade, and +34-63 WHP and +39-62 WFT-LBS of torque on top of our Stage 3 OEM ECU Upgrade. On a torque capped MK8 Golf R we saw +18-55 AWHP and +23-64 AWFT-LBS of torque by doing the same. This and other changes make the TCU upgrade a substantial upgrade on any tuned vehicle!

Features:

  • Installs on your factory TCU via the OBDII port
  • Increases horsepower and torque on tuned vehicles
  • +25-32 WHP and +34-44 WFT-LBS of torque (MK8 GTI w/ APR Stock Turbo ECU and torque cap)
  • +34-63 WHP and +39-62 WFT-LBS of torque (MK8 GTI w/ APR Stage 3 (OEM) ECU and torque cap)
  • +18-55 AWHP and +23-64 AWFT-LBS of torque (MK8 Golf R w/ APR Stock Turbo ECU and torque cap)
  • Specific stages for use with stock or upgraded turbos supported by APR
  • Maximizes the torque capacity of the transmission and increases clutch pressure to avoid clutch slipping and damage
  • Optimized wide open throttle shift points, launch control strategies, and shift times
  • Maximum safety: protection routines limit over pressurizing physical seals and overpowering electrical components
  • Fully compatible with APR Plus
  • No charge to upgrade to a new stage, free lifetime updates, and 30 day money back guarantee

Increased horsepower and torque

Maximum transmission torque capacity, clutch pressure, and safety

We’ve recalibrated transmission limiters to allow the transmission to see more torque, and to prevent clutch, we’ve also recalibrated clutch pressure. This relationship is dynamic. As the transmission sees more torque, pressure is increased progressively as to not overstress the system or create harsh shifting. Furthermore the system is expertly recalibrated to the physical limits of the system. Too much pressure can blow out physical seals, and too much current can damage electrical components. We don’t simply turn off the limits and crank pressure to the maximum as a finely tuned balance is necessary for component safety.

Optimized wide open throttle shift points

The factory wide open throttle shift points were designed to match the factory output of the vehicle. With tuning, they can be optimized future to improve acceleration times. For the best results our ECU and TCU upgrade must be used together.

Optimized launch control strategies

From the factory launch control is heavily regulated and limited resulting in a muddy launch as the transmission and engine fight to control torque. This is completely contrary to other DSG transmissions of the past and is a constant complaint on both tuned and stock vehicles as the factory method overlimits torque causing slow launches and slow 60-ft times. We’ve recalibrated the system to allow for a faster and more consistent launch, and ensured the clutches lock up to eliminate excessive clutch slip on the launch.

Optimized shift times

Shift timers are optimized to deliver the fastest possible shifts allowable by the transmission. Furthermore, artificial delays between requesting a manual shift and receiving one have been reduced as much as possible.


Find your boxcode and revision


Performance notes: When updating the TCU, always check for and update to the latest ECU version, if available. We have only validated our TCU upgrades while using our ECU upgrades. When not using both in combination, various behaviors and features may not be predictable or as described. To get maximum torque/power, run the TCU with normal or high torque ECU files (not the low torque files). Compatibility notes: Most vehicles with a build date of 01/2022+ are not currently compatible due to a locked TCU. Please Note: Each vehicle's year, make, and model may have multiple factory engine or transmission controller software part numbers, known as box codes, each with unique revisions. Manufacturers periodically release software updates that alter this information, which can only be determined by scanning the controller and is not publicly provided. Due to the variety of codes, some stages, octane levels, features, or options may not be available for specific codes. Therefore, our website provides a general guide based on general info such as Year, Make, and Model. Our system allows you to request unavailable software, and we offer a 30-day money-back guarantee if you're not satisfied.
