APR's TCU Upgrade dramatically improves upon the transmission's function, drivability, and performance through a myriad of enhancement and custom features. Normal daily driving is smoother as we've improved upon the normal quirks and complaints associated with the driving experience. Sporty driving is far more capable with increased torque capacity, clamping pressure, torque management during shifts, AMAX in all gears, and optimized shift point! Both scenarios are optimized to deliver faster acceleration by matching the power output delivered by our ECU Upgrades. Lastly, the software loads to the factory TCU through the OBD-II port, resulting in a clean and headache-free install.

Features:

  • Faster up and down shifts in all modes
  • Optimized shift points for faster acceleration and smoother driving
  • Shift points for both stock and big turbo setups (B9 S4/S5/SQ5) at no additional charge
  • Increased maximum allowable torque for higher output
  • Increased clutch clamping pressure to hold more torque
  • Optimized torque management during shifts for smoother and stronger shifts
  • AMAX maximum acceleration shifting mode enabled on all gear shifts
  • Manual mode auto 1-2 shift disabled
  • Increased maximum RPM on big turbo software (B9 S4/S5/SQ5)
  • Works perfectly with our ECU Upgrades
  • Flash counter does not increase with each flash
  • Direct OBDII port flash (No TCU removal)
  • Free lifetime updates
  • 30 day money back guarantee

This part is legal under the provisions of EPA’s Tampering Policy dated November 23rd, 2020. The company has reasonable basis (test results) to verify that this product allows the vehicle to operate within legal emissions standards and is therefore legal to be sold for on-street use in all states that accept the legal provisions of the Clean Air Act and the EPA Tampering Policy. This product is NOT LEGAL FOR SALE OR USE IN THE STATE OF CALIFORNIA. Testing with the California Air Resources Board, in order to achieve 50-state compliance, is pending with CARB. Once testing is complete with California, and an E.O. number is issued, this product will be updated to 50-state legal status.
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. Compatibility notes: Most 2023+ model year vehicles are not currently compatible due to a locked TCU.
