VW/AUDI Performance Parts: APR DQ250 DSG and S Tronic TCU Upgrade for VW Mk7 / Audi Mk3

Product Features & Benefits

APR is pleased to present the ultimate transmission control unit (TCU) upgrade for the DQ250 DSG and S Tronic transmission!

APR’s TCU Upgrades are the best modifications one can make to the DSG or S Tronic transmission. The upgrade allows the transmission to hold higher torque levels with faster acceleration and quicker shifts. Each driving mode is optimized for the higher power levels provided by APR’s engine upgrades. The upgrade allowing the end user to customize launch control and manual mode to their liking, and adds various features only found on higher end vehicles! When you pair this upgrade with an APR ECU tune, you are primed to get the most from your vehicle!

  • Faster Acceleration
    Increased clamping pressure, optimized shift points, and better launch control all result in faster acceleration.

  • Quicker Shifts
    Increased clamping pressure and optimized shift times results in a faster shift under various scenarios.

  • Optimized Shift Points
    Drive mode is optimized for fuel economy while sport mode is optimized for faster acceleration with APR’s various hardware and software upgrades.

  • Increased Clutch Clamping Pressure
    Increased clutch clamping pressure beyond factory torque levels to support higher output.

  • Smoother Daily Driving
    Optimized part throttle / daily driving shift maps to provide a smoother and more enjoyable driving experience.

  • User Definable 3-step Launch Control
    Launch control is enabled on all models, with ESP on or ESP off. Three user defined launch control RPMs are set at the time of install. Launch control response is also optimized for faster engagement and stronger take-off.
  • User Definable Manual Mode
    The automatic manual mode upshift and kick-down switch downshift can be enabled or disabled at the time of install.

  • Raised Torque Limiters
    Non-physical transmission torque limits are raised to allow for higher output while retaining critical protection limits.

  • Downshift Lockout Optimized
    Manual downshifts are permissible in all gears so long as the next gear is below redline.

  • Temperature Management Optimized
    Allows for limited torque during over-temp conditions vs total immovability.

  • Gear Display Activated
    Shows the current gear in the factory multi functional display in both drive and sport mode.

  • DirectPort Programming
    The TCU Upgrade installs in minutes without opening the TCU and can be uninstalled at any time.

 

APR’s Calibration Experts have recalibrated the transmission to continue increasing clamping pressure when clutch slip is detected. The transmission constantly monitors for clutch slippage, and adjusts clamping pressure such that the minimum amount of pressure is applied to prevent slip. This ensures clutch engagement remains comfortable under most driving scenarios. Unfortunately, this function is limited in its abilities. As such, clutch slip can occur when increasing torque. This often leads to overheating warnings, which are further exacerbated by low transmission fluid levels. APR’s TCU Upgrade reconfigures the clamping pressure routine to continue increasing clamping pressure to match the higher output from from APR’s various performance upgrades. Pressure steadily increases, preventing slip, but remains below maximum protection levels defined by the factory TCU.

On a healthy transmission, the result is easy to feel as it transforms the transmission. Expect crisper and faster shifts at wide-open-throttle, faster clutch engagement during take offs and launch control, higher max torque levels, more consistent back-to-back results, and faster acceleration!

Drive (eco) and Sport Mode

APR’s calibration experts found the factory drive and sport modes to be less than ideal when raising power above the factory limits. In drive mode, the transmission aggressively seeks sixth gear, earlier than necessary, leaving behind an anemic and lack luster experience for the driver. Likewise sport mode leaves a lot to be desired considering its seemingly exciting name. Under both modes, maximum shift points remain optimized for the factory power levels, which vary greatly to those produced using APR’s world-renowned catalog of performance hardware and software. As such, accelerative performance suffers due to non-optimized shift points.

To rectify this situation, APR’s engineers took a multi-step approach to custom tailoring the shift maps to sync harmoniously with APR’s performance upgrades and each platform’s gear-ratio configurations. While some may simply set wide-open-throttle, or WOT shift points to the vehicle’s max RPM limit, APR’s engineers chose shift points based on actual acceleration data. This result is gear dependent shift points typically below the engine’s max speed, but in doing so, the vehicle’s acceleration improves as axle torque is matched before and after shifts.

Under low-torque, low-rpm, part-throttle situations, both modes less aggressively seek the highest possible gear. Drive still has the benefit of economy, but stays within the power band more comfortably for a more enjoyable experience. Likewise sport mode has been optimized to provide a sporty feeling, worthy of its name. In both cases, the transmission seamlessly integrates with APR’s performance upgrades to provide an exciting driving experience.

Manual and Tiptronic Modes

APR’s user definable options allow the end user to configure how the transmission works while the gear selector is placed in manual mode.

The kick-down switch, which is responsible for an instant downshift, is enabled by default but can be disabled at the time of install. Likewise the auto upshift that occurs at the vehicle’s maximum engine speed can also be disabled at the time of install, allowing the engine to bounce off the limiter like a manual transmission.

The transmission does not lock out any manual downshifts so long as the shifting does not result in an engine RPM above the max shift point. In all situations, paddle delay is reduced, allowing for a more responsive shift to take place and furthermore, manual shift times have been optimized.

Launch Control

APR’s 3-Step launch control is unlike anything else in the market. At the time of flashing, the user chooses a maximum launching RPM. When activating launch control, up to three launching RPM’s are available, allowing the end user to choose the best launching RPM based on the current conditions!

At 100% throttle with the kick-down switch engaged, the vehicle will select the highest launching RPM. At 100% throttle with the kick-down switch not engaged, a lower launching RPM is activated. Finally, at roughly 50% throttle the transmission chooses the lowest launching RPM. When properly dialed in, the user is left with incrementally higher launch points ideal for the street, track and sticky tires.

Utilization of launch control results in the transmission entering the maximum acceleration mode. During this mode, intervention between a shift is minimized, resulting in faster acceleration that keeps the driver planted to the back of his or her seat. The delay typically present after lifting the brake and beginning of the physical launch has been improved for a more immediate response, while also physically speeding up the application of torque at the onset of the launch.

Launch control is enabled for use with ESP on or off, allowing the end user to experiment with launching techniques depending on tire setup, surface conditions, drivetrain and overall vehicle setup. ESP is most favorable on front wheel drive vehicles, especially in poor conditions, to help control wheel spin during a launch.  Furthermore, torque ramp rates were adjusted to help prevent excessive wheel spin, and subsequent first gear short shifting on all wheel drive vehicles.

The APR Way

APR DirectPort Programming:
APR’s DirectPort Programming is now available for the Temic Tricore DQ250 transmissions. Any APR Dealer in the world, connected to the Internet, has direct access to APR’s latest TCU upgrades for installation directly over the vehicle's OBD-II port. This completely eliminates the need to remove and open the TCU and can be uninstalled at any time!

APR TCU Upgrade Creation:
APR’s engineers have taken a direct and custom approach to calibrating the TCU. All too often others create a generic calibration that is forced across a wide range of different vehicles and transmission versions. Unfortunately this generic method of copy and paste tuning can result in some undesirable effects, such as slow up shifts and downshifts, torque interventions, stumbling, immobility and general incompatibility. In some extreme cases, damage to the transmission can occur. With many factory TCU variations available for the transmission, APR’s engineers have painstakingly ensured every TCU upgrade is created using the transmission’s original file to ensure the ultimate experience!

APR TCU Composer:
APR’s proprietary TCU Composer is used for altering the transmission management system. With full access to every table, map and variable within every TCU, APR’s Calibration Engineers are not limited to the handful of pre-defined maps.

APR TCU Assembly:
APR’s Electrical Engineers have the ability to alter the code structure of the TCU. Through code-level changes, APR's Engineers are able to add future features to the TCU otherwise impossible through calibration changes alone.
