Save £200! When you purchase ECU and TCU software together.

The DQ381 gearbox was released into Volkswagen AG passenger vehicles back in 2017. The 7-speed dual-clutch gearbox (0GC) was derived from the advanced development of the previous 7-speed gearboxes, such as the DQ380 (ODE) and DQ500 (0BT), which had been used in commercial vehicles from 2010 and passenger vehicles since 2011. One key feature of the DQ381 gearbox was principally aimed at increasing efficiency. Unlike the DQ380 gearbox, the DQ381 was designed to be used in both FWD and all-wheel drive vehicles on the MQB chassis platform, such as the Mk7 Golf GTI and R, Audi S3, Tiguan and Arteon.

This 7-speed wet clutch gearbox is already an improvement over the previous DQ250 6-speed, in terms of allowing the vehicle to shift more efficiently, and with a smother gearchange due to the closer gear ratios. However, driving a DQ381 equipped vehicle you will know that there are still areas that can be improved, especially on performance modes. With the stock calibration, you may find that gear shifts happen too low in the RPM range, or too high when in sports mode. These can lead to unsmooth driving, or make the vehicle feel too aggressive. You may have also experienced clutch slip when running performance ECU Software.

IT’S ALL ABOUT THE DRIVE

Revo DQ381 TCU software has been designed for the driven. Working on the characteristics of the gearbox to provide a better driving experience and optimal performance when coupled with our performance ECU software. Holding the gears better in sports mode so it’s not changing up early and allows the engine to be in the right power band more of the time.

Revo TCU Software gives you much more than just increased clamping pressure and quicker shifts. A large part of development is based on driving scenarios and feedback, ensuring an exhilarating experience. Expect smooth and refined response at low RPM & partial throttle, with optimal shift programming for wide-open throttle driving.

Driveability

Revo TCU software has been designed alongside our ECU software to not only improve performance but to enhance the feel and driveability of your vehicle. This was the key focus during development, and something that takes time and thousands of miles to achieve. When vehicles are equipped with an Eco/Efficiency drive mode, this uses unique mapping and remains as “stock” to keep all the characteristics. To ensure low RPM driveability, whilst in traffic for example, when you are below 30% throttle input the software will replicate the feel of the stock software. But when required, put the car in Sport/Cupra drive modes, and the gearbox in Drive or Sport and you will be treated to a much-improved sportier feel.

Progressive Software

As we produce all our ECU and TCU software in house and have access to vehicles through our global network of authorised Dealers, we have been able to test and refine the software for all ECU stages. This means that our “Progressive TCU” software will work with Stage1 to Stage 3 ECU software on 2.0 TSI DQ381 vehicles. You can install Revo TCU software when at Stage 1 ECU, and it will cover you as you progress through the ECU stages without the need to change TCU software.

Shifting

Gearshift points in gearbox D and S modes have been enhanced and matched with Revo ECU Software. Meaning each gear shift will be at the optimal point to give the best possible performance and fastest acceleration. The shifting times have also been improved and made quicker in D, S and S manual modes. Tested on Stage 2 Audi S3 8V we saw an improvement of up to 0.4s on the 0-60mph time from launch over the stock TCU calibration. The 3-step launch control RPM limits have been optimised to offer 3 different RPM points depending on the throttle input 10-30% launches at 2200rpm, 45-79% launches at 3600rpm and over 80% launches at 4250rpm. When at partial throttle, the gearbox isn’t always looking for the highest gear, it holds the current gear longer. Keeping the turbo spooled and the vehicle within the right power band, thus not changing up and down the gears at much and therefore offering a smoother and more enjoyable drive.
