    • Eurocode introduces TVS DSG tuning (TCU) Software - DL501, DQ500, DQ381, DQ250, DQ200 - Flash your car at home!

      Last month BoostAddict posted an article regarding TVS Engineering DSG software and frankly the capability seemed too good to be true. These guys have tuning (and clutch upgrade options) for basically every VW/Audi DSG gearbox and are able to display some very, very impressive software control.


      The problem for US Audi and Volkswagen enthusiasts was getting this software as TVS engineering is located in the Netherlands. Well, Eurocode Tuning in the USA (Torrance, California) is distributing the TVS DSG software in the USA and will be the source for your Audi/VW TVS dual clutch transmission upgrades.

      Eurocode covers the transmissions, upgrades, and specifications below.



      Eurocode Tuning is excited to announce that we are a distribution partner for TVS Engineering products, offering their wide range of DSG software upgrades for DL501, DQ500, DQ381, DQ250, and DQ200 gearboxes.

      TVS Engineering, through their personal flasher, allows the consumer to install their Drivability Upgrade, Stage 1, Stage 2 and Stage 2+ Upgrades in the comfort of your own garage!

      Stage 3 and Stage 4 TVS Engineering software upgrades are available at authorized service locations.

      The detailed information regarding each gearbox variant may be found below.



      With a stock of 1,000 DSG gearboxes and an annual repair of around 2,000 DSG's, TVS is the world's only true DSG specialist.

      TVS-Engineering is well represented outside the Netherlands by over a hundred dealers worldwide, from Singapore to Brazil. Eurocode Tuning represents the North America market.

      At the moment, about twenty employees work at the HQ in Varsseveld (the Netherlands), performing repairs plus software & hardware engineering.

      TVS customers are mostly business customers such as VAG dealers, ANWB, Taxi- and leasing companies as well as large national and international (tuning) organizations such as Eurocode.

      What makes TVS-Engineering unique is that is has been offering innovative next-level solutions on DSG software since 2005. TVS also specializes in less complex automatic transmissions such as the CVT (Audi) and the 09G/09K 6-speed automatic transmission, mainly seen on VAG vehicles.






      Known issues that this software takes care of are the excessive slip on the clutch in 2nd gear, the low rpm shifting as well as the slow reaction time while accelerating.

      TVS Drivability Upgrade:

      • Optimized D mode shifting program
      • Optimized S mode shifting program
      • 1st gear activations (on request)
      • Smoother gear changes.


      Issues Addressed:

      POOR SHIFTING STRATEGY: When entering a curve or roundabout the DSG has the wrong gear selected. This creates a poor throttle response when accelerating out. This happens when the turbo is not matching with the DSG shifting program.

      UNDER REVVING: The DSG up-shifts at extremely low rpm's. Generally, when you are driving at 80km/h the DSG is already in 7th gear and at about 1150 rpm. When given a slight throttle the engine and gears start making audible vibration sounds. These sounds will become more noticeable over time if not fixed and will result in permanent flywheel damage. We can fix this problem by raising the shifting rpm values and so reduce the frequent up and down-shifts. The gear shifts can even be customized to individual requests. The engine and DSG transmission will respond better and faster when applying throttle. Our unique software also has protective capabilities to reduce the commonly occurring problems which will result in damages to the clutch and gearbox. The repair costs would be a multiple of the costs of software modification. With a simple and affordable software package, we give you a solution to help your DSG have a longer life with better performance.

      SPORTS MODE: The majority of drivers find that the DSG is S mode does not drive very well. The DSG down-shifts too early and you will get a high engine revving noise. It also increases fuel consumption. What we can do for you is to customize the S mode so that it is more suitable for driving in the city.

      MAXIMUM RPM: The engine REV limit at full throttle goes up to as high as 4700 RPM. By doing this, the car accelerates faster and of course, the lifespan of the engine and turbo will increase.

      For these top models, TVS Engineering has developed special software for both the transmission gear shifting improvement and the integration of extra unique function for these models.

      Examples:

      Torque limit increase

      • Clutch clamp force increased to 800 Nm
      • Max shifting RPM increased to 8500 RPM
      • Special Launch Control Function
      • Increased gear shifting speeds


      Max Torque Numbers:

      Stage 1: 600nm
      Stage 2: 700nm
      Stage 2+: 700nm
      Stage 3: 800nm
      Stage 4: 1000nm (TVS DQ500 Racing Clutch Upgrade required)






      Known issues that this software takes care of are poor shifting strategies, shifting at extremely low rpm's, and slow reaction when accelerating.
      With this single and affordable software package, we give you a solution to help your DSG have a longer lifetime and improved drivability.

      TVS Drivability Upgrade: (comes with any stage 2+ and above software)

      • Optimized D mode shift program for ultra smooth shifting
      • Optimized S mode shift program for ultra smooth shifting
      • De- or reactivation of the 1st gear (optional)
      • Increased shifting speed
      • Improved clutch cooling and thermal management


      Examples Of Driveability Problems


      POOR GEAR SHIFTS: When entering a roundabout, the DSG has the wrong gear selected resulting in poor throttle response when accelerating. This is caused by a DSG shift program which is not matching the engine. TVS developed unique shifting strategies for any application.

      UNDER REVVING: The DSG up-shifts at extremely low rpm's. Generally, when you are driving 40-60 km/h the DSG runs already in its 6th gear at about 1100 RPM. When giving slight throttle the engine and gears start making audible vibration sounds. These sound will become more noticeable over time and will result in permanent flywheel damage. We can fix these problems by raising the shifting rpm's. Our unique software also has protective capabilities to reduce the frequently occurring DSG problems which will result in damages to the clutches and gearbox.

      SPORTS MODE: The majority of the drivers experience drivability problems in Sports mode. The down-shift rpm's are often too low or sometimes too high. We fully customize the S mode so that it matches the engine power output and driver requirements.

      MAXIMUM RPM: The maximum rpm is determined based on the power output of the engine to achieve the fastest performance while keeping drivability smooth. By doing this, the car accelerates faster and of course, the lifespan of the engine and turbo will last longer.

      Max Torque Numbers:

      Stage 1: 500nm
      Stage 2: 600nm
      Stage 2+: 600nm
      Stage 3: 700nm
      Stage 4: 850nm






      The DL501 is the strongest S-Tronic (DSG) gearbox on the market. Audi designed this gearbox to handle up to 1000Nm of torque at an engine speed of 10.000 rpm. Despite this, DL501 has a lot of issues, especially those produced between 2009 and 2013. The issues are fixable, after some modifications, your gearbox should be problem free.

      Some unsolvable complaints can be fixed with the use of unique software from TVS-Engineering.

      The DL501 can handle up to 1000hp and 1000Nm. (With TVS/DSG software)

      For these top models, TVS Engineering has developed a special software. Not only is the transmission gear shifting improved but we also integrate extra unique functions for these models. TVS programs all S-Tronic models. Since 2013, we are the first to program the S4/S5 Generation II.

      Known Issues and Symptoms:

      • Q5 2.0 TDI: Extremely low rpm gear shifting. (Droning)
      • Q5 2.0 TSI: Incorrect gear selected
      • All models: Long delay response from the steering wheel shift paddles (except S4/S5)
      • All models: Strong jerk when down-shifting from 2nd -> 1st gear
      • All models with higher mileage: Knocks when down-shifting
      • Flash of the warning light


      TVS Software Pack Contains:

      • Optimized D mode shifting programming
      • Optimized S mode shifting programming
      • Elimination of shocking shift behavior
      • Improved shifting speed


      The TVS-Software does not have any negative effects on fuel consumption.

      For more sporty drivers we can also offer:

      • Launch control integration (not delivered ex-works)
      • Improved response time of the steering wheel shift paddles
      • Clutch pressure to hold up to 800Nm is possible (Unique, worldwide)
      • Increased torque limiter


      5 Examples Of Issues:


      POOR GEAR SHIFTS: 2.0L ENGINES When entering into a roundabout, the DSG has the wrong gear selected. This creates a poor throttle response when accelerating out. This happens when the turbo is not matching with the DSG shift programming.

      UNDER REVVING: 2.0 TDI The gear shifts at extremely low rpm speeds. Most of the times the DSG software when you are driving at 65km/h it is already in the 7th gear and about 1150 RPM. When you give it slight throttle at low RPM you will hear the engine and transmission start making vibration sounds as well as the flywheel making noises. This sound will become more noticeable over time if not fixed and will result in permanent damage to the flywheel. We can fix this problem: By raising the RPM values we can reduce the frequent up-shifts and down-shifts. The gear shifting speeds can even be customized to an individual request. The engine and DSG transmission will respond better and faster at the throttle. Our unique software also has protective capabilities to reduce the common recurring problems that could result in damages to the clutches and gearbox.

      SPORT MODE: The majority of the drivers find that the DSG in S mode does not drive very well. The DSG down-shifts too early which causes a high engine revving noise and also high fuel consumption. What we can do for you is to customize the S mode so that it is less aggressive or, if you wish, more usable for pulling a trailer or caravan.

      MAXIMUM RPM: TDI The Engine REV limit at full throttle goes up to as high as 4700 RPM (Depending on software versions). We limit this to about 3700-4000 RPM. Effectively the car accelerates faster and of course, the lifespan of the engine and the turbo will last longer.

      ALL MODELS WITH HIGHER MILEAGE: The Quattro-Drive slowly gets more and more backlash in the gears. The propeller shaft and rear differential also get more backlash. As a result, the transmission occasionally pounds at alternating gear (e.g. during Down-shifting). For cars with these problems, we have developed a special software version. (Unique, worldwide)
