Mechatronic

The DSG gearbox has many sensors. All of these sensors go to the Mechatronic to process the signals supplied. The electronic/hydraulic control is provided by the mechatronic. The mechatronic control unit. The Mechatronic is the computer of the DSG gearbox. Here all data is sent to. Each sensor that you can think of is going to the Mechatronic. This unit is controlled both electrically and hydraulically. The mechatronic controls and operates the clutch for you, it is important that the software and valve body have no malfunction.

Which VAG DSG gearboxes do we adjust?

The DSG gearboxes that we software wise customize include:
 
  • DQ200 7-speed gearbox with dry clutch (also the MQB).
  • DQ250 6-speed gearbox with wet clutch (also the MQB).
  • DQ500 7-speed gearbox with wet clutch.
  • DL501 7-speed gearbox with electro-hydraulically controlled twin clutch.
  • DQ400e 6-speed gearbox with wet clutch (including the MQB).
  • DQ200e 7-speed gearbox with dry clutch (including the MQB).
  • DQ511 10-speed gearbox with wet clutch in the future.
  • DQ380 7-speed gearbox with wet clutch in the future.

DSG 'Stage One' tuning

The basic tuning (stage 1) includes increasing of the torque limiter in the DSG software, along with the increase of the switching pressure. We also remove the "kick down" in manual mode. After all, if the accelerator pedal is pressed down the DSG switches unnecessary back before the car starts finally accelerating. For diesel cars with much torque this is unnecessary, even undesirable, and it is better to remain in the same gear.

Strange enough the DSG gearbox activates the kick down in the original software, even though manual mode is selected. The gearbox will also automatically shift up, even in manual mode, by a fixed speed limiter. By adjusting the DSG software, the gearbox will in manual mode not be upshifting but the engine limiter will be used instead. By adjusting both the kickdown and speed limiter, the car becomes ideal for people who like really raw speed. Now it does not matter anymore if you drive on the track or on the German Autobahn.

Maximum RPM

But that's not all. We also remove the automatic upshift at maximum RPM. With petrol engines we will increase the maximum RPM and with diesel engines we're just going to lower the maximum RPM. Why? Simple. It is known that the transmission in the original DSG software configuration will upshift at 6800 rpm. That is no problem for a standard car of course, but models with a larger turbo would like to continue for a while to speed up with much higher RPM’s. If desired, we therefore increase the RPM.

Also with diesel engines, we provide improvement. As everyone knows, with modern diesel engines the gearbox will only shift up between the 4.800 and 5.000 RPM. That's a shame because the maximum power of a diesel engine is around 4.000 RPM. So it is prudent to reduce the maximum RPM for the diesel (except in high gear, of course). This prevents the vehicle is useless pulling in high RPM, but the engine remains better in its optimum operating range. This is not only better for the driving and the driving experience, but can also save
much on fuel.

Problems with the DSG gearbox
 
  • Vibrations when switching
     
When the car vibrates during acceleration or when switching from 1 to 2 then the DSG gearbox is likely damaged. We can reduce this in the software, fix and prevent it.
 
  • Engine lagging.

If you drive slowly and want to accelerate instantly the car reacts badly. If you give too much throttle so the gearbox downshifts and the car will rocket forward. In most cases this is due to clutch wear. Through software, we can fix this so that the car reacts smoothly.
 
  • Vibrations while under-revving
 
Many DSG gearboxes have software versions whereby you are already in the 7th gear from about 58 km/h and 1.200 rpm. When you accelerate a bit the engine and gearbox vibrate because of under-revving. We can resolve this problem by adjusting the RPM’s higher.
 
  • Sport mode exaggeration
     
For many people with a DSG gearbox, the "S" program too exaggerated. The car makes too much engine noise and consumes more fuel because the shift down is too early. We can adapt the “S” program so that it is less intense. After the adjustment, the program is more suitable for city traffic, or to drive sporty.
 
  • Unwanted kickdown
     
If the accelerator pedal is pressed the DSG downshifts unnecessary. The gearbox downshifts  first before the car accelerates. For diesel cars with much torque it is unnecessary and it is better to remain in the same gear. This is a common problem and we can easily adjust the software for you.

Benefits and the solution with DSG tuning

Each gearbox has various possibilities to optimize the DSG. For instance we can customize the D + S program, adjust RPM’s to your liking and reduce unwanted downshifting.
 
  • Increase torque
  • Remove torque limiter
  • Improve switching time (± 20 ms)
  • Increase maximum switching RPM’s
  • Launch Control RPM adjustment
