Did you tune a vehicle’s ECU and didn’t get the increments you were hoping for? A common cause could be the automatic transmission! Let’s remove everything that holds your vehicle back from expressing its true potential…

This course, dedicated to the DSG DQ250 automatic transmission, allows you to learn how to take action on different parameters of the transmission control unit of your vehicle to achieve changes with different applications: increase the revs, increase the gear change speed, the power limiters, the Launch control and much more! Choose what changes to apply to your transmission and do it immediately!

The DSG DQ250 gearbox is installed on a vast number of vehicles within the Volkswagen group. Taking this course means having the possibility to work on many transmission control units, thus fulfilling all of your customers’ requests.

The changes that will be presented to you during the course have been studied by our Alientech technicians to allow you to unlock the limits imposed by the gearbox control unit, without, however, drastically increasing consumption or putting the efficiency and function of the transmission at risk.

The course is suitable for both beginners and more experienced tuners: choose what to modify, and use the course as a starting point for even more extreme maps!


One lesson of about 25 minutes, composed by 3 sections:

First section:

in this part of the course we will describe the characteristics of the vehicle by listing version, equipment, year of production, traction and type of gearbox. Then, we indicate all the vehicles – even of different car manufacturers – equipped with the same engine or similar version; immediately after, the specifications of the engine control unit will be specified in detail: that is the identification data and the versions for the emission classes. In addition, we talk about the types of connection with Alientech tools – which are useful for the remapping – by indicating the protocols of use, the available functions and giving some practical advice for editing operations. Finally, the structure of the original file is presented by indicating the addresses and the various areas.

Second section:

this part directly addresses the remapping practice. After a brief introduction, we present the summary list of the maps that will be modified, the Alientech modification method and its specific application to the vehicle in question. Following the wizard of this online course, you will be able to create a mapping that will ensure high performance and guaranteed reliability.

Third section:

this last part is dedicated to the discovery of the potentialities of this remapping practice: the new increases, compared to the original settings of the vehicle in a precise and detailed chart, clarify efficaciously how this remapping practice is effective and surprising.
