Tuning example Bosch MED17.1.21 - VAG - 1.4l Hybrid

  • Description

The 1.4l TSI engine of the Golf VII GTE works in symbiosis with the electric motor and develops 150 kW of maximum power. The Volkswagen group equipped the same 1.4 TSI engine also on several Volkswagen and Audi hybrid vehicles.

This course aims to increase the performance of the combustion engine while maintaining the virtuous relationship with the electric motor unchanged: it is therefore a precious resource to maximize the collaboration between the two engines and to include a good number of hybrid vehicles in the possibilities of its own workshop!

  • Bosch MED17.1.21
  • 1.4 TSI
  • Volkswagen Golf VII GTE, petrol-electric hybrid, 2016


Would you like to improve the performance of a Volkswagen Golf VII GTE, but the hybrid engine worries you? No problem: Alientech technicians analyzed the characteristics of the Volkswagen 1.4l TSI combustion engine and developed a tuning procedure that doesn’t involve the hybrid plug-in engine!

Our standard tuning procedure, created over many years of experience in the field, was applied to the Golf VII GTE equipped with a Bosch MED17.1.21 control unit, thus creating a specific
procedure that guarantees both solid vehicle reliability and a good increase of performance, despite the automatic transmission with torque limitation.

Spend 20 minutes of your time taking this practice on the convenience of your pc and find out the other hybrid vehicles that are compatible with this kind of tuning procedure! Satisfy the needs of a greater pool of clients and start your own growth path!

This training not only involves a step-by-step tuning procedure, but it also includes a set of highly specific technical information, which is essential for a proper tuner’s career.

There won’t be any unpleasant surprises in the result: after remapping the Golf VII GTE, we tested the car on bench, and the results, shown in the last section of the example, are guaranteed!

Simple, effective and safe: what are you waiting for?


One lesson of about 20 minutes, composed by 3 sections:

  • vehicle, engine, control unit, connections and original file description
  • tuning procedure
  • diagnostics and results

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.
