One lesson of about 60 minutes, composed by 3 sections:


First section:

in this part 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 remapping practice, 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.
