The Giulietta is one of the most popular Alfa Romeo vehicles: an excellent concentration of practicality and good performance. What could make it perfect? Simple, better performance!

This course will teach you the practical procedure to increase the performance of the Giulietta JTDm2 engine thanks to a simple tuning of the engine control unit. The Alientech technicians have developed a remapping procedure that allows you to increase the values of maximum torque and power without decreasing the reliability of the vehicle or damaging the mechanical parts. In just 30 minutes, you will be able to learn all the information you need to know before the tuning phase, then you will follow the modification procedure on our ECM Titanium software and you will evaluate the increase in performance and diagnostic results after writing the modified file. All this at an affordable price!

Not only will you be able to apply this practice to all the Alfa Romeo Giulietta cars in circulation, but also to the other FCA and Opel vehicles equipped with the same engine and control unit models considered here. And that’s not all: both beginners and more experienced tuners can benefit from the information contained in the course. The former can easily obtain the results guaranteed by Alientech technicians, the latter will be able to use the modifications and information provided as a starting point for their own custom tuning.

One lesson of about 30 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.
