That’s AutoTuner.

Reading and writing of engine control units and gearboxes

AutoTuner can read data from most of the ECUs and microcontrollers on the market.

Automatic Checksum correction

Checksum correction is done automatically by the tool during the writing process. There is no need to calculate the Checksum yourself.

Back to stock

Do you want to start from a sound and up-to-date base? Start by restoring the vehicle to its original state by using the “back to stock” function.

Live datalogging

The AutoTuner datalogging feature has been designed to be easy to use. For each supported ECU, we have pre-selected a set of relevant data depending on the vehicle and manufacturer's specific parameters.


Reading and deletion of Diagnostic Trouble Codes (DTC) that are generic and manufacturer-specific via the OBD-II socket.

All-in one package ready to use

In your AutoTuner case, your tool and its features are ready to go and are simply waiting on you to read their first ECU!



AutoTuner is already compatible with hundreds of units and thousands of vehicles. Does it end there? Not with us. We regularly offer new exclusive protocols.

ECUs 568

This method allows you to read off the data via the vehicle’s diagnostic socket.


This method requires disassembling and opening the engine ECU. The connection is made on the ECU printed circuit board (PCB).


This method requires only the disassembly of the ECU. The connection is made on the front socket of the ECU, so you do not need to open the ECU.

Free updates

Our goal? To carry on offering new protocols, updates and functionalities. And you can enjoy them right away.

Data Logging

You can't tune an engine without getting feedback on the modifications you just made. The information obtained during datalogging is vital in order to adjust the modified file as well as possible.
