OBD Tuning Tool - KESS 3

Alientech Kess 3

OBD Read and Write

KESS 3 is an easy to use OBD programmer for engine ECUs and gearbox TCUs. KESS 3 has the widest coverage of any tool on the market with its user-friendly software.

Thousands of Vehicles

KESS 3 is compatible with all brands and can be used for cars, bikes, trucks, tractors and boats! There’s a continues flow of updates to support new vehicle releases so you’re never left behind.

Slave vs Master

The only difference between KESS 3 slave and KESS 3 master is the ability to access and edit the data read from the ECU.

Master KESS 3 The master tool reads decrypted files allowing any user to edit the file read from the ECUs and write it back to the ECU.

Slave KESS 3 The slave tool reads encrypted files allowing only one tuner; in this case its master file supplier to edit the files.

Specifics and Functions

Designed for Alientech Suite and more! A single management software to remap ECUS and TCUS, managing your tools, protocols, and activations.

Checksum control

An operation that serves to verify the integrity of the ECU data. The checksum correction is carried out by KESSv 3 on each file during the writing phase, to ensure the correct operation of the ECU.

Recovery

With the Recovery function, the connection with the vehicle can be restored and the file read from the ECU can be recovered, or rewrite the modified file, thus recovering the full functionality of the vehicle.
