Alientech - KTAG

ECU Bench Programmer

K-TAG is the most complete and professional tool to read, write and clone an ECU or TCU on any vehicle.

K-TAG communicates with all ECUs, even the latest generation ones. You can read and write directly to the ECU microprocessor, the flash memory and the EEPROM, without opening the ECU!

Recalibrate, Repair, Clone. Do more with K-TAG!

With K-TAG you can get to the heart of the ECU, have access to all the necessary data to operate safely and efficiently on the vehicle.

The Bootmode modality allows you to read and write, with an open ECU, the deeper parts, by simply connecting the tool to the electronic board of the ECU.

Thanks to the Service Mode, recalibrations, repairing, and cloning have become simple operations. You don’t have to open the ECU, thereby reducing the margin for error whilst increasing your results to the maximum!

Reliable, Professional.

K-TAG is the tool for professionals, designed and built by professionals. Every business need is met by working efficiently and precisely on cars, motorcycles, trucks, tractors, and boats.

It provides you with complete access to the ECU and the TCU to read and write the microprocessor, the EEPROM and the flash memory. With K-TAG you can also carry out advanced modifications, backup operations and “cloning” of the ECU.

The perfect choice for an expert professional, who requires a reliable tool, that is safe and highly professional.

There is no Slave without Master.


After reading the remapping file in the ECU by using K-TAG, you can modify its operating parameters with ECM Titanium software to the specifics requested by your customer. Then rewrite it later in the ECU.


Thanks to K-TAG you can program the ECU with the files sent directly to you from your Master within a few minutes. You can select your Master from the professional’s network, certified by the Alientech Academy. Engine remapping with zero risk and positive results.

A professional who decides to start with a Slave system can choose, with the right training and experience, to switch to the Master system at any time they wish.

Specifics and Functions


Designer for K-Suite 3 and more! A single management software to remap ECUS and TCUS, to manage your tools, protocols, and activations.

RD, WR, Clone.

Real reading and writing, and cloning. Bootmode, Service Mode. Each function available brings you to the result you want to achieve both safely and efficiently.

Checksum Check

This is an operation that verifies the ECU data integrity. The checksum correction is carried out by K-TAG on each file during the writing process, to ensure normal operation of the ECU itself.


With the Recovery function you can restore the communication with the vehicle and restore the file read from the ECU, or rewrite the modified file, thus recovering the full functionality of the vehicle.
