Alientech KESS3 – The next generation of tuning tools

The KESS3 is the latest ECU tuning tool from Alientech that replaces both the KESSv2 and K-TAG.

KESS3 gives you more control than its predecessors, KESSv2 and K-TAG, and can be upgraded without the need to spend money on new hardware. This new tool allows users to remap in a faster, easier way than ever before, with the ability to use both OBD or Bench Tuning methods from the same device.

The KESS 3 tool is the latest step in ECU tuning, which is faster and more powerful than its predecessors.

Here are the 6 top highlights…

1. You no longer need separate tools for OBD and Bench Tuning.  With the new KESS3, this is now a combined feature.

2. Greater choice and granularity with new Protocols Packs:

– Car – LCV

– Bike – ATV & UTV

– Agriculture – Truck & Buses

– Marine & PWC

3. Lightning quick reads and writes with advanced processing speeds, means  Warp speed checksum calculations.

4. KESS V2 Cables are transferable – no need to  buy new cable sets

5. Bench and Boot protocols are now available to purchase individually

6. Service mode – greater coverage; no need to open the ECU to perform bench tuning anymore on a greater selection of ECU types

How it works

The Kess3 tool is connected to the vehicle’s OBD port or to the ecu directly and the original ECU map file is copied and stored on to the tool. This map file is then sent to our HQ via your dedicated dealer portal for modification, you can stipulate the type of modification you require. i.e. Stage 1 or Stage 2 Remap, EGR Delete, DPF Removal, SCR Delete … etc …….
Within 1 hour (normally much less) the modified map file will be complete and ready to download to the New Genius tool, this modified ECU map file is now ready to be programmed back to the vehicle via the OBD port.
