KESS3 Frequently Asked Questions

1. How can I interface and program the control units?

With KESS3 you can program the engine control units (ECU) or transmission control unit (TCU) in three different ways:

OBD – With the OBD mode, you can easily access all the ECU data through the diagnostic socket.

BENCH – With the Bench mode you can access the ECU data directly from the connector

BOOT – With Boot mode, with the engine control unit opened, you could connect directly to all the memories of ECU/TCU.

2. What is the difference between Master and Slave?

As a Master user, you can read the files in clear. This allows you to operate independently in order to remap and reprogram the ECU with modified files. As a slave user, only your master will be able to decrypt your files. (Recommended choice for taking the first steps in chiptuning, supported by your Master)
