Kess v2 ECU programmer master chip tuning tool is everything you need to work as a successful tuner with coverage of all major brands and protocols including Line, CAN, EDC17 and MED17 and Ford J1850, without token limitation.

I had my own KESS V2 and used for my BMW E91 318D to read and write EDC17 C41 DDE8, while came with a problem. Here I express my operation process as below:

  1. With OBD connector – TOOL – OBD2DATA I can do, everything is OK.
  1. Boot loader with backup read – many communication problems -> Crash! After many attempts, I was able to read backup.
  1. With flash boot loader (ECU) read – many communication problems -> Abort, abort, abort! After many attempts, I was able to read original file but in the end came problem # 2 -> Checksum error.

I used computer with Windows XP SP2 operation system, Internet was always as KESS V2 was executed.

We attached picture below:

KESS V2 I bought on obdii365.com, so I turned to obd365 engineer aims to get a good feedback.

Solution:

KESS V2 can’t read and write this type of ECU, ECUs on the same car model in different areas are sometimes encrypted in different ways, and therefore the tool cannot always work on the same car model.
