Kess v2 master or slave? original or clone?


It all depends. Kess v2 good clone used be ok for older ecus only, but now also work great with newer ones. and with a slave you will have to rely on the master for your maps whaere as if you have a master you can write your own or choose where you get them from.


Kess V2 or Ktag?

KESS V2 is a ECU programming tool that is perfect for OBD use, while KTag is perfect for Jtag, BDM and all the Boot application (tricore and ST10).


With KESS V2 you programming directly through the OBD port of the vehicle, while with Ktag you need to take apart the ECU and open it, after you can make the read/write operation.


Many ECU has the advantage that can be read and write from OBD port (so KESS V2 is perfect), but there are lot ECU that need to disassemble from the car and open and this is the case for all the ECU that need to be programmed with Jtag, BDM and Boot protocols, so KTAG is needed.
