Bench cable or OBD cable, which for Kess V2 MB temic truck cables?
Any doubts about MB temic cables for Kess v2 tuning work? Bench cable or OBD cable?
There are some differences between the bench cable 144300K249 and the obd2 cable 144300K251:
You can not clone ecu from obd, for that you need bench cable.
Old boot cable works only on boot mode and does not support new continental ecu without flash memory.
So buy just two head (round + obd) Temic truck cable (with part number 144300K249). That is your choice for tuning.
This cable has been done on 200-300 MB trucks by a user, first in boot mode and after Kess v2 released OBD protocol.
Never had really any problems.
It’s easy to find with Google search seller from China sellers or other who sell euro clone Kess v2 or Ktag
But you have no this ecu tool now. Better to buy aKess v2 truck version. It is a truck specialized version. Compared with other kess in markets, this truck version adds a lot of ECUs for trucks diagnosis and ecu programming.
