Hello,
Is it possible to get the KTAG or Kess connection protocol for a Bosch MEDC 17.9 Land Rover ECU?
When I use KTAG, I don't see MEDC 17.9, but if I go to (Options/Available Vehicles/Kess), I see MEDC 17.9 via OBD.
Now, if I select KESS for OBD, I don’t see MEDC17.9. Similarly, when I go to (Option / Available Vehicles / KTAG), I see MEDC 17.9.
It seems like the protocols are reversed.
I updated both SD cards, but nothing changed (KESS 5017 microSD / KTAG7020).
Please help.
