I'm in the midst of swapping a C series ecu(GEMS / 2wheel TC) for a D series ecu (Bosch / 4 wheel tc).
The C series has a K and an L line running directly to the OBD plug, whereas the D series ecu only has one line going to the OBD plug.
I'm a bit confused, as I though this was RS232 and as such needed a clock line, and a communication line.... my understanding of this is sketchy as you can no doubt see.
I'm wondering if I put the D series ecu in my GEMS p38, (wiring in the D series ecu with only the one line as per the ETM), will diagnostics such as Hawkeye, Faultmate (with the D series module loaded of course) still work as to normal?
Thanks in advance.
