W124 CANbus?
I am the proud new owner of a 1995 E320 Wagon
Always wanted one.
Smooth ride @ 327.xxx miles, newly replaced wire harness, new front bumper (not yet installed) trans slipping a little but nothing that I cannot handle especially for $350.00. See pics.
I do have an engine and few transmissions laying around (including a 722.6), just have to make time to swap it out.
Which lead me to ask a question.
I know that the 722.6 transmission require CANbus for the TCU. Twisted green and white wires, I noticed that the ECU in the W124 has these wires.
So I visited a local junkyard earlier today and got curious and raided a W210 12/95 model; and it carried what seemed to be the same pinout arrangement as the W124 ECU.
The question is, do they W124 broadcast CAN and if so, is it usable for the 722.6 TCU and or, might these ECU's be interchangeable?

I have read that its a drop in installation since the TCU does all the shifting...and can even be tuned. You can also add paddle shifting. There is a company that sells the electronics for retrofits.

They both use the CAN to send and receive instructions, however the problem is that the software could be different, if they are, they are not interchangeable--use a diagnostic tool to help you define the software version---or spend more time with the family vs running around to junk yards!

Any other suggestions Plutoe? Maybe I'll get a few more.

If all fails I'll simply Megasquirt the thing because it would broadcast CAN signals I'm looking for.
