Hi All,

by default I would say "NO it does not have CanBus". But I'm seeing in the docs that the TipTronic DME 5.2.2 Does have CanBus. I know that there are different ones for TipTronic(M249) vs 2.5L Manual, but my understanding of can bus is that all that would be needed to keep it the same in both would be a terminate the signal via a 20 ohm resistor between + and -. Why would Porsche need to have 2 different firmwares to manage? It makes me think maybe it's done that way internally and CanBus is available on pin 85 and 86.

Has anyone tried? (I'm sure it's wishful thinking, but I had to ask).

Cheers,
Pucky
