Per my several notes regarding limp home mode and suspected failed DME.... Today I received a new, used DME purchased through I had also sent the Conforti chip back to Turner for a diagnostic check to make sure it was OK.

The chip checked out OK so I installed it and the new DME tonight and voila, smooth running V12!

I'll reserve some hoopla for when I've had a chance to really drive over bumpy roads, etc. but for now, I think I've got the problem licked.

Finally, the new, used DME (actually labeled MOTRONIC) came with a DINAN chip. It's Model D900-5033. I only have the one, but if anyone needs it for a spare to match their set, let me know and I'll send it.
