Right bud, i clicked on Connect any tacho, and it scanned 2 sort of 'channels', thats the best way i can describe it, over and over, possibly 9600 and 1400 or something like that.
When i got bored of watching that, and tried to connect to VDO new just to see it not work, i went back on the 'connect any tacho' and it seemed to scan the same 2 again.
Its an IMMO 2 bora sport cluster with part numbers that match up to a part number on a thread by old_no7.
