Just ordered the full service manual. It's a long shot, but I will let you know when I get it.

Do either of you have the Original Bimota owners manual for the bike? Often the wiring diagram is in the back of this in a fold out section...and not contained in the Workshop manual...they chopped and changed between models...but its normally only in ONE of them...and not BOTH...You'll also have to learn to translate the colour scheme of the wiring diagram from Italian to English...as all the coloured abbreviations are in Italian...I translated these and posted them up on here, into English...I'll dig it out if you wish

Just got the full service manual and it has nothing for the ECU circuits. It does have the wiring diagram but nothing circuit wise other than the TPS ohm readings. Previous owner of my bike gave up nothing but the bike when I bought it.

If you have good power and ground along with a signal from the crank and camshaft sensor, the ecu is bad. I have repaired a couple of them for that same problem if you need to get it repaired.

Got the ECU back at last new chips fitted and now sparks and purges fuel pump should be back on the road this year.
Not used because of this fault for last 6 yrs.
Amused myself on my DB9 for 18 months and that needs sorting over the winter.
So thanks for the help .
