Here's one for the experts...trying to solve lumpy running on my newly acquired Breva today, and my mate's diagnostic software couldn't connect to the ECU. Looking more closely at trhe ECU itself, this is what we found. It looks like it came from a Model Year 2003 Californian...should that really be fitted to a 2006 Breva?? BreavaEMS
 
A 15RC is the correct ECU for a 750 Breva, but you need one for the Breva. Looks like you have the wrong ECU. I believe this is what you should probably have.

Here is the confusion. Guzzi has two Brevas, one is the 750, the other the 1100. The 750 uses the 15RC, the 1100 the 5AM. When anyone states they have a Breva, they should also include the displacement. BTW, there is no way to hook up a 15RC to the 1100 Breva. Completely different connections to the ECU.
