As per title really, you know like many Ferrari V8s, BMW V12s, etc etc that run 1 ECU per bank of cyls.

Are they mappable live? I mean you got twice as much to do, havent you?

Or can you pretty much double up the info from one side to the other?

How do they pick up crank sensor readings too? I guess just 2 crank sensors opposite each other?

I was just reading about it and it got me thinking, which is never good, as it bugs me till I know the answer
