Here is the map from my bike. The bike is stock and has an LC1 lambda sensor. It runs closed loop.
This map is a result of many autotune rides and also logging for later analysis.

Many users receive this as their starting pointing.

There's normally no reason for a Guzzi to have different characteristics between left and right cylinder, as they get equal cooling and have (damn near) identical exhausts lengths and so on.

A Ducati will have much worse cooling for the rear cylinder, and if that is mitigated with water cooling it still applies for the exhaust temperatures (quicker cooling in the exhaust pipe affects back pressure and will affect the tune, academically or not). Also, a Ducati will never have identical exhausts. Even if the lengths are equal due to some extra bends on the rear one, they are still not the same.

My stock WM ECU do have some offsets though. There's no pattern - some are plus, some are minus. I don't regard them as being of any value.

If I ever get back to working on my Sport 1100i, are there any maps for engines that have been ported and dual-plugged?
