Admittedly, I'm new to the world of Guzzi, and to EFI motorcycles, but why is this industry so many lightyears behind the automotive industry in terms of closed-loop control? Is the relatively small size of the motorcycle engine the issue? Certainly it's not the lazy state of tune of motorcycle engines! The issues of performance and economy seem to beg for a closed-loop system, so why is it that even the BIG Japanese makers are not there yet? Surely Honda, at least, could readily import the technology across the street from the cage division!
It seems that even the aftermarket motorcycle EFI industry is simply a matter of providing a platform for messing with the A/F map of an open loop system, and perhaps the spark. A basic piggy-back box might quite easily close the loop, and even add multi-sensor parameter tracking for the enthusiast.
What's up in this industry?
