Thats why I said "when its available", and we both know there is not an OE solution for aircooled that would work on a big displacement aircooled enigne.
I'm guessing you and Mike have your EFI dialed in better than just about anyone. You understand first hand just why it isn't feasible in a production sense as it takes a ton of time, patience, skill, testing, retesting, retesting again etc... and there isn't a universal solution so having it done and dialed in once doesn't mean you don't have to start from scratch to do it again.
I have a local client with CB Gen 4 that we played with, and dialed in, for nearly 2 years before we were remotely happy with it, and much of that was for good idle stabilization. You can't touch the throttle for about 2-3 minutes after initial start or it dies, no matter what we do, but that is just one of the idiosyncrasies of it all, he knows it, and it forces a little oil temp into things before you take off which isn't a bad thing. Other than that it has been a dream for 7-8 years.
