Hi GPForverer2024!
Whoops! I've found a bug in in my scoreboard_to_revcounter util (It was the reason for the strange RPMs I was seeing when I'd set my revcounter cylinder switch to 3,5,6 or 8-cylinder).
I actually think my KET105 revcounter is a good bit of kit now. I've modified the big post I wrote on Sunday to paint it in a better light.
I'll upload a new MGPr package in the next few days that has the fix
