* can you detail exactly what trigger setup are you thinking of ?

* if delaydeg += tooth_wheel_twidth; is used (and config.tooth_wheel_twidth properly configured) it should theoretically work with N+1 camsync setup, as long as teeth are evenly spaced and match the required ign timing difference between cyls.

* Eg a 4+1 trigger would work with 1,2 or 4 cyl even fire, but not with a V2 odd-fire Harley

* Must be tested of course.

* the ultimate solution would be to allow in configuration to artificially limit sparktooth, to always trigger from tooth0, or tooth0..1. With very low toothcount this often automagically holds. But it could be useful in MembersPage/FiatStilo style (eg. subaru) triggers as well.

** and maybe limit dwell to same tooth, or max 1 tooth before.
