PT4 used for hi-speed flywheel teeth
"crank" tach-in used for single flywheel pin
"cam" tach-in used for hall cam
I can probably test that way because I have Jean's board with the two VR conditioners on it. But as I'm sure you know, for this to work with minimal added circuitry, the two MS VR conditioners (on the V3 board and on the MS3X) would have to be used for the flywheel signals.

JS10 would be good for me since my MS is currently set up that way, but I can switch it if necessary.

Great! FWIW, factory redline on the Audi 20-valve engines is 7200.
