Back to the school room with you. The MS needs RPM input to properly time injection and spark. Thats cam and crank. **** your tach. It doesn’t matter. You could turn it off, cut the wires, and set it on fire. MS will still run. It’s been such a long time, but I’m fairly certain the jumper is to allow the coil signal from
the MS to properly drive the dash tach, back when megasquirts didn’t have tach outputs. So in your case, not needed.
Run a composite log and see if you’re missing crank or cam signal, then start diagnosing that. If there’s no RPM signal showing in tuner studios, it’s probably your crank sensor/wiring/etc.
