I've been working with my old v0.4 board on a simulator experimenting with different settings and checking the results on a digital signal analyzer. I've noticed something that probably isn't an issue in real life, but it would be nice if it could be fixed without too much trouble.
I'm using a 36-1 wheel on a wood router with a VR sensor going through a dual VR conditioner from JB Perf. The set up is for a 4cy, 4 stroke engine, waste spark, paired injectors, 2 squirts alternating. At slow crank speeds I'm getting chattering of the fuel pump relay until the period between teeth is less than about 34.645mS, which is about 48 RPM on a 36-1 tooth wheel. After that everything works beautifully.
A thread from a few years ago about hand cranking caught my attention. As I see it, if the engine is primed and you start the swing about 6 teeth before the missing tooth, you should be able to get the engine to fire on #1 and you're off to the races. If nothing else I think that would be a pretty cool thing to be able to demonstrate.
