I am by no means an expert on MegaSquirt, however I have quite a bit of experience on the 22re's, so hear me out. You have the distributor set so the rotor's trailing edge is past the tower. I know you're trying to set it up so the rotor lines up better with the tower terminal when you have advance ...

What about using a relay off the small starter wire or off the ignition switch? When cranking, the relay is powering one circuit, then when the key is released, power to the relay is cut causing it to close the other circuit. You would probably want to redirect the ignition circuit signals and not t...

I would suggest the MAP and IAC not use the same vacuum port though.
Wait for a few more opinions though- someone else may have a better idea.

Since you're hesitant to discuss technicals. If it uses mechanical valves, perhaps sensors there... say Hall effect sensors in parallel triggered by valve motion? Pressure sensing, piezo-electrically, intake pulses? Optical sensing on something external which moves at a fixed ratio with the cranksha...
