I have a possible solution that in theory should generate the required negative voltage to trigger the ignition box, it's just not yet been tested.

Mine being a 928 has an 8 Pin CDI - which I believe is basically the same internally as the 6pin 911 unit. The system triggers as the voltage goes below Zero so a RS232 serial driver chip may do the trick. I have a spare ignition box so if it all goes horribly wrong I don't blow my original good one

The test should be possible shortly after I get the beast running again with the new CIS-E fuel system over the weekend.

Alternatively a MSD ignition definitely works with the MicroSquirt and we also know the MicroSquirt is happy to take a direct feed from the VR sensor in the distributor.

Yes! mechanical/hydraulic constant flow injection can be managed by a modern EMS
