EDIS became too problematic for this application. It's been removed entirely.
That means I'm going to have to run direct coil control from my Standalone ECU... Additionally, I'm going to have to take inputs from the Cam sensor to run the motor, which requires Printed Circuit Board modifications, and a lot more complicated wiring... I'm learning as I go here, so progress has been slow...
The good news? I got it to start at least.

The belt obviously needs to be tightened... And the oil feed for the turbo leaks. I've already ordered a replacement.
I'm fighting a problem a lot of people have bandaided in the past... I don't think it's really understood....
The Cam+Crank sensor is a optical pickup with two outputs. When the CAS is powered, and the optical sensor gets to a hole in the trigger wheel, it then supplies ground to the wiring pigtail.
The setup is supposed to use a 5v 470ohm pullup resistor to supply a baseline of current. When the CAS provides a ground, the ECU sees below 1v. When the CAS has an open connection, the 5v goes entirely to the ECU. By means of doing this, the ECU sees high-low digital signals that it can trigger the ignition and fuel from.
The downside? If voltage would rather pass to the CAS than through the CPU, you can assume the path through the CPU to ground is higher resistance than from the CPU through the CAS to ground....
My initial build did not have any extra resistors in line between the CAS and CPU. When injector bank A fired, there would be an artificial tach signal on the Crank sensor. When injector bank B fired, the CPU would freeze...
Adding a 1k resistor inbetween the CAS and the ECU was a bandaid for the situation....
To me, it sounds like the injector drivers are grounding themselves through the ECU input to the CAS.
I **Think** i can put a diode on the input and remedy the issue. I haven't had parts or time to test though.
