Ah, the eighties. A separate computer each for spark and fuel.

The weird dual coolant temp sensor is a neat artifact of that

The fuel computer gets RPM data from the EZK, correct?

Maybe Zach will have a chance to stick his oscilloscope on the
load signal between the computers. I bet that would be
interesting. I'm going to guess it's a 5v PWM square wave.
I have a Volvo with some half-done, homemade crap in it.
