So I was studying my old ranger EVTM's while creating a 2.9 to 3.0 swap computer pinout chart and noticed that the 92 3.0 computer has an individual output for each fuel injector, while the 2.9, EEC-IV 2.3 and EEC-IV 4.0 are bank firing with 3 injectors on each bank.
I know the EEC-IV 3.0 doesn't have a camshaft position sensor so I'm not sure how the computer would know when to fire each injector.
Another difference I noticed is that on all 2.3s, 2.9s and the 90 4.0, pin #4 is the IDM (ignition diagnostic monitor) I am used to seeing. On all 3.0s and the 92 4.0, pin #4 is called "Engine RPM Sensor Input". Is this the same thing as IDM?
Another difference I noticed is that on all 2.3s, the 90 2.9, the 90 4.0, and the 92 3.0, Pin 56 is called "Ingition Module RPM input" while on the 92 2.9 and 92 4.0, it is called PIP (profile ignition pickup) that I am used to seeing. I'm pretty sure these are the same thing. I'm going to look up what how they compare to the 88 2.3 turbo and how the TFI 2.9 and 3.0 distributor connectors compare to each other.
Also it's amazing how different the 3.0 computer pinout is from all the other ranger engines. They really shuffled a lot of stuff around compared to the 2.3, 2.9 and 4.0 which are all about 5 wires different from each other.
