I have a 1985 Dodge Omni GLH, it made 290WHP couple years ago. I was experiencing electrical issue with my car and decided it isn't worth my time to troubleshoot the issues, since there is only two possibilities, computers or wiring, none is available new. Wanting to keep the car, aftermarket ECU is the only option and Megasquirt / Microsqurit sounded so good.
For simplicity sake I went with batch firing injectors and waste spark ignition system, so the compact\slightly cheaper Microsquirt would work fine for me. I will only need one crank sensor and a 36-1 wheel welded to my crank.
So, the my Microssquirt input/outputs are the following.
coolant temperature sensor
air temperature sensor
throttle position sensor
manifold absolute pressure sensor
a/c sense wire
two set of Ignition coil
two set of injectors
a/c cut off relay wire
fan relay wire
fuel pump relay wire
Megasquirt has more options I'm sure, but I don't need them, why pay for them?
I have around $1000 into parts easy, Microsquirt ecu, 8 ft harness, E85 sensor, 36-1 wheel, crank sensor, uninsulated butt crimps connectors, heat shrink, crimping tool, relays, fuel boxes, fuses, E85 quick connectors, QuadSpark Ignition Module, 420a coil, 420a plugs wires, misc wires, sensors connectors, injector resistors, welding 36-1 to my crank, sheet metal screws, tuner studio, and etc.
All needed wires labeled.
Made bracket for crank sensor, using metal from the shifter bracket on top of the transmission. Will have to reinforce the bracket after the crank is welded to 36-1 wheel.
