Well here I go again. In keeping w/ my "backwards build" theme, I'm starting the build on the ECU for the future Fairmont.
Unlike my last project, which was an exercise in how primitive I could build a car, this car will be the opposite of that. Where as last years car was carbureted, this one will have digital, laptop programmable, F.I.. Where in the last car was naturally aspirated, this car will be force fed. Given the the engine is exactly half the size of last years car, it will almost have twice the power. To accomplish that, it's gonna have to be forced to breath the air at about 2 times the atmospheric pressure we breathe.....aka AROUND 30 psi of boost. It will be fueled on E85 and will not be intercooled so...........
To insure I don't blow up junk, I chose a complete stand alone kit, as I intend to replace the entire engine harness on this car. I will replace the entire electrical system for that matter.
You do not have to do it that way however, Megasquirt makes kits that will directly replace the EEC IV so that you can retain your engine harness, but I'm all about hiding that crap, so I'll start w/ a new custom harness to that end.
I chose the MSII kit w/ the 3.0 motherboard. I will let me provide for controll of fuel, spark, distributor less ignition, boost control, and it features an internal 4 bar map sensor (optional).
There is a even better step up MB, (v3.57) but for my purpose had some extra stuff that I didn't need.
Introductions aside,...it seems I have forgot that I have to get ready for dinner, so I'm gonna have to continue this the next time I sit down...pics to follow.
