So I've decided that in the meantime instead of spending 1500$+ on a full standalone, I'll keep with my SAFC 2 that came with my car (made this decision after spending 1/4 tank just driving home 20 miles...), the only problem is that I have no clue where the hell I'm supposed to plug in the controller? I'm 95% sure when I initially bought the car, the previous owner showed me it (before I even knew what it was) and it turned on, but either he unplugged it when I said I probably wasn't going to use it or my memory is astonishingly bad and I unplugged it myself when I removed the unit the day after I bought it. Regardless, I've spent like 45 minutes under the passenger dashboard in the ECU area and can't seem to locate the connector to the controller at all. I've read the basic universal wiring diagram but I can't seem to wrap my head around it because it doesn't seem to translate easily into what Im seeing under the dash. Here are some of the photos I managed to take.
(excuse the metal covering plate partially on, I lost my 10mm after the first bolt)
If anyone sees anything that I don't it'd be a tremendous help because my knees hurt from sitting on concrete so long. If it's needed, I can take more pictures of other areas when I get home with the plate fully off as I just bought another 10mm. Cheers!
Th absolute cheapest I can get to standalone is buying a used PowerFC with the banzai harness and datalogit for 900$, which isn't "relatively cheap" in my standards anyway. I'd like to go down this path, but I don't know I'd get a plug and play solution for less money than 900$.
Engine management is something you don't want to cheap out on with these fragile engines. Buy once, cry once. Drive it stock until you save up enough to get something legit. Search the classifieds and FB. YOu can find some used Haltech elite stuff for around a thousand bucks these days. Blow you engine up messing around with crap you're going to end up spending a lot more or you wont have a car at all. Take advice from someone who's done everythign the wrong way already and learned their lesson.
Safc’s work. Not the greatest, but they work. I don’t like to use them to make large fuel trims for reasons everyone’s tired of me stating. Check your afr’s, find a way to check for knock.
safc wiring is pretty straight forward. It literally taps in and/or intercepts the wires to/from the ecu. Where the previous owner did that is your question, but you could splice in near the ecu plugs.
