  • AEM EMS install s13

    I have an ems 4 from my miata that I want to install into my car. This may end up beeing a full install thread. I have a1990 s13 with a s14 sr20det in it.

    This is the computer that I am planning to install.

    Is there anyone out there that have done this before?

    How do I get a screen shot to post?

    Any help on the wiring would be great. Any help would be great as well.

    Have a great day,
    Jared

    Why both the ems-4 and the FIC?

    Id use the universal harness. That's what I plan to do.

        Use the 1601 instructions for a pinout. theres also another one thats pretty helpful somewhere on the net.

        should be pretty easy imo

          Hello, I am in the process of wiring in a Link G4 Storm universal ECU into my S13 with redtop SR20det.
          http://www.linkecu.com/products/engi...-ecus/g4-storm

          I did not want to butcher the engine harness, so I got one of these:
          http://www.diyautotune.com/catalog/d...pin-p-426.html
          I'm not sure if the S14 SR uses the same ecu connector, but I believe you can get something similar for it.

          Will have to run a couple of external wires for IAT and WBO2, but it's an almost "plug n play" setup. I did this as the car is a daily; I work on it during the weekends, and it helps that I can plug the stock ecu back in to drive it for work. Hope this helps

            I am planning on using the jumper harness and doing the same thing for the install.

              At that point I'd just get an EMS series 2 if you're not going to build a new harness.

                The thing is I already have the ems 4, 3.5 bar map sensor and IAT. All I need is the disk and patch harness. Also I was goiing to buy a harness even if I bought a pnp unit. Also I am not going to go crazy with it any how. So I am looking at about $150 or so as aposed to $1000. There is a big difference in price. I dont want to butcher the brand new wire harness that I just bought and I like the fact that I can swap things out if need be.

                Thank you for the insite though.

                Have a great day,

                  if you are looking for a professional patch harness and don't want to do the work yourself you can contact mitch at MP tuning, that is what he does, and he is always spot on.

                  otherwise it should be easy enough to sort out if you are willing to do it yourself.

                    Thank you. I completely forgot about him. He has come to the shop I work at and has tuned many cars.

                      Someone should do a jumper harness group buy on here... I want one for my S13 KA-t setup.

                          So I am going to thry this out with the original harness that came out of the car when I bought it. The car ran fine I just didnt like the fact that it was all hacked up and wanted a cleaner look. I can either cut the factory plug off or get a jumper harness. This is for ****s an giggles and if it works maybe for sale.

                          So here is what I have so far. Any help is apreciated. Listed as follows EMS pin/functionffactory harness pin.

                          What wires do I need to run for the dash?
                          Anything else that I am missing? There is 3 GPIO that are unused.
