Need serious help with wiring my MS2 here :/
So I recently bought myself a PNP MS2, or so I thought atleast. What came in the mail was a small box and a couple of connectors and with that a usb stick with the wiring diagram.
I have no clue what to do here but I have a faint idea but what I'm really struggling with is separating all the connections. like for example on this car (ref picture with wires) the 1&3 injector and 2&4 injector is one pin each, on the MS2 they want one connection per injector, how do I do this? As for the words on the sheet I have a faint clue but as I noticed they ask for Crank input + and -. As far as I can see the crank sensor is 2E but how do I get a plus and minus for both crank and cam. The same goes for a lot of things here so some pointers would be really nice. Gotta learn this stuff and I'm really struggling with the sheet I was handed from the dealer. By looking at the pinout sheet I can se IAC (Idle air control valve) thats one pin, and when looking at the sheet from the dealer they want IAC1A - IAC1B and IAC2B - IAC2A. http://www.miata.net/garage/ECU%20Pi...90-93%20MT.pdf http://img.photobucket.com/albums/v6...uts-1hidif.jpg The documents I've been working with. http://puu.sh/rpKcK/b2fab8d881.png And this is the wiring sheet for the MS2 from the dealer. It's a 92' 1.6l 115hp ;) I'm very gratefull for all the help! :) |
Exactly what MS2 do you have? That wiring sheet does not match any MS2 pinout I have ever seen. Can you post a picture of the ECU, and where you got it from?

This is the document and "wiring" diagram I got with the MS2 boks.

Can you post a picture of what is inside the box and details of where you got that thing?

I'll look into it, got it from SH-tuning in Norway, a well known tuner here in the community that makes them :)

So why are you not going to them for help if you purchased it from them?
I've been talking to the lads back at SH tuning and gotten some progress into this. I've talked quite a bit with the guys over there and they are just a reseller of the module, its biased off an MS2 with an "improved" pin table with indivudial injector and spark. Whether thats true or not I have no clue. But back to the question. what exactly is needed for me to run this system, the tuner said that I wasn't to worry about f.eks TPS because I could use the MS2 to control that instead. |
The problem is that we have no clue what is "improved" or how it is built, or anything like that. I have never heard of this MS builder and I'm doubtful anyone else in the US has. So you are really at the mercy of the people you bought it from.

If you can post a picture of what's inside, this will help establish whether the unit is, in fact, a MegaSquirt. I don't think it is.
