    I'm not using any sort of stock ECU so I wouldn't really be able to help you much. You can program out EWS though if you want, that's what I would do if I were using the stock ECU.

    Do you have any wiring schemes, to connect m52b28tu engine wiring - to e30 connector?

    I`m also installing m52b28tu @e30, but in my option it will be with EWS and all other things. Only when collect some extra founds will - flash out EWS and secondary lambda sensors + chip.

    I've got a guibo that will allow me to use the stock E30 shaft for now... That may not wind up being permanent once I go forced induction...


    Everything is on the back burner right now, I've barely got any income currently and I'm waiting to hear on a job I interviewed for in Austin. If I relocate it will be on the back burner until I find a place with a garage and get on my feet in Austin.

    I'm thinking of converting my Pathfinder to Megasquirt as well to see if I can bring out just a little better mileage. I'll probably keep that in mind for that project. I bought prewired DB37's for the M54 swap. Probably won't do that for the Pathfinder.

    I use crimped pins and connectors for my DB37s now. you can get individual solder pins too. I throw away the junk that comes with the MS kits.

    Yeah I was finding that as well, I had probably 1/2 of the wires already soldered on but I just didn't trust them to stay on there TBH. Some of the wires were already going to try to interfere with the case fitment. It wasn't super easy to get this to fit either though, I did have to drill out every single hole on the board that a pin went through, they were just a little bit too small. Glad I have a good bit set.

    Since my budget is so shot I decided to look at my Megasquirt breakout box. I wasn't happy with wiring directly to the terminals so I picked up a piece of predrilled circuit board and attached it to the stock M54's DME plug:



    I think this will be a lot more solid than how I was previously doing it. It's not pretty but it will work.

    325iX brake booster is in, swap can finally move forward!

    Still working on fitting my brake booster. I modified the fork hoping it'd give me enough room to just bolt it in, unfortunately it still wasn't enough so I'll need to thread more of the boosters' shaft and shorten it a little bit more.



    Just moved the hole back some and notched the inside of the fork just a little bit more so it'd accept the brake pedal lever. Used an X bit from my machinists bit set to drill it, was the exact diameter of the original hole.

    Just cut this out of some cutting board. Adapter plate/gasket for the E34 M50 throttlebody to mate it to the M54 manifold.


    edit:

    hoveringuy's engine bay shots answered my question about brake reservoir. Going to continue on with the E34 reservoir.

    Well, started installing the brake booster today since I have the master cylinder now... Realized I'll need to shorten and thread the shaft so I have enough adjustability for the pedal...

    I'm still not sure why exactly I'm supposed to use a remote reservoir, the only thing I can assume is it's because of the location of the E30's power steering reservoir but if that's the case then it's no issue because the M54's reservoir is a part of the engine assembly so I don't have to use the stock E30 location. The E34 reservoir also appears to clear the hood so I doubt that's the issue...
