    So, not a whole lot to report recently...

    DME and EWS are here, but I haven't even had time to install them. My shop was closed to customer work for September to give me plenty of time to work and fully focus on this swap, but last week I had a customer bring his car back due to suspected issues from a clutch install I did just prior to starting the swap. It ended up not being a clutch issue (thankfully) but it did slow me down quite a lot having to spend time diagnosing it and replacing other parts that were faulty...

    Trying to get back on top of things now though I also got in my little auxiliary 4 fuse box - though annoyingly my tool from FCP just shipped out yesterday, which I need in order to finalize the adapter harness

    Have also spent a good amount of time recently double checking all my wiring and comparing to the way it's routed from the factory and etc... it seems to all be correct but at the same time, I am not an expert on this stuff but I am trying to be extra careful in ensuring all my routing "makes sense" to begin with and also matches what the N62 DME/IVM will be expecting to see

    A fair bit nervous to be perfectly honest - if everything is wired correctly as far as I see it, but it doesn't start, then I don't have anywhere to turn to or anyone to ask for help really, as this swap is undocumented and N62 knowledge is so sparse...
    But, I am going to shove that concern back deep into the recesses of my mind and get back to working on the swap over the weekend to get hopefully everything prepared minus what I need that tool from FCP for... then when that tool arrives I think I can finish it all up and go for my first attempted start

    Of course, if it does work... it'll be a freaking party and I'll be super eager to get the rest of the stuff all done. Haven't paid for any fabrication yet either at this point. With the impending cost of this fab work, I am giving a lot of thought to just buying a welder and trying to pick it up myself. I'll think about it more and make a decision once I am at that stage. Obviously still a successful start away from really giving that any deep consideration

    Ends up that auxillary fusebox I bought fits in the Z3 DME box with no modification



    Re-did the fusebox and adapter harness as well... the fans will be on their own setup (although I need another switched power source for one of the fans now, so I will have to see where to source that)



    Much neater than the previous version The main reason I wanted to redo the fusebox portion is that when I was drawing out the wiring diagrams I decided to change where it got the constant power supply from and this new design reflects that change. Also, I wasn't really planning on doing this before a first test start, but when I noticed it fit the DME box I was like ooh thats cool

    I ended up having to order more pins as well, some of the same ones I already had but with a larger base to accept a thicker wire. I also found the other pins for the IVM power terminals I needed - so I can now run complete wires with crimped ends without any splices anywhere

    Next major step will be getting everything wired up and the DME installed then see if I can communicate with the DME via INPA. That is why the fusebox wires have no harness plugs for now - until the tool gets here I need to leave the terminals loose so I can plug them into their various spots. The pins I just ordered are for the starter supply - so I won't be able to start it until those get here, but I should be able to communicate with the DME in the meantime. Really hoping to get everything done for that tomorrow and potentially plug it in and give it a shot

    I also need to wire in the pedal wires! I keep forgetting about those pesky things...
    Trying to get back on track and continue to make some forward progress every day

    A small victory today, but a victory none the less... went ahead and mocked everything up now that the wiring is almost done (how many times have I said that? haha) - just waiting on a few pins for the starter circuit and then the electronic pedal wires to finish it all up.





    Had to install the whole engine harness, as there are some wires in the harness that run between DME and the IVM.



    And my small victory...



    You can communicate to a DME with very little actually working correctly, but it was very nice being able to connect to the N62 DME via the Z3 OBD2 port. The DME is tuned for my setup as well as virginized, which is something this particular DME needs done in order to be installed on a new chassis. Big thanks to my tuner I also installed the EWS and will align the DME and EWS tomorrow and hopefully get the engine installed as well, that way I will be ready for a test start as soon as those last pins get here...

    Tonight I will also look at the electronic pedal wiring and I plan on doing that tomorrow as well. I should have everything needed to finish the pedal wiring already on hand. I've just been debating between whether to use the Z3 M54/S54 style electronic pedal or install an E46 style pedal. I think in the end it will be much easier to go with the E46 pedal so that is what I will do for now. The Z3 pedal uses a different harness with different pins so I will cut the wires a little long in case I decide to convert to the Z3 style down the road

    So hopefully some good stuff happening soon!

    Anytime - though it'll be a lot more interesting to look at when it's closer to being finished

    Thanks

    Got the pedal wiring done today, at least all wired up on the DME side - just need to run it through the firewall and crimp on the pins once in place

    Very disappointed with FCP to be honest. With the depinning tool I also ordered 4 struts for my E39 wagon - 2 for the hatch glass, 2 for the hatch. The box was missing one of the hatch ones (which were pretty expensive!). The depinning tool did not have the protective "cage" clipped into the proper position, so it was not protecting the tip and the tip was bent on arrival! I bent it back straight and flipped the tip around so I could use it a bit in the meantime but super disappointing. I will e-mail them and see what they can do for me... was able to use it enough to move the couple pins I needed to use... and now the adapter harness bit is fully attached but still

    Come to think of it, at this point, all the wiring in the DME box area should be done! So at least that is a win...

    With that done I can now focus on getting the engine installed in place to go for a test start

    Good job and a good idea with virginizing the DME! It would have worked even with EWS3 or more likely EWS4.3, but you would have been unable to diagnose the EWS later, every transponder programming would have been quite problematic. This way you also keep the ability to order new keys from the dealership.

    I only have one question regarding this EWS thing. I suppose you have the newer EWS3D, do you? If so, then it should be possible to match DME to EWS. If not and you have the older EWS2, there will be a problem.

    EDIT: Oh, I see! The previous engine was M52TU. If the car came with this engine from the factory, then you definitely have EWS3D. Then you are safe. Diagnosable, programmable, everything fine.

    FCP will replace these for you no problem - guaranteed. I have nothing but good experiences with those guys, even when they screw up, they make it right.

    I still use FCP a lot, but I have had mixed results with their return program tbh. I haven't received any response from them yet... will try again today

    Got the starter wired up...



    And installed behind the exhaust, behind it's heat shield



    Engine re-installed. Transmission is bolted in at this point



    Engine wiring harness plugged in to DME, Valvetronic and IVM



    Succesful (and mostly meaningless) communication



    Not sure what the "status clutch: on" means here, as there is no clutch position switch wired in currently



    MAF is not plugged in, but it's at least reading the coolant temp and etc



    Valvetronic data



    EWS/DME alignment menu... will need to access this page for the attempted first start coming soon!



    Was happy to see some data from the camshaft sensors as well, even if the engine is not running, since I had to swap one of the camshaft sensors to the other style



    Today I am going to spend some time verifying all the wiring... triple checking all my work... and will be ready for a test start possibly Monday? I take Sundays off (gotta watch my AZ Cardinals disappoint me) and won't have time to get to it today. I'll pencil it in for early next week. I am trying to take my time but still move quickly

    I also received my gauge cluster today... nothing to see really... but if everything ends up working out, it will be sent back for a cool custom gauge face!
    I will install the gauge cluster later today as well

    Most important question of the entire build... What fabric combination are you going for with the interior?

    Thanks haha. Its only meaningful work if it actually starts though haha

    But no matter what happens, the real N62 swap is the friends we make along the way

    Depends on the exterior color but I have given it some thought...

    If it is British Racing Green, I will emulate the E36 M3 GT2 interior (https://cdn.bmwblog.com/wp-content/u...6-M3-GT-27.jpg)
    If I go Daytona Violet - I will have a custom M Texture made, with three shades of purple instead of the M Tricolor pattern

    Long way to go before I get there though!

    I'd vote for the green - it's awesome, and I've always like British Racing Green for exteriors.

    Hey, it's Sunday. You should be drinking beer and watching a game...

    It was a morning game - too early too drink. Luckily I didn't need to anyways as we actually won... (pretty meaningless win all things considered but hey)

    I went to the shop for just a little bit, documented the wiring on the car and came home and triple checked everything I wasn't 100% on. Everything seems good... have a few extraneous wires I will be removing (for SAP/DMTL which is currently disabled)
    I even "mocked up" the wiring changes on paper - printing out a page of the Z3 wiring, following my notes and making all indicated changes, then comparing the results to what the X5 DME is expecting to see. Everything checked out by doing it that way, did it twice just to make sure lol.

    Don't think there is any more avoiding it... I can only keep checking my wiring so many times before it's time to put it to a real test! Alright. Time to attempt a first start. Coming soon... tomorrow, possibly?

    Oh, also... found an M roadster locally for a good deal. May be able to work out a trade so I don't have to put any cash out for it either! It's a car I've been after for awhile (actually over a year) - but it recently got hit in a parking lot. Looks like very minor damage, I will buy it to fix up and enjoy while I finish the swap. Luckily I already have the parts on hand to fix it

    No start

    I may go back to diagnose later tonight after doing some research... I skipped lunch today so Im home now for an early dinner. My lovely girlfriend closes tonight so I have all night to do as I please. Which, you know, means researching this and more diagnosing later...

    Not a total loss as the EWS stuff did work which is great. That was confirmed working as I saw 12v at the starter output line. I was initially really disappointed but tbh, that alone is a pretty big win. So big thanks to Abel for that!!

    So quick rundown of what did happen as the starter did click at one point,
    Initially I went to crank, nothing
    Measured the EWS starter signal line - saw 12v when cranking
    This starter line is supposed to run through IVM - I bypassed the IVM and ran the wire with 12v when cranking directly to the starter, at this point the starter clicked
    Maybe low battery? Brought my jumpstarter over - the single click was much louder, but still a single click...

    Im gonna double check any silly stuff - install a better grounding cable, give power to the fusebox (IVM takes its switched power from the chassis, so maybe its not receiving power at one terminal and unpowering a circuit?) and spend some time now going over the wiring diagrams for the starter. I also have the starter line running into IVM as it "should" be for now (though I did make an adapter harness I can install inline so I could easily switch between the two)

    Also the lack of ews manipulation protection codes actually means the dme is talking correctly to ews and are paired fine.


    (FWIW a mismatched dme to ews would still spin the starter, but no ignition. Key to ews mismatch causes no actuation of starter)

    Well, I fixed part of it... Still no crank, but now the starter clicks with the starter signal line routed through IVM

    Getting closer but still no dice. Havent ruled out a faulty starter either

    One of the basic things to check as you were focused on the engine loom. Do you have a good and working engine ground?

    Yes that is good thinking. I had a short cable run to ground the engine and tried again with large gauge jumper cables to ground it while I was there earlier. Not sure the effectiveness of the jumper cables to ground it though. Im also wondering if I should try a larger size battery... Maybe even with a jumpstarter pack the smaller size for Z3 is not enough cranking amps for the N62

    Tomorrow I will run a better grounding cable and try again

    I also noticed awhile ago that trans has a grounding cable of its own. I will also ground that too (as starter bolts into trans, maybe this is more critical than I originally thought)

    I guess it should not be so much of a problem but it is a good start. As you said, you tested that the starter gets power from the IVM. Did you also measure the voltage there when in start position?

    I also have read about the previous process when you tried to run a separate wire to the starter. Did you try to put direct 12V on it to see if it will crank? As you tried the separate wire before, it is not very likely but IVMs tend to have cold solder issues on its own power supply connection inside. If you have a used IVM, this is what I would check, too.

    For a test, you can try to run the jumpstart wire directly from the starter body to the ground, too.

    Engine ground strap?

    Edit: Oops didn't see that it's grounded. But if the engine is grounded and you can't get it to crank with a direct positive jump to the starter: the starter is bad (or the solenoid).
