    Well, technically, I passed ... But even after supplying the title to the donor car and showing the inspector that the VINs all match, I still have to go get a letter from a BMW dealership stating that the ECU has not been altered.

    So close, but no BAR sticker!

    I was allowed to watch and even fielded questions the first time. The second time I was asked to sit outside the bay with the rollers but could still watch.

    At the smog ref right now. Is it normal for them to refuse to let you watch what they are doing? I mean, I sort of get it; don't want to give any secrets away [emoji38], but I can't even be in the vicinity of the car?

    - I still was close to the max on HC (78/93)
    - The referee was the same one who inspected the car previously. Since nothing changed, the visual inspection went a lot faster, but he did check.
    - I ran the car HARD before I showed up (multiple high RPM pulls), and he put it on the rollers pretty soon after my arrival. I think this was a contributing factor last time, since the car sat for 30+ minutes while they got set up. This time it was more like 20, and most of that time it was idling.
    - They install the sticker in a permanent location on the body. He originally went for the engine bay, but I preferred the passenger's door jamb, so he obliged.

    Next I need to get plates, but the hard part is done! Super relieved this process is over with.
    Congratulations raj! Great job!

    Sorry, wrong thread. this is M50/52, please disregard.

    Hi guys,


    So I am in the process of trying to make my M20B25 swapped early 318i BAR'd. Currently, it is running on Bosch 380 and naturally, it doesn't have a Check engine light.

    1.) Would swapping a 173 DME allow me to be able to read codes via the C101 connector and not just through the stomp test? In case it is required for smog.

    2.) How do I go about adding a check engine light? from research, it's installing a light and wiring the hot to a switched 12v and grounding it to the DME. Can I simply tap into the wire the connects to the DME? if so, which wire? is it the gray wire?

    Thanks in advance


    Sorry, wrong thread. this is M50/52, please disregard.

    Visit https://www.realoem.com/bmw/enUS/select?vin=LC89094 and punch in your vin for the right diagram.

    1- The TB has two inlets for coolant hoses, one coming from the head and the other from the metal pipe. Since I will remove the one attached at the head for the temp switch, is it ok to put a T on the other hose and feed both inlets to the TB?
    Yes, I put a T and it passed.

    2- Keep the Secondary air injection pump and SAP from the S52 all the way to the intake manifold (Pump, electronic switch and valve). Just the way it comes on the s52.
    Yes

    3- Where does the intake hose (suction hose per realoem) goes. Don't see any inlets in the intake manifold.
    ICV under intake IIRC, clean ICV prior to install.
    Trunk mounted evap.

    Good luck

    Went back in last week, results.

    - The evap sensor needs to be set to ready, currently it is not.
    solution, I shipped the ecu to Markert Motorworks today, he has been most gracious in helping me to get the ecu compliant.

    Something didn't take on the ecu, I still have to set the evap as well as the 02 sensor to ready. Communicating with MM to resolve.

    - A code 10 that appears to be an air conditioning fault code. I searched the BAR site and found nothing stated about having the air conditioning operational, only emissions.
    solution, I contacted the referee, his response is that if it is just an ac thing it should be fine. I have asked for help from Dave Markert on this, hoping he can delete the air conditioning which would eliminate the code 10 fault next time at the BAR. I have all of the ac stuff but would rather not go there now.

    The code 10 fault was resolved by MM on the ecu and I can confirm that it is not required to have the ac system operational to pass BAR.

    - high HC numbers
    solution, I'm hoping that by having the injectors cleaned that it will cure this issue.

    Before the next visit I'm installing new spark plugs, cleaning the air filter and changing the engine oil.

    I still have high HC on the 25 mph test, even higher than the last visit. It was suggested the culprit could be a small air leak, performing smoke test to check. Passed the 15 mph test.

    Any input appreciated.

    Something like that will be quite a chore!... Good luck

    I'm getting near the end of this swap and am down to the wiring. I have the entire harness out of a 99 m3 and will be keeping obd2 and all of the smog crap because : California. I want to shoehorn all the wiring into the e30 m3 cowl covering for neatness and I am wondering what wiring can be eliminated from the m3 harness in order to make this a little easier. Anyone got a list?

    Thanks,
    Sean

    On the 15 mph test I measured 84, with 54 being the max allowed. On the 25 mph test I measured 33 when 37 is the max.
    I have the oem cats that were pulled with motor on the 83 k mi z3m donor car.
    The fuel injector's were black around the spray nozzle when I pulled them to be cleaned. I have been getting crappy fuel mileage as well so I hope this will fix that as well as assist in the HC solution.
