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

I went back to the ref today… and left with a sticker! Notes from the second time around:
- I was failing before for very high HC and slightly over max NOX.
- Since the last time, I replaced the cats with new Walker CalCats, cleaned the MAF, and replaced the plugs.
- 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.

Would you mind posting the chassis and motor details of your swap?
Thank you!

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!

What airbox are you OBDII guys running to pass BAR? The Z3 one I have doesn't seem to fit at all and I really don't want to move the ABS module. I know there's CARB certified airboxes for e36 that may work, but since I'm BARing mine as a Z3, I don't believe I can use them.91 318iS - aluminum M52B28 + ZF320 + 3.15 Torsen

I have a Z3M motor in my 87, I am close to passing and have had this CAI already approved by the ref. Comes with a sticker and heat shield you need to customize.

I used a KnN e36 conical filter attached directly to the AFM from the s52. Gotta have the CARB sticker or you will not pass. I printed the exact reference description for the applicable CARB number as well so the ref didn't have to go looking (and potentially get wrong info). Once he verified the sticker number applied to the year of engine, he didn't really say anything else about it. Sent from my SM-G960U using Tapatalk

Thanks for the info from all previous posters.
I found myself wondering what different engines failure limits were, ended up finding the page here. Might be helpful in knowing before testing. https://www.bar.ca.gov/pubwebquery/c....aspx?make=BMW
ASM 5015 is the 15 mph test, ASM 2525 is the 25 mph test. I matched these to previous posts to verify they are correct, so thanks to those that posted their FAIL/PASS slips!
I'll be trying to pass an OBD2 S52, with all emissions equip...

Hey guys,
First post here. I've been doing research trying to find answers around the exhaust. I'm in the process of doing a OBD1 S50 swap and got all original engine, ecu, headers and midpipe from the person who sold me the engine.
My question is, can the midpipe be modified at all if I reuse the 2 stock cats? If not, then how are you guys fitting the midpipe. Mine hits both the sway bar and the lollipop.

If you want to make the unmodified midsection work, you'll have to use the offset "eyeball" arm control arm brackets and clearance the subframe as shown here.
