So this was the deal, I had a obd2 harness from a 1999 donor car, all e36 engine harnesses made after 11/98 are considered a late model style harness. it seems that bmw changed the style of the crank position sensor after November of 1998 harnesses made after those years were updated with a newer style crank position harness connector. Since I am running a s50 which originally is an obd1 motor I had to use a special crank position sensor that was used on the European model E 36. The connector for that sensor is square and the same as earlier model obd2 harnesses. After sourcing another harness that I can use, work resumed as usual. You may be asking yourself why didn't I just switch the connector from one harness to the other or just make my own connector? If it was as easy as splicing a couple of wires together I would have just done that, the thing is when BMW updated the new sensor they also changed the power requirements to that sensor and how it talks to the ECU and the operating voltage for the crank position, it uses 12-volt signal now, so they had to create an adapter harness for the older model e36s in order to make that new sensor work. I was also able to service my 3.23 lsd that I got for the build. I ordered all condor mounts and bushings for the car and was able to pressed in the diff bushing. Now some pictures That's crank trigger sensor I'm using m50 intake manifold with vac port installed diff serviced cleaned and new bushing pressed in my power steering lines and cooler to replace stock bits picked up a used dipstick obd2 finally got a mtech bumper to use, needs to be painted also have this on the way I had the stage 2 in my e30 and thought it wasn't aggressive enough for my driving so gonna try stage 3 Sent from my SM-T817T using Tapatalk Last edited by Deeznutz; 11-18-2015 at 05:27 AM. | | | 11-18-2015, 05:26 AM | #10 | Member Join Date: Jun 2015 Location: Brooklyn Posts: 58 | A customer came buy the shop who just finished his s52 swapped Ti seeing this was motivation for me to get this done soon!

Will it be legal? Sent from my SM-N900V using Tapatalk | The difference between obd1 and obd2 is all sensors and software just about any motor can run obd2 if you have the right parts. As far as it being legal, it actually is because I'm bringing the motor up to the same emission standard as the car. Since car is 97 and obd2 it would be illegal to run s50 obd1. But at end of day who is checking these things I don't have inspections to pass. | | | 11-25-2015, 02:32 PM | #15 | Member Join Date: Jun 2015 Location: Brooklyn Posts: 58 | Last edited by Deeznutz; 11-25-2015 at 02:37 PM. | | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Thread Tools | | Display Modes | Linear Mode | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
