E36 obd1 obd2 conversion
 
I have a 93 325is with a s50 block and m50 head i need a obd2 conversion for my wiring harness does anyone have any information on obd1 to obd2 swap sensors,computers diagrams etc. please help

what?? iirc the part numbers for the heads are the same....

and i thought s50 *was* obd1....why do you need to go obd2 on a 93??


i'd get the right tune for the s50 and then should be just plug-n-play, no??:dunno:

there's a thread about 'how bmw's are like legos'. think it's in one of the stickies...

but i am sure more will chime in on this subject....

Also curious as to why you need to go obd2. Generally making an m/s52 obd1 to use in an obd1 car is common and its a painful process for a first timer. But going the other direction, why??

I don't know why you'd ever want to waste your time refitting a car from OBD1 to OBD2.

OP, your car was OBD1 from the factory, and has an OBD1 engine installed. Why do you want to switch to OBD2?

Hence OBD2? How? If it's hacked up, just replace the hacked up OBD1 parts with OBD1 parts that are not hacked up. Much easier.

All cars sold in the US from 1996 onward are OBD2. Anything before that year (including your '95) is OBD1.

Thanks mate !!

for clarity, anything designated a 96 model year (can have a x/95 production date....) is an obd2 compliant vehicle.

it should also state this on the emissions placard under the hood where the engine displacement and emissions information is posted.


and i agree with karl. if it was hacked, it's best to simply put it back together un-hacked and keep it obd1.
