OBD II In OBD I car

[applecrisp]

Okay so I have searched but I keep finding the opposite of what I am trying to figure out. Currently in my area there is a good deal on a m52 OBD II swap that I want however my Ti is obd I how hard is the conversion and if there is another thread on this topic wanna... direct me thanks guys

[pdxmotorhead]

The common deal would be to do a OBD1 conversion on the OBD2 motor.

But I keep seeing that as long as you have the full engine harness, ecu and cluster your fine....

Watching this with interest.

I don't know a lot about M52's but if it has Vanos I would think you are going to have a issue unless you swap the complete OBD-II DME and wiring into your car. Some sensors will be different without the OBD swap too

Maybe someone with more knowledge can help you.

I remember someone on this site saying that they did the swap without even converting it, they just kept the engine OBDII without having the OBD plug under the dash, sounds like the simplest solution, you can still get the codes through the round diagnostic port under the hood

One story I heard, was the OBDI intake manifold makes better power, but wont work with the OBD2 programming?

Truth?

False no programing needed you will get more power from the OBD1 mani ur going to need a bracket if ur keeping the OBD2 fuel rail.

Hows the tuning support for OBD1 vs 2? Either one easier? Harder? not worth messing with?

I would not think it would be that hard to install teh OBD2 connector unless its tied to teh cluster. I think I saw in a wiring diagram that its tied right off the BMW plug. Just uses the CAN bus or whatever and does not access SRS as well?

Tuning for OBD1 and OBD2 is a battle for either way people will fight about this all day. I like OBD1 set up chip swapping is must easier, no dme info swapping with a code reader I.e shark injector etc. Also as your car is OBD1 that's the easiest way for you to go.

Its not a difficult job to convert the OBDII engine to OBDI properly, hell, there are kits for it and it makes power from the tune, not just standalone manifold swap. The ports for the OBDII manifold are smaller and shaped differently for torque whereas the OBDI is straight and helps with top end breathing, which is where you get your numbers, not a significant increase until in upper rpm4500+ range, where most dont spend their time.

Thanks, Blue, I've got a 95 M3 engine in my car, and your note explains why it really comes to life going thru 4500. :-)

Sorry but i'm a newbie, and i know this thread is about a year old....but i am having problems with my car not starting. I don't know if it is OBD 1 or OBD 2 but since its a '96 (318ti m3) I willl have to assume its obd 2...i took it to the mechanic and he said it was the DME that was bad....I REALLY do not want to cough up 1300$ for that New DME..i was thinking of putting one of those 413 Red Label DMEs In and bypassing the EWS but i hear its not that easy for 96 and after.....is there any way you can explain to me how to convert it to OBD1 ?

I charge $100 to remove EWS from M52 or S52 OBD2 computer

DME must be shipped to me for flash
