Why cant I run my M52 in OBD2 configuration on my swap?

You can use all the OBDII stuff. Here is a couple of pics of my engine bay:



Here is how you do it:

It is from e30.de. If you are not good on the german, there are page translators out there.

All you are gonna need is: (this stuff have to come from the same car as the engine; ie match with the ecu)
EWS-II ecu
Antenna
Signal-booster
Key

Then you need to make 5-10 connections (depending on how much you want to have working; ie Diagnose and more) which is pretty basic stuff.
The wiring is described detailed in the link. If you can't figure out the german stuff i can help with that...

... you are my hero. i've been looking around for a long time and most i've come up with is this:


where pins 1 & 3 of the EWS module are reversed so says the ETM for my s52 (which i am atempting to keep obdII) They are basically say the same, ex. i never really understood the whole ignition loop thing, but now i do. Thank you!

btw. the "Signal Booster" ~ Transmitter Module, doesnt need to be from the same car, neither does the ring antena. Key, EWS and ECU do need to be from the same car. just to clear things up.

didnt mean to revive thread, the search button sucks i came across this thread by mistake

what about something like turner's EWS delete chip for the ecu? but the ecu must be a EWS one IIRC for it to work w/ the OBD2 setup.

last i checked, there is no ews2 delete available for seimens dme's. This was from Turner motorsports. I think they did say it was available for Bosch stuff. You would have to confirm that.

Thanks for posting, Skyliner, and welcome to r3vlimited!

Sounds like i'm screwed. I dont have the ECU/antenna/signal booster/key from the original car, as this was a "mail order" motor.

Looks like I'll just have to pony up for the OBD1 stuff!

Wow thats a sick bay.

I did the same thing with the ICV.

That was purely personal opinion. Im the diy type and like the fact that i can tune it if i wanted to. I agree with you that the computer is better but untill an OBDII ecu can be tuned as easily and as cheaply as the OBDI i dont see OBDII catching on in the "tuner" crowd and for people with cars like ours.

Sorry i offended you.

OT: Hows that ICV?

I'm not offended... I just want to keep people's minds open to different ECUs.

Haven't used the ICV yet. Not sure if I really need to swap it.

OBD 2 sucks.

Wrong. Totally wrong.

The Siemens OBDII ECU is 10 times more powerful than the OBDI Bosch one.

Unfortunately, it's also harder for the DIY-er to program and adapt to work with a non-stock setup.

For now, OBDI is the way to go, but eventually it will be worth it to swap in an OBDII ECU.

[So Live]

Fair enough. Good luck bro. Document the shout of of what you have to do to make it work and then post it here!

[RyanZ06]

OBD 2 sucks. Why would you use it? Wouldnt you save alot of trouble by converting to obd1 than get the thing working on 2?

Because I'm not interested in modding the motor until I have my funds lined up to do the rest of what I have planned.. (OBD1 swap and turbo).

Thanks!

You can, and it's been done.
There are at least two cars I've seen on this forum that are running OBDII.

Do you know any of their user names here?? That would be most helpful! :D
