OBD2 S50 up and running!

[e30onBBSs]

Well, mine was running fine until I had to send it for a cracked lower timing case replacement. That's when the problem started as the idling was like shit. So I got itchy and found that the ccv hose was connected to the charcoal canister. When I unplugged it, it ran OK but then the idle will drop then go up again like running on high cams. That's the reason why I've been researching but found nothing on it. What I did was I took out the big hose from the ccv and plugged in a small filter yet still it goes on and off like running on high cams.

I have no idea if an s50 has a FPR but on my m20 I had the same fluctuating idle problem and it was because one end of the fpr wasn't connected.

And nice swap!! Amazing stuff.

I used an obd1 (two port) intake boot and ran it to one of those holes, and the ICV to the other. IAT is re-threaded and in the M50 manifold.

We ran full OBD2 CCV system with M50manifold.com adapter setup

Do you have photos of it by any chance? Mine doesn't run on a full adapter set up

Where do you connect the hose from the ccv if I may ask?I'm running on the same set up -S50 with obd 2 and a 52 HEAD.

Give me/US a shout we can help with a list

Very helpful! Is there a complete part list to doing this OBD1 to OBD2 conversion? I see the crank sensor number, anything super secret on any of the other sensors like knock etc. ? Planing to do this on my turbo m50.

I'll be in the office Dave...

Customer is bringing car off to paint! Very happy with it!

So, my question is very simple:

When will there be a good OBD II S50 tune? Running on an M52 tune doesn't *really* count.

My customers S50 is running on a specific 3L tune on the S52 ECU.

Mostly diagnostics. No 'guessing' when driveability issues crop up; the DME tells you what is out of spec and you replace it.

+ Better fine tuning, real LTFT's, smarter knock detection, etc.

so the advantage is better mpg, better torque?

what exactly is the advantage?

See the threads on this.

I'm lazy and just skimmed this cause I wanted to comment...

I've been thinking of putting the s50 from my e30 into my e36 but realized that the crank and block don't have the same pick-up and trigger as the OBD2. I see your trigger wheel is exactly the same as OBD1. Anything special to do there?

I do agree that the Siemens engine management is light years beyond early Bosch. It's just a little easier for some.

The Key is the Super Secret OBD2 Euro Crank Sensor :D
PN: 12 14 1 703 277

Its designed to run of the front crank pulley just like the OBD1 one (although its a completely different sensor) because as you mentioned, no hole in the block for the regular OBD2 one!
