Here is the plug.

I don't think our 6 button OBC's have the coding plug as our OBC's didnt have the extra features, so you need to procure one it sounds like?

"Matt makes note that the coding plug for the M10B10 may not be accurate because the coding plug was designed for the M10B10 as used in the E28 518i which had a 70l fuel tank as opposed to the 55l tank in the early E30 318i. There is also no plug for the M40 motor or any diesel motors. "

So if you have a EARLY 318i M10 coding plug, the numbers might be wrong.

"Not all the parts are necessary. The relay box, screws, lower wiring harness, alarm horn, and horn wiring harness are all needed if you want to use the code function on the OBC. The code function disables the car until you type a code into the OBC. I have this feature on my E36 M3 and I never use it and decided to skip the hassle necessary to install it."

"
I also don't believe the turn stalk is absolutely necessary. The OBC enabled turn stalks allow you to press the stalk toward the steering column and it cycles the OBC throughout all the OBC modes. I think it is worth the effort as replacing the stalk is not that difficult. "

Thanks E30tii. Exactly what I was looking for! Now I gotta pull the rest of the stuff off a jy parts car this Christmas.

If you get some extras I'll buy them from you!

After a VERY long wait (at least four weeks!), I finally have the coding plug. I now have everything needed for the swap, and will be installing it this weekend or next.

Jp, I grabbed two obcs, dunno if either work properly yet. I'll test both in the process of setting this thing up. I only pulled one of everything else though -- pretty much all I could find that was correct.

Cool, I actually pulled everything for the swap off an 89 325iS about a month ago. All I need is the coding plug. Where did you buy yours?

Bavarian Autosport. It was $65 iirc.

It has a manufactured 2004 stamp on it. I'm pretty sure they special ordered it from Germany based on how long it took them to get it to me.

It is installed, minus the code box and lower wiring harness. Seems to work fine.

Managed to break both tabs off the cluster though :mad: dammit. That would not have happened if I could have gotten the key cylinder out (so I could remove the upper steering column cover) but it didn't want to come. Oh well. Damn these airbag E30s. I'm sure I can fix it sometime.

so you put in the black box, the wiring, and the obc?

Yup. The signal stalk is optional. Get a new light bar and code plug while you're at it. The code plug will cost you $60ish regardless of where you get it from, BTW.

Wasn't bmwman91 going to make copies of this chip available for cheap? I realize it wouldn't be high on his priorities but would make some people happy.

Did anybody succeed to make copy of the chip?
Man from another forum gave me this:

That looks promising...I wonder if those are correction factors, and if they relate to memory blocks on the eeprom?

IvanB · « **Reply #26 on:** January 16, 2010, 04:11:35 AM »

The chip is ROM Its programmed once, and then you cannot reprogram it. Chip number is TBP18SA030EN. I did not find datasheet for it, but found for TBP18SA030N which i hope will work. As i read its 256bits memory, 32 words X 8bits. It has 16 pins. Now its up to someone reads m42 code plug and write it to another chip.

i have everything to swap but the coding plug also. i have it from an 87 325is. i already swapped the stalk when i put in the cruise control stalk so that is already taken care of

I just walked into a dealer and ordered one and will have it on Tuesday.

Oh yeah, I'm in Germany.

IvanB · « **Reply #29 on:** February 09, 2010, 07:10:41 PM »

How much did it cost you?
