FS: rebuilt Motronic ECU

[autokunst]

Hello all. I recently purchased this like-new rebuilt ECU from Bert for a friend, only to find out that my friend does not have Motronic ignition. EM6003, or 0059 ECU. I've attached photos of the unit as it has arrived to me from Bert. And here's a link to Bert's offering of it for reference. Consider me an accidental intermediary.

As I understand it, this unit was rebuilt, but never installed. It sat on a shelf for a number of years - like a NOS rebuilt unit.?.



Offering it for the same $165 shipped. I (my friend) will eat the shipping cost to you. Thank you!

Sorry Alan, not sure I follow. If you are interested, please send a PM. Thanks!

Going to bump this once, hoping someone here is interested. Else, I'll be listing it on eBay. Thanks!

Now that’s a cool abbreviation Alan!

Stephen,

I have a Motronic 1.0 (I think) with a 3.8+ liter engine. Will this ECU function well in my car? If it will, I'm interested and would use it in the car, and keep my current one as a back up.

Gary--

Hi Gary,
I am an accidental custodian of this ECU - I have carbs on my car. Unfortunately, I don't have a strong depth of understanding of what system(s) it will work well with. I am hoping an expert on the forum can contribute here. I can provide any additional information, numbers, etc that anyone needs from the unit or paperwork.

Not sure if this helps, but it looks like it was from and intended to be used in a 1986 635CSi (12/85 build date).

 

[autokunst]

Hi @Gary Knox , have you learned anything yet about whether this unit is a good fit for your car?

(yes, this public post is a thinly veiled attempt to get another, more knowledgeable forum member to chime in and say "yes, that would be a perfect fit".)

If I understand correctly, the S38b36 US M5 used Motronic 1.2. The Bosch 0059 is Motronic 1.0 with 28 pins used in the 85-87 e24 635CSi M30b34. Where is a Don when we need him?

I would try the www.mye28.com
forum. Many members there know this ECU very well.

I am sure I need @sfdon for a lot more than just this topic. But yes, his input would be greatly appreciated. @Gary Knox, per your comments above, it sounds like you have Motronic 1.0.?. I assume your 3.8 liter engine is bored (and stroked) out, rather than an S38 engine?

I've never been over there, but if this ECU doesn't work out for Gary, perhaps I can try to offer it there.

Yes Gary has an 12v straight six. It is more machine now than m30. Twisted and evil.

I just looked closely at the unit I have here. It has 35 pins. Not sure if that is different, but I get the impression that it is still considered a 28 pin device?

Also just found some additional information that seems to apply (almost too well):
M1.0 (adaptive), 28 pin - Bosch # 0261200059.
Originally fitted to E24 1985 - 1987.
Will also fit: E28 535i 1985 - 1987 and E23 735i 1984 - 1987.

 

[sfdon]

This should be a wonderful rebuilt ecu for a stock engine. Correct timing and fuel maps for a low compression, low smog, good gas mileage factory original 3.5 mid 1980’s engine.
Anything else - not good.
Stroked, bored, cammed, headers need not apply.
Why are they in demand? Because they famously crack their solder joints.

Well Gary, it sounds like this unit is not a good fit for your car. If you agree, I am going to list it on eBay.
Thanks all!

Stephen,

As you know I'm in the 'warmer west' (temps about 15 degrees below their historic averages for this and the past 2-3 weeks) for another 10 days or so. Thus, I can't check the number of pins on my ECU. Yes - engine is an e30 with 1.0 Motronic (as I understand) and had a new 3.5 block bored and stroked for about 275 hp with later (non octopus) fuel injection.

Since I can't really commit to it, and sfdon says it won't really function well with my system - gonna' have to pass.

Cheers, and thanks to ALL for their learned counsel.

Gary

Of course. Thank you for helping me learn more about this little box.
Mmmmmmm, 275 hp.

The return policy from our fellow members has been rather disappointing lately.
