Motronic M 1.5

[Gumby]

I'm in the process of figuring this all out. My plan is to retain the stock 2.4 EFI system and swap the 2.4 manifold for a cut down 3.0l with a larger throttle body. The engine arrived to me with the manifolds and all wires disconnected. I have the complete wiring harness and ECU. The engine is from an Opel Omega A. I am having a heck of a time finding the wiring diagram for this FI system. Are there any members here who have experience with the stock 2.4l injection system?







Diagrams or pictures would be great!

Hey Man
If it would help, I've got full documation of the L-jet system from an early Datsun.
I think, believe, and, from what I've heard, they're very close.

I'd be happy to take a look at the documentation! Any information is better than no information.

You're a better speller than me. :-)
It's at the shop in paper form it'll take a me a few days to scan and post.

One of our European members could get a copy from an Opel or Vauxhall dealer.

haha sorry I didn't even notice your misspelling. I'm not a cunning linguist :-). Thanks for your help! I also discovered through my searching that this particular EFI system was also available on some of the 5 series BMWs.

Do you know if there are repair manuals for the Omega A 2.4 in English?

This evening I will take a look in the manuals I have. There are several that cover the various types of Bosch FI. If I have anything I will send the name of the publication(s).

I think I have a spare ECM for that system as well. I will let you know.

. . . make it easy on yourself, why not just look at a BMW 3/5/6/7 series manual . . . in US they're all in English and Motronic is Motronic is Motronic!

A small word of caution though, all the cars you mention are at least 6-cylinder cars and Motronic is, I believe, sequential (per-cylinder timed) injection versus the gang-fired injection of Bosch FI systems prior to that.

Not a bad idea on the manual. The efi I have is for the engine I have so that should be fine. I think there will be minor differences between the BMWs efi (few extra wires) but the majority of it may be close enough for me to use the diagrams.

Volvos also used motronic systems similar to the 2.4 you have.

After researching this problem theres several things to work around.
Seems the Bosch group was changing pinouts on the pcms like we change underwear.
So after running into a dead end I called a friend.
He's got the info but will need to load an archived disc.
Cross your fingers..

I figured most of it out with the manifold in place. Some of the wires had labels however most didn't. There were only two I couldn't decisively determine where they went.

For anyone else who ends up searching for this information the Omega A only came with the Motronic 1.5 and Motronic M 1.5.4, so that should narrow your search into what other cars came with the same EFI.

Hi, you may have sorted this one out, but otherwise could this be what you were looking for?
