EDIS module fixed on the engine?

[GGR]

Hi all,

I read everywhere that the EDIS module is very strong and reliable. I therefore confidently made a bracket to hold both coils and the module where the dizzy was. The bracket is held in place by three rubber mounts to absorb the vibrations and is located right behind the fan propeller so that it will be in a constant air flow to keep temperature down. Here are some pictures:







I like that set-up because I can take it all out quickly and easily and replace it with the dizzy if something goes wrong, or with COP when I upgrade to MS3.

I'm nevertheless starting to have second thoughts: Am I not trying to push my chance too far by having the module located there, even if mounted on rubber blocks and in the fan's air flow? Will it take the abuse? I would hate to have to put it somewhere else now that I did the job. But better before than later in case you tell me that set up is bound to fail for sure! What do you people think?

Thanks!

I think it will be no problem at all. as long as the wiring harness is up to the job.
If you have spliced leqads onto a cut off connector by soldering and have those joints taped up close to
the module , the risk of failure will increase.
Why not disassemble the connector, take out the pins, remove the old wires and solder in new leads
with no exteral splices.
Will aso look much neater!
I have helped a friend on a 302 Ford , we put all on top of the engine under the air cleaner/manifold.
Never a problem for three years.

Thanks Heribert, that's good news!

I didn't know about the increased risk of failure due to joints close to the connector. Why is that?

[Heribert]

The reduced bending radius . One end of the joint is virtually fixed in the connctor while the other is routed away at an
angle , at least some of the wires are like that. So the bending and vibration stresses will be exerted over a rather
small distance, in the middle of which is a soldered, stiff piece of wire.
Breakage can occur just where the solder flow out into the strands have stopped.

And, with a beautiful MB V8, it looks a bit messy, too.

Ah, I understand now. In fact the pigtails are more than 10 cm each so I guess this is enough to avoid this problem. I need to look closer at it and I will go for the best option. I'm not sure I want to mess with older connectors though.

BTW, by some comments I read from you on other threads, you seem to know these MB engines quite well. This is an early euro 5.0 alloy block M117 out of a '78 r107 450 SLC 5.0. I have mated it with a manual transmission and I will fit it in a '62 W111 Coupe, currently equipped witha Djet 3.5. As I want to reuse most of the Djet stuff, I have swapped the Kjet intake manifold of the 5.0 with a Djet out of a 4.5 which was designed as an EFI manifold from the begining. I also made the engine look older by fitting two early 3.5 cam covers. My secret wish is to make a custom manifold out of a 6.3 one so that the engine looks like a 6.3. But manifolds seem to be quite a complicated thing, and I don't want to mess performance for now...
