That's great news Mike. There was too much at stake for Volvo or someone else not to find a solution. Some questions if I may!
Did you get a feel for when in the third quarter they expect to start supplying again?
Do you know whether the new ECU's will be different to the legacy ones (your post suggests they will be)?
What's the objective of sending ECU's for testing?
Why are they only interested in testing 72 and 73 series ECU's?
Thanks again.

Well done Mike
I think your actions alone have spurred some significant action.
There will always be a hundred questions that people will ask but that’s the nature of opening this can of worms.
I think you’ve done a great job.

Why don’t we just send the one off the boat in question.

They are coming to collect it from me on Wednesday morning Paul.
I have also been emailed by 2 owners who have 3 units between them so they (VP) will have a total of 4 to play with.

Hi Pete,
Two answer your questions in turn-Still awaiting an actual date in Q3 so I am guessing it could be anytime at this stage.
I was encouraged by the efforts that are being made and ever hopeful that it will be early Q3 ( am I setting myself up for a disappointment?).
I got the impression that it will be a replacement unit, not necessarily identical but that it will do the same things. Talks are ongoing with 3rd party manufacturers .
The objective of returning any units out there are that VP hope they can breathe life into one or more units and also ascertain why they fail. I also imagine that if they have also failed that perhaps there may be a common thread for causing the failures to "program" out of the replacements?
I am only asking for help on the 72 and 73 ECU's. I am simply doing my best for the owner of the boat concerned and any other owners who may soon face the same problems.
Thanks again for all the support an interest from everyone.
In the meeting I had it was commented that we have a lot of followers and visits to this thread, so VP are also following us.
Mike.

Makes sense to do a full forensic on them first .
Depending on the results ( common part fails ) they might be able to offer a small upgrade, retro fit Instead of the whole thing .
The upgrade being 2021 tech in terms of components.
This sounds better than just a direct copy by re starting the old production line .

I'm sure the Swedish dealers have access to a single and twin engined boat with the relevant engines.

Apart from the boost pressure sensor, it's extremely unlikely that any other part of the hardware could be replaced (due to the solid potting compound that the circuit board is set in). This is why none of the ECU repairers will touch them.
But, I have heard that re-programing them can work (my broken one is waiting to be re-programmed).
I agree. Hopefully, the new ones will be more resilient and will be potted in a softer compound so that they're repairable.
I live in hope that the new ones can be mounted off the engine (where they won't be subject to vibration) and be cheaper!

2 Engineers from VP met with me on Wednesday and undertook a very thorough check of the boats control systems.
As expected, the end result was that the unit was declared as "Fried".
There was no point in taking it away for further checking.
As things stand, we are waiting for either a prototype or a refurbished unit to be fitted to our boat for testing but I still have no idea if or when this will happen.
Roll on Q3 for delivery of a new one.

Was the engineers sent by volvo in respect of the ecu - if so at least volvo are seen on to the case and taking this problem more seriously.

well done for getting through to VP
will these new units only work for specific VP engines or are the new ones possibly smart enough to run e.g. a KAD 44 as well ?

At least it seems Kad44/300 can be converted to a purely mechanical injector without an ECU.....

From the last line in the webpage that you linked:
"The engine would now simply continue to run without any cables, because no one needs annoying electrics and control devices on a boat engine!"
Pity that I couldn't find a like button...
...Oh, and sorry Greta, but if a bit of smoke upon cold start drives you crazy, you'd better be prepared to face MUCH worse challenges in your life!

I don’t understand this post , the pics show a standard engine with edc control , nothing different there .
