    Good morning, has anyone any experience of marinising this diesel engine. I don't need any advice as regards the engineering side,just the electronics. I have a donor vehicle which runs well. The problem I have is knowing which parts of the wiring I need to retain ,connected to the ECU,in order for it to run as a stand alone engine . My Grandchildren and I would be most grateful for any advice.

    Best advice I can give is to purchase the big maint manual for that engine.

    May be 100L but worth it

    Ignition lock, immobilizer, throttle pedal sensor, low pressure fuel pump, inertia switch, lambda sensor and of course all the engine bay wiring and components. In fact you need everything connected to the ecu, which is quite a lot.

    You can often get really knowledgeable advice from boatdiesel.com
    costs 25 bucks per year US but can offer advice worth thousands

    Thanks for the replies, Fred I have long wished that our UK workshop manuals were of the same standard as some of the American ones I have seen ,unfortunately the two manuals legally available here are of very poor quality and content ,and yield very little of any use. CDK you are right of course but with 134 connections in the ECU how on earth do you know which ones to use and which to dismiss without damaging the computer ,because that is what it is ,also the instrument panel is CANbus which is a further complication. I remember you avoided all of this with your choice of VW conversion ,and with good reason, but the only way to get the power available from a modern engine is to embrace it.Happily some clever people have seen the need for a solution to this and after a long search on the internet I have found a company that will provide a skeleton plug and play loom for this engine ,using existing immobiliser and ecu. As these become more common ,and it is being driven by the kit car market ,it may open up some new possibilities for auto to marine conversions.Barry I think you are right it may be a good time to join boatdiesel.com

    When I had a problem with the ECU in my Vauxhall Frontera I bought Haynes TradeTechBook 3787. It describes all European gasoline fuel injection systems in use in that era; circuits, functions, peripherals and diagnostics with detailed information.
    I assume there is a similar publication for diesel engines.

    You might try a US online book source and pay for the duty.

    Boat diesel is a great resource but over 100 connections is a lot to need.
