    Modify RV8 3,9 Ltr

    Hello,

    In my Pilgrim I am driving the RV8 3,9Ltr. fired by two Stromberg carbs.
    Due to Gernan car tax, based on emission and EURO level, I have to pay an immersive tax until the car reaches the age of 30 years (official historic car). Mine is build in 1991.
    So I am thinking about modifying it to a fuel injection system.
    Anybody already made this?
    What do I need beside the fuel injection system itself? I think about:
    - wiring
    - ECU?
    - Lamda Sensors?
    - flywheel sensor?

    Thanks to everybody who can help me a little bit.

    Regards
    Markus

    The earlier EFI systems can be run without Cats, using the correct tune resistor.

    As above, plus fuel pressure regulator and a return fuel line back to the tank.

    Markus,

    Merry Christmas.

    If you are planning to use the Lucas 14CUX system (as fitted to the 3.9 engine in the Range Rover Classic) then you will not need a flywheel sensor as the ignition uses the standard distributor.

    In addition to the ECU you will need all the sensors, the AFM and the wiring loom. You would also need the plenum and inlet manifold from the EFI engine.

    I attach a guide to the EFI operation which you may find useful.

    Hope this helps - good luck!


    Regards,
    Ian

    Injection for RV8

    Hello together,
    thanks for your Information.
    Especially to Ian. The Manual might be a great help and it doesn't look too difficult.
    Tank with 2 connections and line back to the tank is already installed.
    Fuel pressure Regulator is also installed.
    If cats are really necessary I could go for so called mini-cats.
    Biggest problem might become the flywheel sensor, since the engine is already in the chassis and any mechanical modification might be difficult.
    The injection system is named HRC1579. Sadly it doesn't work with me attaching any pics or documents.
    I have no iedea if it is a LUCAS 14 CUX or any different one.
    So hoping this is the right one, where can I get wiring loom and AFM (sorry what is that?). Germans do hard with the typical abbreviations. Sorry for that.

    Thank you for any information regarding the missing parts

    Regards
    Markus

    AFM Air Flow Meter.
    You should probably Jim at RV8.

    Simplest way is to buy an efi system off eBay http://www.ebay.co.uk/itm/122287942670 add a megasquirt ecu using your dizzy as a trigger from www.extraefi.co.uk, add a high pressure fuel pump and you're good to go! You can add lambda sensor if required, wiring is simple too!
    If you already have the efi system, then just the ecu and wiring required. No cats, lambda is useful but not essential. It can be triggered off your distributor our try a front crank pulley trigger wheel from www.trigger-wheels.co.uk

    of course.
    I think Tony is correct in his suggestions, unless you already have the RV8 EFI bits.

    I'd say the simplest way would be to buy a complete Lucas EFI system from a Rover engined vehicle.including the loom, injectors, sensors, manifold, plenum, air flow meter(AFM), relays and ECU. The fuel rail should have a pressure regulator, although you can add an adjustable one.
    I say this is the simplest route as everything is made to fit and so you don't need to make anything up.
    You will need a high pressure fuel pump and filter and, ideally, a swirl pot to maintain fuel supply during cornering.
    The Lucas system uses resistors to select a tune (5 available) at least one of these is a none lambda type, hence no sensors or cats needed, if the system you get uses a different resistor it is no problem, simply change the resistor to select the required tune.

    Alternatively you can use a Megasquirt or similar but will require you to make up trigger wheel & crank position sensor (CPS) and loom, on the plus side you can also use this to drive the ignition and can get rid of the AFM.
