    Running LPG and Dual Fuel.

    There are many threads dealing with problems from running Dual Fuel.

    I will try and deal with some commonly asked questions.

    Tuning for LPG

    I asked Alitis007 ( a very knowledgeable forum member) for timing, spark plug gaps specifications for a dual fuel RB30. This is his answer:

    "Timing is a bit fiddly because you need to find the happy medium between both fuels. Reason being that lpg has a higher octane rating than petrol so you need to advance (timing) slowly and drive the car and make sure it doesn't ping on either fuel.

    Don't alter the factory plug gap because that could cause a miss fire, you could put in a colder plug as lpg burns hotter, but if your motor burns oil using a cold plug is not ideal.

    The heat range of a plug is written in its part number, higher the number colder the heat range, as is other information like size, length, type and some other information irrelevant for now.

    As a example a BPR6E is colder than a BPR5E. Changing the heat range more than one number is not ideal either because you can severely alter the exhaust gas emissions of the car and possibly cause engine damage or premature failure.

    Without tools like a gas analyser that's all the information I can help you with."
    My advice is: not to follow my advice.
