    From what I've heard, there's an optimal point for each car. Depends on your engine. You can advance it fully on CNG.

    Expert opinion sought.

    get your tappets checked ... tell your mechanic to adjust them to 10/10 when the engine is hot. keep your timing on 10degrees. make sure he tunes the car on petrol first and then adjusts accordingly on CNG. keep the RPM at 900 +-100 on both petrol and CNG ... close half of the the intake area to increase pick. this will give you better consumption as well as good pick. i've done this on my cuore and works well. going up mountains on cng is no longer a problem.

    good luck.

    As far as i know, Cuore ECO has got a timing adjustment mechanism in it. Timing is set as advanced by default to work witH CNG and on petrol that device adjusts it as per requirement of petrol.
    Degree of advance is usually judgement call for mechanics
    Keep a cool head and wear seatbelts!

    Go for as musch advance as u like, but be careful about the knocking/pinging; if u hear it retire the distributor a bit. If rough a bit rough idle is not a problem then u can use a bit more advance with slightly rough idle.

    Cure uses vacume force of the manifold to maintain the advance curve. Once the initial timing is decided rest should be left for the vacume diaphram to handle.
