    its Landirenzo EFI Kit with same model branded Advancer and Emulator. Dont forget to ask the guy to affix Lambda Sensor in it. Better go to Some Expert Fitter. Moreover if u have Vario than do ask the fitter to decrease the Air Inflow with 27 Number. Enjoy........

    Nooooooooooooo! Dont get CNG on the iDSI, youre negating the sole purpose of the technology! :p

    With the sequential efi kit there is no need reduce the air inflow.
    converting to Cng does not change the purpose of the technology. Because the actual purpose of the technology is to use less fuel n wouldnt it b better to consume cheap n less fuel n which is more enviournment friendly then the expensive fuel.

    @GLI
    Sir, in my humble knowledge; i-DSI is a high compression engine, so gas works so fine there. And also: lower octane fuel produces knocking in high compressions. Unfortunately our regular fuel is 90 octane where as CNG is 135.

    High compressions also leave unburnt fuel, that is burnt again in i-DSI, so any impurity in fuel will significantly effect it & also is a serious threat to the catalytic converter, as far as I know.
    Now, we know gas is afterall: pure, contrary to Petrol which comes even with official impurities: E-10.



    @hassan101
    Lambda system is good, it offers better acceleration but won't give promised milage. It will cost you a lot more, in addition.
    Air control will increase the acceleration (if properly set), but will reduce the overall speed with an increased milage.

    Addition of performance plugs is good, especially on CNG.

    uiv,

    IDSI 1300 CC engine is rated at Compression ratio 8.8:1
    Steermatic1.5L VTEC engine is rated at 10.1:1

    dont know if you're confusing the VTEC engine with the IDSI one.

    The IDSI engine itself is not that powerful on petrol, i wonder how the car will perform on CNG ( i own a city IDSI M/T myself). Being an economical car, it need not be infected by the deadly CNG virus.

    yaar i have not personally checked the stock cars static compression ratio but as far as the priciple of lean burn engines r concern, they defenitly need high compression to make a powerful enough flame to run the car.

    though i dont drive a CNG vehicle but I would defenitly love to test the sequential efi kit on my 4throttle 4AGE 16V. As the Converters claim 1kg CNG=2ltr of petrol.

    @Akbargr8
    I'm sorry bro, but that's a wrong information provided by Pak Honda.
    i-DSI is 10.8:1

    the work of duel-ignition is at higher compressions. At 8.8:1 it's simply IMPOSSIBLE & worthless.

    What does your car manual say, anyway? Doesn't matter, the compression is 10.8 for sure.

    i-DSI is not powerful because it's L12A @ 76hp



    Peace out

    the ratio between the combined volume of a cylinder and a combustion chamber when the piston is at the bottom of its stroke, and the volume when the piston is at the top of its stroke. The higher the compression ratio, the more mechanical energy an engine can squeeze from its air-fuel mixture. Higher compression ratios, however, also make detonation more likely.
