    Default Sequential vs EFI Kit for Vitz AT 2003

    Hi,
    I have a 2003 AT Vitz and have been running it on petrol for about 5 years and I would say that the car is running smoothly and hasnt given me any major issues. However, now I feel that the its is very hard to manage my resources due to the high petrol prices which is giving me a lot of headache. Therefore, I have finally made the decision of shifting to CNG.

    I've been browsing the CNG section on PakWheels and was able to dig out some useful information from the threads given at the bottom but then again they raised some new ones as well. So here is what I've been able to gather so far.


    CNG for VITZ AT 2003

    Type of Kit:
    Closed
    Open
    Sequential

    Kits short listed:
    a) LANDIRENZO EFI CNG kit (as referred by Mr. Khalid from Maverik, Islamabad)
    b) LANDIRENZO sequential cng kit with lambda
    c) CNG SIS kit

    Advancer:
    a) STAP-3000
    b) tomasato one(if there is one)

    Threads used for Referenced
    CNG SIS kit on SWIFT or Vitz?

    Which CNG kit and advancer etc is the best for a 2002 Vitz

    Solution: Vitz Acceleration and Breaking Issue on CNG

    From Landi Renzo : CNG conversion of Vitz 2007

    Looking forward to your comments

    Thanks for the input. I'll ask the dealers here in Islamabad about both of these today.

    One more question, whats the capacity of the cylinder are you two using? Do you have one cylinder or perhaps are using two or more small ones combined. I was suggested to go for the 40 one.

    I also own a 04 Vitz FL, this car (vitz) is very unseccessful on CNG. The Engines performance starts reducing day by day, it also shows a sign on the metre which states that the fuel is not the correct one.
