    Angry Mehran not speeding at CNG.

    Hello all,

    I have 2011 model Mehran, the problem is that, it doesn't speed more than 80Km/h on CNG. However, on Petrol it easily goes upto 100+km/h.

    What could be problem? The car is totally driven just 1500 kms and 1st free inspection by Suzuki is done but they didn't do any Engine tuning / tappet adjustment etc, they just tighten the nut/bolts and changed gear oil, that's it! So you can say that till after showroom delivery that car engine tuning has never been done so far, even-though it has completed 1500 kms.

    What is needed so that it can accelerate like petrol and on CNG can go upto 100+km/h. I'm not a fast driver but it really really annoying when you keep pressing the full pedal and car doesn't accelerate and give impression that "I can't accelerate anymore"

    Lala CNG hai NOS nahi. Adjusting it for speed will ruin the economy and won't give speed either

    Results are better First it didn't gone over 110 now on road pick is better but as they Say "SAH leti hai a little bit" as my old mehroo had Local CNG with no venturi it was a drilled hole in Carb and one butterfly had to be disconnected so i have habit of pushing car in CNg
    well i know attitude of 3S guys they haven't changed gear oil of my alto and on first tuneup car wasn't responding as it should and tappet adjustment is on 5K inspection and i will have to buy engine oil my self
    just say to them "Pick nahi pakrti " they wil adjust the Gas and it will be fine seriously its a 5 min job but u have to put pressure on them
    i am not allowed to take car to local mechs by family and i agree but i have seen many guys quiting 3s and going for ENERCON CNG tuning
    simply they are here to Rip ur pocked
    Hanjiii Kaa Storeey Eehh !

    Status Update: Today I went to Suzuki 3S and they just adjusted the CNG adjustment screw and it is fine. Now it is easily going upto 80 km/h in third gear

    Thanks everyone who suggested me.

    hi first of all best of all for Merhan ..lol Well i am v much sure that ur mechanic just tune it up in a way that u cant go more than 80 sped so irt wilnt consume more gas and eventually will give u good mileage like 120+km in a cylinder which is quite diffiicult for mehran ....as its avg mileage is 90-100km in a cylinder...
    so now what is solution?

    go to dha suzuki aster motors and ask them to tune it again.
    i kniow they can fix this...when i had mira i use to go there
