CNG related problems

[khurramshamim]

I have Cultus VXRi 2007 with Lendi Renzo CNG kit (not factory fitted) with 50 KG cylinder. Giving 120 KM (max) on CNG with A/C, and 140 KM (max) without A/C in city. Is it usual mileage with this configuration ? Note that car has recently checkup by Suzuki showroom and after spark plugs and air filter change, fuel mileage is still same.

Need help with City 99 Carby.

On petrol car runs like a dream. On CNG it takes hours to reach 60. With 5 passengers it doesnt cross 70. Had the car tuned several times by different people.

Problem still there.

@livewire !
bro keep the swith inb neutral position (with no lyts) till it burns all the petrol frm carb. thn switch to cng.
now heres the proper way of conversion.[ lando renzo kit push button type in carbi cars]
1- if car is already on gas, just push the button twice. ist push will show both green and yellow lyts on n 2nd will turn the gas off and petrol on... thats it
2-if its on petrol, press the push button once and it will show no lyt but car will remain started..let the fuel burn ..after some seconds, car will start missing and engine will shut off. press the push button again once to turn on the green (cng) lyt to convert on cng. it will show some missing for few seconds but will be fine .
thnx

vitz 2005 Auto giving 120km (55L Cylinder) with or without AC in local and long route. What shud i do, its landirenzo recently installed. Emulator i dont know the name but its used for xli, no advancer installed. Occasionally CEL code P0172(running rich) comes up. Unless i hard reset ECU, it starts missing badly on petrol. Someone told me to introduce a O2 sensor emulator. PLZ help

@roms!
bro this problem isnt a simple to tell u exact soloution. however, u shud first go for a computerized tune up, sensor cleanups and ecu resets. thn any further step...

[roms]

thanks fyq, do u know the price for o2 sensor emulator, Toyota guys and nazir autos told me that the o2 sensor is fi9, u need to bypass it or put in a emultor (o2). The car starts missing because of fault code .i.e. ecu cuts down fuel proportion to match AF ratio.
