I've vitz 2005 model and I last month I took it to CNG workshop for fitting cng. At present Landi Renzo kit with 55kg faber's cylinder is in my car. I am quite confused with the performance of my car. because initially I noticed almost 125 km avg in one cylinder but later on after initial adjustments it has been reduced upto 95 km (local). Also if three or four persons are in car, it behaved like a car without engine,
CNG mechanic who installed cng in my car, couldn't manage to connect advancer and said that he can't take risk to connect advacer because vitz 2005 has more wires than other cars and it may cause computer program problem.
Please suggest me some good workshop in Lahore to sort out this problem.
Answer to problem number one is that the millage will come down in the summers not just because of the A/C use but also because of the high temprature even wid the same preasure U get less gas in the Cylinder. So dont worry. In the winter the cars which deliver 140 Km come down to around 100 to 105 Km.
As far as the power output us concerned yes Wid CNG U loose a lot of power so this is somthing U need to live wid.
I dont know Y did ur mechanic not fit ur car wid advancer.
It is very important that you get it done as timing has a serious effect on the performance, and now the mechnics are trained so well in wiring, I dont think it shud be an issue.
Take ur car to FTFS Faisal town main road, and get an opinion from thr as they have vast experience of dealing with efi cars.
