brother !
whenever u wanna install a kit,tell me,i'll install it frm my wrkshop,n performance will be guaranteed. insha ALLAH. and for tunning, put out some time on monday evening and call me,i'll tune up ur car frm my wrkshop, i cant suggest u any other mechanic as they charge alot but do a bit, so y dun u spnd a litle and have the same results coz tunning is nt a big work !
2ndly, parts can be also DO NUMBER !
FOR INSTALLATION
u shud hav following factors in mind
1- original made brand of kit
2- best quality cylinder
3- emulator and advancer matching
4- neat fitting
5- results shud be guarenteed.
dekho ! now i tell u the story of cng in engine
engines are not designed for either petrol or cng, actually cng is a secondery type of fuel for engines, we claim often tht car is not running good, cng is not a prmnnt fuel, etc, but did we ever think abt the reason for tht? hav we ever read the manual for kits tht displays" to get better results,drive your car on 2-3 litres petrol after runnig 2-3 cylinders of gas"???
wherever u get petrol it has same formula everywhere ! but cng is different on every pump, u dun know tht wich elemnt is in more ratio and wich is in less ! we just know its pressure , and tht can easily be increased by air, while filling gas in ur car,compare the presure on guage of dispencer with tht of ur car, if there is difference, tht cng station dun sell good gas.and how can u get good results with tht ?
lambda thing has no faeda ! its an optional thing and just increase purity of burning elements ! efi vehicles need advancer and tht shud match and according to need of ur car.
cng needs adjustmnts , so it has variables to adjust, but petrol dun have.
i hope u r getting my point, but if u still hav some doubts, ask me, i'll try to explain more betterly.
thnx!
