Q1: How to know which cars your kits suit to?
A1: If not sure which gas kits form LGC fit your cars, please provide informations:
- What is your car's engine types: (Electronic Fuel Injection) EFI or carburetor, and how many cylinder?
- If wanted to use aspirated system/normal suction system conversion kits: How many cylinders is your car engine? Engine Power in HP or KW? Throttle body diameter?  

LGC provide two types LPG CNG kits:
1) LPG CNG aspirated system kits, suit to carburetor cars as well as EFI cars:  Simple installation, lower price, but performance not good as sequential injection kits;
Generally for those older cars which do not require too high for performance; for newer cars, we recommend sequential injection system:
2) LPG CNG sequential injection kits, for EFI cars only: (Two types) suit to 3, 4 and 5, 6, 8 cylinder sequential injection engines cars: Latest and most advanced system currently, much better performance, more complicated installation and higher price.
3) Kits from LGC, suit to petrol engines only, currently do not suit to diesel engines, do not suit to FSI (Fuel Stratified Injection/Fuel straight Injection/Direct Injection) engines either.

Q4: I want to start gas conversion in my local area, Is it easy to install the autogas conversion kits on cars?
A4: If you can take time to read and follow our installation instructions, have basic mechanical skills and tools, it is not hard for you to get familiar with the conversion; and you will get our help anytime you would like. Quite a few people with nothing knowledge on conversion previously, have successfully converted the cars themselves by vewing our installation info and via our assistance.

No matter the aspirated system or sequential injection system should be easy! Connect all parts (from tank to mixer/rail injector) well and make them sealed (leakage test), then set the air-fuel ratio right to allow the car work smoothly on gas.  

Some ones think injection kits very complicated especially the programming in PC--really? Not after you understand it!
Programming or tuning or adjustment during autogas conversion is all mainly to set an appropriate air-gas ratio to match with your car's power/displacement (which varies in different cars). Injection kits: do this via the gas ECU software in PC, regulator's pressure adjustment, rail injector's gas outlet orifice size; Aspirated kits: do this via regulator's pressure adjustment, power valve; mixer (some kind of mixers can be adjusted).

Q5: Is your aspirated system a close loop system? With stepper motor, lambda controller etc.
A5: Our aspirated system generally do not come with these items.
Open loop system work very well yet, if used a timing advance processor, it will have better performance.
With the close loop items added, the car's performance increase very LITTLE, but making wiring/installation more complicated and costing more.

P.S.: The most advanced gas conversion system for gasoline cars is injection system currently, close loop system is an outdated system, its feedback adjustment function is stupid and rough, which is obsolete yet and disappear soon, you nearly find none of this worldwide now.

Q6: Is your CNG system 3000psi or 3600psi?
A6: All CNG conversion kits in China are of "rated working pressure" 20Mpa=3000pi, although it can bear 25Mpa=3600psi;
3000psi or 3600psi, it concern mainly the CNG tanks, which we generally do not sell.
