How to use LGC's Products? For greeners, we recommend you the Easiest and fastest way to start from Zero (Take 4cyliner CNG injection system for example):
1. Check visualized installation diagrams from LGC to have a general view of how is the full system connected together
2. Check 4Cylinder Gas ECU wiring diagram for the system to see how is the electronics wired
3. See Installation pictures for reference
4. Study the installation manuals: “LPG CNG Sequential injection system kits installation manual.pdf”, “Mach Pro ECU Programming Guidance.pdf”.
To see how to program the Gas ECU--mainly to reach a proper air-fuel ratio for cars of different power

5. Start your conversion on a car and contact LGC for guidance if questions during installation.
(Installation of other gas systems from LGC: take the above steps as reference.)

Propane and methane system (LPG CNG System) gas conversion kits on gasoline cars from LGC:
Sequential injection system kits, two types: suit to 3-4 and 5-6-8 cylinders electronically controlled sequential injection cars;
Propane Methane Normal Suction system Conversion kits suit to 4/5/6/8 cylinders injection cars, EFI as well as carburetor engines; Mainly for cars older than 1990's, for newer cars, we recommend injection system, better performance;
Do not suit to FSI(fuel straight injection) engines, nor diesel engines either.
