DIFFERENT TYPE OF CNG KITS

A closed loop CNG Kit system is one where the O2 sensor or lambda sensor in the exhaust gives feedback to the ECU controlling the CNG gas flow, and tells it whether exhaust emissions are within permissible limits or not. The ECU then regulates the gas flow accordingly to prevent too much pollution.
For better mileage and smooth performance

An open-loop CNG Kit system is one where there is no feedback taken from the O2 or lambda sensor in the exhaust, allowing the car to accelerate and inject more gas at will, without the lambda sensor acting as a nanny.

Sequential CNG injection kits are a much better option for your car. This is because the gas flow is controlled by injectors that directly fit into the intake manifold next to the petrol injectors. Gas flow is monitored and adjusted electronically by a separate ECU for CNG, just like how the petrol ECU controls petrol flow. Sequential injection CNG kits can be installed only on vehicles that have electronic fuel injection systems.
