This three-day course helps participants learn how the electronics for CNG conversion systems communicate with the OEM PCM, pre- and post- installation setup and gain an understanding of both dedicated and bi-fuel system CNG components and all safety issues related to the fuel systems.

The number of vehicles powered by natural gas is growing every year. Mandates such as the Federal Energy Policy Act require most large fleets to include alternative fuel vehicles (AFVs) in ever-growing numbers.
