EPA Certified and Non-Certified Kits

To receive an EPA certificate a kit must be installed on a specific 'engine class', undergo and pass emissions testing at an EPA lab. An 'engine class' refers to a specific engine manufacturer, engine displacement and associated emissions equipment. The EPA certified kit software is 'locked' and cannot be adjusted for future needs or changes.

A manufacturer’s non-EPA certified kit sometimes has the exact same components as an EPA certified kit but has not undergone the EPA lab test. For non-EPA certified kits, Falcon CNG will 'tune', or program, the Electronic Control Unit (ECU) to provide the proper amount of CNG under various driving conditions. In order for the vehicle to be drivable and to prevent Check Engine Lights (CELs) the tune, or programming, must be performed properly.

Some states require EPA certified kits to apply for the state's rebate program (i.e. AR) and some states do not (i.e. UT & OK). Falcon CNG provides EPA certified kits and non-EPA certified kits depending on the vehicle, customer's requirements and which option provides the best return on their investment.

A big advantage of non-EPA certified kit is that it can be moved from one vehicle engine class to another, an EPA certified kit cannot. If you have one make and model of a truck, for example a Chevy Silverado V8, and buy a different make and model, say a Toyota Tundra V8, then the entire conversion kit (minus maybe a few seals, fittings and hoses) can be moved to the Toyota truck and re-tuned. Thus saving the expense of purchasing another kit.

Non-EPA certified kits also have additional advanced tuning options to customize the CNG operation to meet the driver’s needs such as heavy towing or extended highway driving.
