The new module monitors driver inputs and vehicle conditions and allows seamless switching between gasoline and compressed natural gas (CNG). The module has custom diagnostic monitors for the secondary fuel and supports standard CAN automotive diagnostic scanners connected directly to the factory diagnostic port.
The system is based on Pi Innovo’s flexible OpenECU M220 control module, which gives AGA Systems the freedom to develop its own software and unique control methodologies with an electronic module ideal for low- to medium-volume commercial and automotive applications.
AGA Systems has achieved EPA certification for its bi-fuel system for General Motors’ light-duty truck and SUV platforms.
“We found the OpenECU tool chain to be very easy to use. We were able to quickly implement changes to our application and test those on a vehicle right away,” explains Aaron Stuart, vice president of engineering and technology at AGA Systems. “On previous platforms, we would have to wait up to three months for software changes. Now we are able to write our own software updates and implement them within hours.”
