We offer two different systems. The DieselFlex system will operate on any turbo-charged diesel engine. The Dieselblend system will operate on any diesel engine that has an electronic control unit on it. The Dieselblend technology integrates with the OEM's electronic control unit for that engine. The DieselFlex does not integrate with the OEM's electronic control unit. It's totally independent. It works off of turbo-boost pressure and exhaust gas temperatures.
