Abstract
A method comprises detecting a status of a transfer pump for transferring fuel between a first fuel source and a second fuel source; receiving a fuel trim value and a vehicle operating parameter; and calculating a fuel composition of one of the first fuel source and second fuel source based on the fuel trim value, the transfer pump status and the vehicle operating parameter. A control module comprises a secondary pump transfer module detecting a status of a transfer pump for transferring fuel between a first fuel source and a second fuel source; and a fuel composition estimation module in communication with the secondary pump transfer module, receiving a fuel trim value and a vehicle operating parameter, and calculating a fuel composition of one of the first fuel source and second fuel source based on the fuel trim value, the transfer pump status, and the vehicle operating parameter.
