1. A system, comprising:
- an engine control unit configured to provide a fuel injector pulse width signal;
a signal modifier in communication with the engine control unit and comprising a fuel-type identifier, the signal modifier configured to modify the pulse width signal to generate a modified pulse width signal; and
,a fuel injector component in communication with the signal modifier;
wherein the signal modifier is configured to provide the pulse width signal or the modified pulse width signal to the fuel injector component in response to a parameter input to the fuel-type identifier.

Abstract
An engine control unit is configured to provide a fuel injector pulse width signal. A signal modifier comprises a fuel-type identifier in communication with the engine control unit. The signal modifier is configured to provide a 25% greater, modified pulse width signal to the fuel injector component in response to a parameter input to the fuel-type identifier. The pulse width signal is optimized for a gasoline blend and, more particularly, to an E85 fuel blend.
