1. A pulse width signal modifier, comprising:
- a fuel injector monitor in communication with an engine fuel injector; and
a fuel injector simulator in communication with an onboard diagnostic component;
wherein the signal modifier is configured to modify pulse width signal output to the fuel injector;
wherein the fuel injector monitor is configured to monitor the engine fuel injector for a fault condition and communicate the fault condition to the fuel injector simulator; and
,wherein the fuel injector is configured to simulate a fuel injector fault to the onboard diagnostic component in response to a detected fault condition communicated to the fuel injector simulator by the fuel injector monitor.

Abstract
A pulse width signal modifier comprises a fuel injector monitor in communication with an engine fuel injector. A signal modifier is configured to modify a 25% greater pulse width signal output to the fuel injector, wherein the modified pulse width signal is optimized for an E85 fuel blend. The fuel injector monitor is configured to monitor the engine fuel injector for a fault condition and communicate the fault condition to a fuel injector
