Web by understanding the technical specifications and measurable data associated with engine fuel trim, you can perform a comprehensive diy engine fuel trim test and diagnose any issues with your vehicle’s fuel system. Web a tuner is going to be looking at your mustang's fuel trims to see what the engine is needing from the fuel system. 1 above shows the fuel trim Web the who, what, why of fuel trim data. Web depending on the signal voltage value, the ecu will alter the pulse width of the injectors to either add fuel to the air/fuel mixture, or alter the injector pulse width to subtract fuel from the air/fuel mixture, and it this process of adapting the injector pulse width that is. Web fuel trims are a neat mechanism employed by auto manufacturers to reduce the sensitivity of fuel management to operational deviations. Changes in o2 sensor voltages cause a direct change in fuel. A powerful diagnostic tool 2. Web fuel trim readings can be very beneficial in diagnosing problems in your engines fuel deliver, air intake, or ecm. Web the fuel trim parameter identifiers (pids) on the scan tool are telling you how the ecm is adjusting the fuel injector’s “on time” (pulse width) in order to add the correct amount of fuel based on that measurement.
