Any domestic injector i ever tested had 14 volts on it continuous and the ECU grounded it to fire it.
The pulse width is constantly changing every other engine revolution and instant FE is not readable without some averaging.
Only need to log one injector's on time.
Calibration to each vehicle using a known quantity of fuel and a known distance is the way to go IMHO.
So it needs accumulate total injector on time for one injector.
