What duty cycle numbers are you concerned with?

89% on e50, 94% on e65, so it will keep climbing with higher e%
But, as you have said, duty cycle is not a real measurement of injector open vs closed time. It's calculated, based on several parameters, including injector size. Therefore, if a smaller than actual injector size is entered into ECUTEK (say 650 instead of 1050), and the ECU demands a certain amount of fuel, its going to assume these smaller than actual injectors will have a higher duty cycle. Because 650's need to be open longer than 1050's. Dont ask me why someone would do this, but if this is the case, is it correct that the ECU will report a higher duty cycle than what's actually occurring?
