Thanks. My comment was in response to yours on the constant demand for E85 vs standard. I brought in throttle position as a way to illustrate imposed demand that is common regardless of the fuel.

Volume of dispensed fuel is not dictated by the max injector flow rate - it is a direct response to the input of the throttle. The max injector flow rate is a limiting factor used to determine the maximum volume of fluid it can dispense in a given time frame.

I didn't know that E85 requires 48% higher flow. Thanks for that. These are figures that are useful.
