It's not "calibrated data" if you're just guessing. A mm3 value in the ECM is a calculated value derived from sensor inputs from the driver compared to sensor outputs from the drivetrain and motor. The calculated value used by the ECM is only a reference point to get the engine to respond to driver inputs, but it is calibrated for control based on factory specifications. There is no reason this value needs to be derived from "calibrated data" as long as the values the ECM's calculated mm3 value is refrencing are "calibrated" to reflect the increased actual fuel flow numbers or desired fuel flow numbers. A factory calilibrated computer might never desire flow above 100mm3, but I can make it flow 150mm3 by increasing the parameters the commanded 100mm3 value references to get 100mm3 of factory calibrated fuel. The ECM does not need to know an actual flow value, because I have control of all the values the commanded flow value has control over.
No kidding, And guess what, its real nice using injector flow data to do this! Do you need flow data no. Can you just poke in numbers on a educated guess of course.
Wonder why Bosch, Nira or any other ask for a injector to flow to simplify building the energization table?
Overlay the flow of a stock nozzle on your modified and all the sudden it becomes easy to see how even a hacked ecu is going to respond without even starting the engine.
