I somehow suspect you're messing with me here. But I'll bite: the ECU

Irrelevant, but I still think you should calculate it. Fuel pressure and
injector flow rate are relatively constant, so it should be a simple matter
to calculate the average duty cycle on the injectors, right?


Yeah, I'm mostly just yankin' your chain. I'm fiddling with a fuel
consumption calculator device and I'm too lazy to look up the flow rate on
the injectors. I think you should do it for me.
