In a word, Big.
But in the end, it really does not matter. Ed and I have
found that after calibration (compensating for all the cumulative errors), the
flow reading error under cruise conditions is insignificant. It might be
intellectually gratifying to know how much error there is in all 23 sources
but that would be time spent not building and not flying. A bad
trade. But if someone wants to hunt them down and report on them, I'll
listen with interest!

Injector flow rate mystery solved
Guys, sorry for the interruption....
How much error is really being seen?
Back in my early days at Bosch GmbH (I worked in the IC Center in
Reutlingen, GErmany) on the fuel injectors, and with the BMW system on
calibration. It's been a while, but at the time we had come up
with something like 23 sources of errors on "pulse width" vs. "fuel flow
measurement".
Sorry for being such a dummy, but I'm having a hard time trying
to figure out just how much error is involved, and under what rpm
range (idle, cruise, high speed cruise, WOT).
