It would be great to have compressed files with real-time measures
so that everyone can process them as he wants.

I'll have that soon (in m3/seconds).
I'll do that by monitoring injector opening, RPM and MAF signal
in close loop mode. I'll do that with a Hitachi hot-film MAF on
a 1.8L 130hp atmo engine. Then I'll try to calibrate a Bosch
hot-wire 280 212 019 MAF (from a 2.3L 150hp saab atmo engine).
