I don't get into the Instrumentation sub-forum much, living in a pre-OBDII world. but I noticed this:
Just A Car Guy: smart way to see if the mass air flow sensor works
Rather than adapting a light-plane pitot tube, couldn't the output from a mass airflow sensor be read via an Arduino input and compared to road speed? The front face of a rear view mirror might be a good monitoring location, with an annular outlet. You could have one on each mirror and DIFF them for crosswinds!
