Aftermarket Air-flow meter(mass or CFM) for Honda/Acura?
Anyone know of any air flow meter out in the market that can be installed or put on a honda/acura to monitor mass or CFM air-flow? Not talking about MAP pressure sensor. I need someway monitor CFM, kg/s, or any other unit of mass air flow on an RSX-S while the car is on the dyno. Thanks for any info anybody.

A bunch of old Bosch fuel injection systems used a door style airflow meter. It was they type that moved a door and the hinge was attached to a potentiometer. Measure the resistance and you know the volume of air going through. The problem would be finding out the conversion of reading to air quantity. The meter could be gotten from a junkyard and then use flex hose to put it in the RSX air intake. I don't know if this helps any but maybe it will send you or someone else in the right direction?

If you just want to use it to measure airflow for your own benefit, any will do. The chief concern here is to find a way to properly use the MAF sensor. Specifically, the MAF sensor must have the proper voltage applied to the proper connection. And the output signal must also be read from the proper connection. All of this stuff can probably be found from the manual from whatever car the sensor came from AND from measuring input voltage on the given car. More difficult is going to be interpreting the sensor output. Calibration data is going to be pretty hard (if not impossible) to come by.
If, on the other hand, you want to convert a Honda from speed-density to mass airflow metering, good luck!
