Acoustic Tachometer (RPM)

Acoustic Tachometer (RPM)


Calculate the rpm, depending on the engine sound.

Through the calculation frequency, the sound is analyzed to determine the revolutions of an engine.

It is necessary to indicate the characteristics of the engine prior to reading.

May not work on all engines. It works worst with engines with the exhaust sound very muted and mechanical noise engines (air cooled engines).

It is normal to show some value even if no motor function.

Didn't work My Buick is too quiet. Great idea though. Will try it again when the muffler falls off.

Completely random readings I tried to use this to set the idle on my single cylinder DR650. I used the correct preset but the app displayed random RPMs. I tried moving the phone all different places, including a half inch from the end of the exhaust, but the app still wouldn't give a steady reading.

Terribly inaccurate. It reads high by 200-500 rpm. Un-installing!

Inaccurate Reads 1500 rpm slow on average but jumps all over at random as well. Needs improvement.
