Just remember to disable your FI system before doing the test………..I have a digital tested that only tests one rotor at a time.

I used a Micromite to sample a similar automotive pressure transducer but didn’t calculate rpm which I should have.
I recall at the time checking the response time of the transducer but cant remember my findings.
I plotted the data in Excel to compare with latter tests. I didn’t calibrated the data. Just wanted it for comparison.
Looks similar to the one I made with a spare pressure sensor and Arduino.
But after that I just used he prop to pull it through the six compressions.
Looks like I could improve my software to not require crank position sensor.
Curious what brand of compression tester you all use on your rotary?
I found this one and thought I might order it, unless you all know of a better one to buy?
