Sure but if you have a working gauge you can also point your phone at it and record the gauge while making a quarter mile run or blasting up a long hill. Then play back the video and see what is going on.
I'm starting to use video for a bunch of stuff these days and I'm finding it to be really valuable.
I started doing that a couple of years ago so I could
read my LM-1 and the tach.. worked out great.. I showed
my buddy that and now he will try it.. he has had my
LM-1 long enough to at least try it... LOL.. doesnt
matter to me.. now I have 2 data logger
