I used it for nos you should be rich and at wot before you spray. The gauge will show rich green. Then you can watch to make sure it does not turn full on red, which would means something is wrong with your gas noid and you better turn things off quick or start looking for a new engine. That's the only real use. Not really very good at that. Puts on a nice annoying light show and looks like rice if that's your sort of thing. Does about nothing else, no you need wide band and software for tuning, not a simple a/r gauge.
