People have crapped in their pants when they were young too. Doesn't mean that they always should. IMO it is easier to see exactly what is going on when you have a screen shot of what the computer is doing. It is also a lot more precise than say reading plugs when you can see what the O2 sensor is saying. I believe the way to tell if your Jetski carb was "right" was to take it to the middle of the lake, replace the plugs with fresh, start it up, WOT it and read it. Does that tell you idle, mid range? Nope. Just that it was "right" at WOT and therefore MAYBE right at all others. Way too imprecise for me. In my car, I can datalog and see what it is doing. We can also make adjustments to the curve at the right points instead of a "one size fits all" solution. Also checking the carb is way too subjective for my comfort level. I'd much rather have a screen output that shows me as opposed to what looks, sounds or feels ok.
