i'm not a mechanic but what type of PASO are you installing? on my roda deco there was a control box that reads the RPM that you set the shut off limit on.
if you aren't prepared for people to chit on you, and calling you and your beliefs down perhaps the internet isn't a place you should be on. cause no matter how much you try you can not win a argument on the internet, especially if people have figured out how to get under your skin.
