To all you Impact owners out there, why is it that so many good tunes require the power wheel set at 16? Pellet size and velocity doesn’t seem to matter. Makes me wonder what all the lower numbers are for.
FX M3 Tuning Power Wheel

The power wheel at 16 means absolutely nothing. It's the scale on the micro adjust area that matters. For instance if I want micro at 4 I can adjust the wheel to whatever number I want.

power wheel setting depends on what the macro is set at,as both micro and macro adjust the same thing (the hammer spring)
but they do it in different increments.
so the number that counts is the number on the macro adjustment.
for instance,
if i end up tuned and my macro shows 3.5,
and power wheel says 14,
i could start from scratch and turn the power wheel to 3 and the macro to 3.5
and it would still be the same exact tune.
so regardless of the power wheel number,
the macro shows the hammer spring setting,
no matter what the wheel is set on.
so what i do when i tune is,
at whatever regulator setting i choose,
i put the power wheel on 16,
valve adjust out past the 4th line,
and turn the macro up till my velocity stops rising,
then ill bump the wheel down a number at a time until my velocity drops 20-30 fps or so,
then turn the valve adjust in till velocity drops another 10fps or so.
you can then fine tune from there to get a flatter shot string.

Don't forget the valve stop up front, I would say lower numbers are for lowering the velocity, for lighter pellets or closer targets, indoor shooting ETC,

Thirty years of meetings that took three hours and should have been fifteen minutes have taught me well. lolhahaha you beat me to it ,and with less words

I think the wheel you are referring to is the micro and the power wheel is the macro. But yes, that's how I also tune more or less.

So power wheel at 16 does not mean hammer spring tension is maxed out if I understand you correctly?

Correct, look at the micro and the scale next to it. You'll see the numbers. Higher is more spring tension.
