Sick and Tired of Waveline pumps

[daplatapus]

Ok, so long story short I've gone through 3 controllers on my Waveline 12000's. 1st gen controllers were awesome! But they burned out their poorly designed cooler fans, thus in turn burn't out the controllers.
2nd Gen controllers = very poor pump performance (at least on high head applications)
3rd Gen - no change from 2nd gen (at least the ones I got)

I have to say, there is a definite, audible difference in RPM from my 1st Gen to the other two, so it seems like it allows the impeller to ramp up further.

Now I hear there is another gen that is Apex ready.

My question (because it appears RLSS customer service doesn't like it when you keep asking them why their products suck):
Does anyone know if these pumps are PWM controlled or how to test if they are?

How can I mod something to drive these pumps?
