Presumably there is a PWM output, but maybe GMPP did away with it on the retrofit kits (as they did on the e67 kits, as John Parsons experienced). I also know that the new generation of fans the WPM controller is built into the fans, so no intermediate controller (like the C6) is needed.

I have an LT4 and the GMPP controller kit, and a late model CTS-V cooling fan, but we're a month or two from finishing wiring and getting things running. I am hoping that I can reprogram the e92 with HPTuners to do PWM control as it does in a CTS-V - we'll see. Why GM would block PWM control in the crate motor ECUs is beyond me ...
