so YD is installed and love it.....still getting some kinks out...

first question...in the RPM setup page it is asking "pulses per revolution YD will see per one revolution"....the dyno uses large truck rear ends so...... is it revolution of the brakes or the rollers?  as their RPM is different..

in the "speed and distance" setting I reduced the 42 inch roller diameter to 19.xx to get the speed to calculate correctly......or should I increase the RPM wheel trigger count to 66 from 30? 

we are also having problems with HP reading 3x high and wondering if this is contributing to the high HP numbers..
