I race mostly oval, stock and 19 turn. I just got the speed control yesterday and was playing with the settings. I understand the "frq"

Can you explain the difference between the Dash modm and the Power level?

Also with the Ensa.......... What does it do? I understand based on what I have heard it almost acts as a power cap. Taking any back flow energy and keeping it from acting in reverse on the speedo. Why can you set it to 30,50,70 or 100? Should you not just run it at 100 all the time? Any help would be great, thank you. So far I love this speedo.
