Cutting 1 out of 4 cylinders is an automatic 25% reduction in power.Correct, and why you may want to expand the range simply, by adding more "n" as I outlined. Well, you're sort-of correct, as 1/5 would be a 20% reduction. Using 1/33 would give an average 3% reduction. 1/17 for 6%. 1/9 in my 2nd example for 11%. Dial-in what you need and works best for your steps, as you could freely adjust both the amount and steps of reduction. Tune it.

Would have a retard limit or something and if its not enough, could be used rolling cut or progressive cut and hard cut if its necessary depending user's config.Here's the reason for the optional 1/n alternative — retard works well for reducing power, but also dumps-in a lot of heat. For the racer in the video it's fine, as he's using much better fuel than most of us on the street. For streeters using det-limited pump gas, randomly dropping a load of heat into a system that is already on the edge of the fuel's capabilities can trip them into detonation or preignition. For those users, progressive power-reduction is a safer alternative without the risks that retard can bring.
