RPM activated switches are nothing new, but for the price, you wouldn't expect this kind of accuracy! This box has been refined to an exact science. Change your shift point in 100 rpm increments by simply pressing the thumbwheels. No more fumbling around looking for "chips". Repeatability of +/- 1 rpm, means each shift, each pass will be virtually identical. Works with any MSD/Electronics ignition system. (Magnetos too with our p/n PG8 pulse generator)
