Autometer has a new, trick tach that is designed mainly for NASCAR, but can be used on any application. With this tach, not only do you get a high RPM warning, there is also a “window switch” for a specified RPM band. There is also an additional controller that allows you to select your RPM points down to the single RPM. If you wanted a rev limiter of 6523 RPM, you could do that with 1 RPM of accuracy
If your coming off pit road and 2561 RPM is 45 MPH and the maximum speed is 50 MPH on pit road with a 2748 RPM point for that speed, the multi-color and 5 dot system will progressively advance as you get closer to the maximum RPM desired; if you go over the high RPM limit, the face will flash at you.
