Can anyone tell me if the speedo and axle adjust in the Predator actually changes inputs to the tranny, engine, ect, or does it just change the readout of the speedo itself?
Thanks

The transmission doesn't care about mph, only the output shaft speed.

If memory serves, the speedo, and the ECM data are adjusted.

FYI, the predator allows for a nearly infinite assortment of tire sizes. I haven't looked into the largest or smallest sizes, but it can accept tire widhs right down to the mm, and aspect ratios in the single digits. In other words, 264-74-16 can be entered as well as 265-75-16.
