Tire Calibration
1) Locate the 8 pin dip switch on the re-
speed shown (Figure 6). Each dip
switch combination will adjust the
speed by a percentage.
2) To obtain the percent changes in speed
refer to the Calibration Chart A on the
following page.
3) Find your old tire diameter on the left
column. From there go over to the new
tire diameter, the cell you come to
refers to your percent change in tire
size.
4) Next refer to the Dip Switch Chart C
on the following page, look at the
percent change to find the dip switch
settings for the right speed
compensation.
5) The same method is used for a change
in gears. Just refer to the Gear Ratio
Chart B.
6) If the vehicle has new tires and gears,
find the percent change from both
charts and add them together.
