Hi all,
Until I get either my speedometer correction module or new programmed chip I'd like to know if there's a simple calc or way to know what correction to make for my speedo reading (having switched from 3.27 to 3.73 rear gear).
If no calc., can anyone give me what speedo reading to look for to go typical speed limits around town...say 35, 45, 55 and 65? Thanks!

The correction factor is .877 rounded to the third digit. Simply take this value and multiply it by the indicated speed to get actual speed. Dividing Actual speed by .877 will give you the indicated speed. This will get you the correct within 1MPH.
