tomanji Posted June 20, 2004 Share Posted June 20, 2004 well the dif in gear ratio will affect your speedometer, and in effect also effect your odometer. just the same way changing tire size or rim size can even switching to lighter or more heavy rims will throw off the calibration of the speedometer. but it can be calibrated.. call around to some of your local shops and ask if they have the software to do it... I cant think of the exact name of it at the momant. Quote Link to comment Share on other sites More sharing options...
