When your speedo is registering 174.61, you are actually going 160.93. A difference of 8.5% FOR 2003 -2006 OR 7.5% for 99 – 2002.
If you are using 17/43 gearing, that's a 7.5% shorter gearing than stock gearing. In addition, ALL factory speedos have a factory speedo error (always reading higher than actual speed), and that ranges from 3% to 10% .
Therefore, when using a Speedo Healer to correct your speedo on your ‘99, you need to correct by the factory speedo error as well as the actual shorter gearing. Your total correction factor would be 7.5% (your 17/43 gearing) + the factory speedo error (use a nominal 7.5% factory error) for a total correction factor of negative 15.0%.
I hope that helps and not just infuriates. Nothing is just 'plug and play' really, is it? Edited by: glen66 at: 3/7/06 7:41 pm
