I going to be putting new 20 or 22 inch wheels on my LS v8 sport premium, which of course will throw my speedometer off. I tried googleing on how to adjust it or recalibrate it but turned up not a thing.

So my question is, dose anybody know if there is a way and if so how?


Cheers,
Eric

PS pics are on the way been busy and when the are ready how do I upload them to my Photo Garage

:L

the cm will have to be programmed. For the cost you might consider haveing sct do the job. I imagine the dealer, if they will even do it, will charge just as much or nar the cost of a custom tune.

correct the SCT XCalibrator can correct your speedo.

www.fordpartsnetwork.com (http://www.fordpartsnetwork.com) - Torrie has done alot of these units for LS owners.

I don't think 22's will fit,or if they do they will rub really easy.I have 20" on my LS and they rub somtimes.

For your Speed odometer problem.I tested mine by crusing at different speeds while my friend read out his speed and the difference from 45 to 85 is only about 1 to 3 miles per hour over a normal reading.

use this -> http://www.1010tires.com/tiresizecalculator.asp to show the difference between the stock tires and what you are thinking of using. It gives you the %error your speedo will be out.
