Odometer is off

[John Dombrowski]

so we tested my wife's turbo's odometer with a couple cycle apps and it is about a mile off about every 5 miles. Do these things need to be calibrated?

 

[Douglas Ruby]

I checked mine and found it to be pretty accurate. I have anothe cycle computer that I calibrated using actual wheel/tire circumference in mm. The two are off by no more than .5 mile in 250.

I use cyclemeter and mapmyride and they are almost identical so i find it hard to believe that they are both off. I will wait to see what my Turbo S shows whenever I get that darn thing and go from there but for now I will go by my apps.

Could be that the setting for the wheel diameter is wrong; that would account for such a large error. You should be able to check that on the console, John D.

Thanks and what should it be set at for the base turbo? And how is it set?

Specialized has each year model computer settings in pdf format, so here's a link to the 2014 Ant+ version; page 26 & 27 have all of the info for a Turbo console. If that's not the correct model or year then use their searchable manual list; just highlight the year, ebike, computer and language and the results pop up below the search list.
