Speedo Gearing

(1/3) > >>

Tyke:
Would it be right to asume that if bigger tyres are fitted and the speedo is running at about 10% error from standard then the milage being counted will also be out by 10%?

I heard you can get the speedo recalibrated . . . . . is this also true and who does it ?

Cheers  :wink:

Budgie:
Yes the mileage will be out as well as the speed reading.

If/when you change the transfer box, to a 1.44:1 then the speedo gearing will come back in if you use the speedo gear from your 1.22:1 box.
I think mine reads about 2mph fast according to my GPS.

I spoke to Ashcrofts about this when I did mine and they said that if I supply them with the T-box ratio, type of gear box, diff ratios and tyre sizes then they could supply a speedo gear to suit.
With mine only being 2mph out then I've not bothered though.  :wink:

hobbit:
Use the gps and put paint marks on the dial to let you know your true speeds :wink:

Tyke:
Cool, your a star fella.

I thought that would be the case. I'll keep it in mind when I get to swap the box and make sure the standard speedo gear goes back in.

Think I've thought through everything, now it's just a case of time and money to get the job sorted.
