Spedo calibrate..

[camma83]

Can i calibrate my spedo with xcal2? because it is bothering me that it is off, i just noticed it yesterday, when i was driving home from hunting, its .1 mile off doh

Yes, but if you're chasing 0.1 MPH, there's a clinical name for that: OCD.

no every mile its a 10th off i had a typo my ooops

Check your tire pressures first. Speedometers should not spontaneously get out of adjustment.

It got out of adjustment when i installed the tune file, i believe so i need to check my gear ration and tire size in the tune i believe so i can get my speedo correct again, I think my truck has 4.10 gears under it but i can't be sure so i am gunna go out and craw under to look at my tag that is on attached with a rear end bolt is
V330L
10 88 4E06 lets see if i can find that on here thanks for the quick replys MAKG

if it has the origional axles, you can look at the door tag for the axle code and check it here http://www.therangerstation.com/tech_library/Axles.html

dude, i wish i had time for that kind of insignificant stuff. i agree with MAKG thats borderline OCD. i have to assume you went for say 225s to 235s or 70's to 75's. if its reading .9=1mile then look at it this way, if you put 100000miles on it you will be selling it with 90000 on it. good luck!

gearing doesnt matter, just tire size.

1/10th of a mile off is a 10% err. that means at 70, your actually doing 77. worth correcting IMO.
