i just installed a oz gauge cluster in my es and i feel like the speedo needle is off. after driving so many years u kinda get an idea about around what speed you're at and i can easily tell that the speedo shows a higher speed than what i'm actually at. i don't know how to check how much it is off by either. anyone know how i can fix this problem?

 

When I got a ticket my lawyer told me to go to a shop that does speedometer calibration and is recognized by the court. That's in VA but maybe you can find out who does speedometer calibration for your area. It cost me $85.00.

 

damn i don't know if i wanna spend almost a $100 bucks just for a little satisfaction lol. i'll first try to figure out how much exactly its off by and then see. thanks for the help thou man

 

yes i'll either try to use someone's gps or just have a buddy drive along lol. i just wanna know what the difference is so i can see it in my mind while driving even if i don't completely take the cluster apart and try to mess with it cus it looks good sitting where it is lol

 

yea i'll either try to use someone's gps or just have a buddy drive along lol. i just wanna know what the difference is so i can see it in my mind while driving cus i might not even take the cluster apart and try to mess with it

 

yea i'll try to use someone's gps (its a shame i don't have my own lol) or have a buddy drive along but like sgand said we'll figure this out and i'll keep u guys posted haha

 

yea i don't even know what happend i tried posting earlier it kept saying i caused an error i don't even know how lol and why is it lookin all messed up now with the posts out of order?

 

Is your tire size OE spec?

 

It has nothing to do with the tires.

 

Yeah, drive by a radar speed sign or even have a buddy with you, like you said before.

We'll get this figured out.

 

whoa dude, you somehow broke the thread. lol.

 

wouldnt a bigger diameter make a difference in the reading?

 

seem to be quoting Amby a lot lately.



Besides, his is off because I took the needle off and thought I put it back on correctly. Nothing to do with the trim difference of the car.

 

^^ i think he's sayin since the stock ones are 14/15's and he's running on 17's

 

Yes, a tire's size plays a part in it! The taller the tire, the more diameter...a full rotation takes "longer" thus throwing off your speed.

Yeah, so I have 17's with a 40 sidewall and I'm (I think) 1.5% off.
