Whats Up all. Well got a speeding ticket today for going 76 on a 65. but i know for sure i was going over 71mph is it possible i need to recalibrate my speedo TKS

 

do you have bigger tires? gears? a little info would be nice

 

I know for sure you were going over 71, you're ticket was for 76.


If you have over/under sized tires, that will affect your speedo.

 

Bet he is running larger tires... most people add bigger tires thus making their speedometer go down. Gonna guess they are 18's @ P285s.

Rarely do people just do gears for stock tires... but I'm an exception. I'm running 4.10's with P235's stock Hank00ks. This makes the speedo look like I am going faster than I really am. So if I am going 55 mph according to the speedo, I'm really going 50 mph, roughly.

 

You need to rethink that one, if you have larger tires than stock- you're going to be going faster than your speedometer is showing.

 

If you have aftermarket tires, it is your ultimate responsibility to ensure the speedometer is not affected.

The court will expect nothing less.

 

Thanks for the correction Manual.

 

I almost agree but a lot states don't require a speedometer. This way poor calibration cannot be used as an excuse. The driver is responsible for their speed with or without a speedometer. This creates a win/win for the revenuers.

 

What kind of vehicle? Some programers have a feature where you can recalibrate your speedo.

I know the diablo preditor has this ferature/

 

Before i re-calibrated my speedometer with the xcal2, my speedometer would say 63 when i was actually going 70. I have 35" tires, and my computer thought i was running 31.5" tires.

 

You can have your speedometer "offically certified" by taking it to a place that does that. I think they put it on a dyno or something... but I'm not sure how much it costs though.
