Where to get car calibrated?

[KillJoy]

I was wondering if anyone knew a local shop that would be able to calibrate my speedometer? Any information is appreciated.

Best bet is to take it to the dealership, IE: if you have a chevy go to a gm dealer.

I had the same problem with my Pontiac I had and couldn't find anyone to help me out. I ended up having to go to the dealership to get it fixed and wasen't cheap either. They had to send away my cluster to get it fixed. When this happens it really sucks.

Dang, I hate going to the dealership for anything.

Thanks for the help!

What kind of car and why does it need calibration? Change rear gears? Tire size?

funny you should mention this
I got in the beast yesterday and the speedo was 20mph fast!?
got in it today...now it's 10mph fast!?

Might be cheaper to get a GPS and use the readout on it

Thats pretty crazy....

well...since the fluctuation, i am led to believe that the speedo isn't cable driven :shrug:

It's a Focus Wagon. The speedometer needs the calibration.

Just drag race with a MSP and then ask him if his Radar Gun is callibrated !

 

[KillJoy]

Haha funny you should say that. The reason I want to get this done is because I was pulled over for doing 63 on 231 by one of CC's finest. I know for a fact that I wasn't speeding because the cruise control was on 50 and I do not speed.

ahhhh take it to the dealership.

 

[KillJoy]

That's what it looks like I'm going to do. I can do anything else mechanical wise on a car but when it comes down to this, I have no clue.

Most newer vehicles have electronic speedos... wasnt sure about Jeeps though. :shrug: Strange none the less though.

Most of todays newer vehicles have the tire size programmed into the Transmission control module. The trans control module then controls the speedometer. If the wrong tire size is programmed it will throw off the speedometer. Keep in mind that all vehicles can have a + 0r - 5% off on this reading

Are you still having speedo problems? Could be a slipping clutch. That would make it read fast. That is how I knew I needed a new clutch on my Beretta.

I've never seen a speedo that was driven pre-transmision. I suppose it's possible but...


Echo, when you first start the car, do the gauges all jump to max, drop down, then jump to operating parameters? If the speedo does this, then it's actually stepper driven and you have most likely have an electrical problem.

If NOT, then you have an analog speedo and the temp probably dropped low enough to thicken the fluid in the viscous coupling within the speedo.

That used to happen every winter on my Grand National and on my 83 Toyota pickup.
