Easy Speedometer Calibration

Today I discovered that it's fairly easy to remove the bezel (trim) and lens from the front of your gauges. You can then gently pull off the speedo pointer and press it back on at any desired point. My speedo was off by 8 mph after I installed big tires, so I moved the speedo pointer and voila! Problem solved.

Re: Easy Speedometer Calibration

That only works at a given speed , since the runout on the gearing change is a percentage , not a given ratio . If you reset it for 55mph , it won't be accurate at 70, or 30 ect....

Re: Easy Speedometer Calibration

Okay, I'll buy that. But isn't it going to be at least close to correct? And isn't it about the only way to correct a low speedo reading?

Re: Easy Speedometer Calibration

Dont' get me wrong , it will be close, but don't even consider arguing with a cop over speed . Like a Zuk would ever get a speeding ticket . The only real way to fix the speedo is to regear the axle ratio's , or regear the speedo gears in the tcase . I wish some aftermarket would handle them like all the other makes .

Re: Easy Speedometer Calibration

Amen Brother! You would think that with all the BIG tires &amp; wheels being sold to Zuk owners, that someone would be making the corrected speedo drive gears for them. (Hmm.. sniff sniff, I smell money!)
Now why didn't my picture work? I'll try again...

Re: Easy Speedometer Calibration

speedo shops can make you a re-gear box that goes in-line in the cable. - last time I looked, they were abotu $100 canadian, but once youve got one, you can change the internal gears to correct for any tire/gearing combo in about 60 seconds.

Re: Easy Speedometer Calibration

What's a speedo shop? (We don't have 'em here.)
Anyway, my "fix" was free!

Re: Easy Speedometer Calibration

LOL , now that it's been mentioned , we have a speedo shop nearby here . I should talk to the guy and see if something can be done at a reasonable price . Anyone else interested?

Re: Easy Speedometer Calibration

Surly: free, well ok - but its not exactly a 'fix', more like a workaround. just try getting it through a mechancial inspection rigged like - instant fail around here.

sarge - there's 2 types of correction boxes: fixed ratio, and quick change. fixed ratio are cheaper, but if your local shop can manage them, get the quick change type, then any time you change tires/gears it takes you 60 seconds to recalibrate. FWIW, the ones I've seen have used Ford internals, as it seems they have the best selection of speedo correction gears. ( Corvette chris, for example, could have 2 sets of gears, and swap speedo ratios to account for his little commuter, and big trail tires)
