Yeah, my HUD reads 72 with analog at 70; but at lower speeds, HUD 25, analog 26, go figure, seems like different algorithms in the computer.

3. (need long arms for this) Reach around outside and grab the numbers of the HUD where they're floating in space, and firmly grasp them so they can't change.
4. Carefully, with your right hand, bump 'accel' on the cruise control twice to increase your speed by 2mph, but don't let go yet!
5. After the analog speedo reads 55mph, let go of the HUD numbers outside. They should be in sync now.


So in a sense.. there'* no way of fixing it? I my cluster would read faster up to 100kmh than its dead on with HUD till 120kmh.. then it slows down more then the HUD when I'm doing 127 kmh it says I'm doing 122 KMh. I trust the HUD more as I had a few different cars set their cruise control at certain speed and the HUD always seems to match everyone else before the cluster.

Your gauges may be off. The needles can move on their "axle" (for lack of a better word). When you pull apart a cluster, it'* a lot of fun to get these right.... Mighta slipped just a little over the years etc. But the fact it'* not a constant 3mph for example would lead me to believe otherwise.

A HUD is nice for calibrating them too, but i've got mine down based off of shift points and a new nissan.

The City of Lakeville puts up speed boxes that display your cars speed from radar, and my HUD is the accurate one, the speedo'* off.....I don't really think there is a way to fix it, Jason'* idea would work if the setup was linear...but since it'* not, realigning the needle on it'* mount would only make it acurate at certain speed that you did that for and then the rest would be off by even more or less depending on how it was to begin with.

I've used those boxes to double check it as well. My Mtn bike is just right as well.

I think i mentioned something if it'* a linear problem you can adjust the needles themselves. But if it'* 1mph off at one point, and 5 later, don't bother...

Hey I dunno. They had it on 170th and i was doing the loop around the area i have, and It got me. I've had that Bike above 45 going down the bluffs on the Wisconsin border....(speed limit at the time).



I know cops have to have calibrated speedo'* if they use them to record your speed. How do they calibrate a speedo? In the PCM?

Mine are dead on to each other.

But the owners manual does say they can be off by at least 3mph @ 70 and this is 'normal"
