Just a quicky,
I'd quite like a calibrated speedo on my omega, however most police cars have covered vastly more miles than my car...
Not being a digital display, would i be correct in assuming that the mileage readings can't be adjusted on ex police speedos?
cheers

Nope

so it is possible? I guess its not in the how to guides for obvious reasons!, If so I think Ill get one...

Rob's reply was ........ Nope, it can't be corrected. You're getting into the realms of 'clocking' if you reduce the odometer reading. The only legal time you can reduce the milage on a car is when you put a brand new odometer in the car with zero miles in it. :y :y

And provide the paperwork to show it, plus paperwork to show the original mileage, if you want to be fully legit... :y

Not that worried...
;)
Unlikely the car will have any other owners after me, and even if it does I dont want to reduce its mileage, (no point low miles anyway with nearly full dealer checkable history + some indy stuff too) but to have it what it is now, just with a calibrated speedo.

... just with a calibrated speedo.
Can't really see the appeal ...... :-/ :-/ :-/
but each to their own :y :y

I didn't really understand what he was saying, though I got that bit.... :-[ :-[

Indeed. A calibrated speedo is not necessarily any better than a standard speedo. At some point in its' life it will have been certified to read within a certain tolerance. Doesn't mean it's any more accurate than a bog standard Omega speedo, especially if it's no longer in the same spec. of car.
-
Well, i was hoping it'd be more accurate than the 'up to -10%' standard unit, but appreciate it may not be.
I dont really need a calibrated speedo to know that real speed is 35 when stuck behind those who think NSL means 40 rather than 60, but would be nice to justify my heavy right foot to swmbo ("see love, just trying to make progress and actually do something near the speed limit for a change......")
Just didnt want to add an indicated 100k to the car for the privilidge.

where does it say it's illegal? You're perfectly at liberty to adjust the mileage reading to what you want. The only time that it is illegal is when you've done it to deliberately increase the value of a car for sale - i.e. fraud

You sure? How are the powers that be going to draw the line between 'clocking' an odometer for fraud or 'clocking' an odometer as above?

If you sell it....
I could 'clock' mine to 70k and continue driving it :)
No harm done?

While apart can't the new speedo mileage wheels be moved to the same as the original one?
I once dismantled a Carlton speedo to fix a loose gear so can't be too difficult.
-
I can only assume the need for it is to have a accurate speedo in your Elite?, if its for other reasons, pull the RS Sticker off and stick it on your Elite.
Going back to the Calibrated bit, theres a good chance it would have been calibrated with 15" Wheels and different Diff Ratio, so wouldn't necessarily be of use on your Elite anyway.

if you want a more accurate speed just use a sat nav :y
-
You can clock them as I've got a speedo somewhere in the garage from an Omega with 1 mile on the clock! (I think it had 200k+ on it before I took it to bits!).
I seem to think it was very fiddly though... ;D

Thats actually bad idea, SatNav speed is often off too.....
-
it is only accurate any sat nav on a flat straight road and even then it is a little out as it was built into the sat so the ruskies didnt know where it was/is :y

They actually turned off selective availability, which deliberately introduced an error for security reasons, 15 years ago. GPS can give a speed signal to an accuracy of 0.1 MPH or so if the signal conditions are good and the direction of travel is constant.
Of course, that assumes your sat nav is showing you GPS speed (calculated by the GPS chipset from signal doppler shifts) and not calculating it by comparinging successive positions reported by the GPS, or using the speed signal reported by the ABS ECU.
-
Accuracy of standard ones is actually quite close - usually about 1-2mph over over the entire range.
Satnavs, most are pretty inaccurate, as they try to time between points. You can get proper GPS devices that do work it out accurately.

for a price.. i guess quite a high price :y

No. Any GPS receiver will give you a very accurate speed in the NMEA serial output. What it displays (if it has a display) might be filtered and mucked about with, but will be spot on if you don't change direction or speed and have good signal conditions.

As to this 'clocking' malarky, it's only an offence to sell a car if you know it's been clocked, and it can only also be an offence if you state an incorrect mileage to be genuine. For example I could buy an Omega tomorrow which has done 200,000 miles, whack it back to 60,000 and make up a service book, but if I state the mileage reading is unknown to be correct then I haven't actually done anything illegal.

To clarify fr those that may not understand what Kevin Wood has said, the GPS antenna reports back to the 'computer' (be it laptop, satnav electronics, speed measuring device etc etc) various things in an industry standard format (well, there are 2 or 3 different formats, though NMEA is by far the most common). These packets include not only position, but also direction of travel and speed of travel.
The accuracy of all these devices is improved with the number of fixes the antenna/receiver can pick up.
The problem with your gay little tomtoms etc, is because its used in a relatively hostile environment - in a tin box, behind heat refelctive glass, and to make the unit small, a compromised GPS antenna - your signal is less than ideal. Added to this that the silly little unit is only useful for the last mile anyway, where tall buildings can cause all sorts of signal problems, the software in the devices has to molest the signal.
The likes of Tomtom can make an assumption that you are on a road - we've all driven around new bypasses that aren't on the digital map, and you can be well over 200m from the old road before the daft thing conceeds you are in a field.

I've recently done a back-to-back test between some pretty expensive UK MoD GPS systems and found that the most accurate was my £79 hand-held Garmin unit
