Many, many years ago I was shown by an auto electrician how to "manually" re-set the speedo by disengaging the cogs and re-setting the mileage without the numbers being out of alignment (tweak of the trade you might say). No my lips are sealed! I was also shown in more recent times the ease of turning the speedo setting back using a common tool-and yes the numbers can be lined up as though it had never been tampered with. Again my lips are sealed-but it does involve a little bit of tinkering afterwards. The Japanese (or Importers) are simply amateurs when it comes to this sort of naughtiness so it's no wonder they get bagged for it. The most common thing in the bad old days was simply to disconnect the speedo cable from the speedo and hope the car in front was within the legal limits! Regards Gordon. P.S. no PM's please I have my squeaky clean record to consider-such as it is! So what happens to a speedometer reading if I take all four wheels off the ground and run it reverse gear for a week or three? What would happen to a hubodermeter?	Sweep (90)

546173	2007-05-02 07:38:00	Many...if not most newer cars have the mileage in the ECM..where it is stored and tested against an E-Cell...to make sure there is no way to modify the readings..at all! There is no way to spool back an odo on most electronic cars/trucks in the US. Uhuh. In my searchings I came across a couple of sites telling you exactly how to do this. ANd one that didn't but went about dodgy dealers and ways they get around it. Not posting any links of course. Anyway its irrelevant, we fixed the problem which was the idea. Of course it will probably need a speedo replacement soon but that can wait until the diesel tax is due again.	pctek (84)
546174	2007-05-02 07:39:00	So what happens to a speedometer reading if I take all four wheels off the ground and run it reverse gear for a week or three? What would happen to a hubodermeter? Since digital speedos are run on a toothed cog (tone wheel), and they don't care which way the wheel turns, any reverse will be seen as over all miles traveled anyway . It just won't matter . NOW . . . a HUB-O-METR© is a different thing altogether! They are mechanical and I guess if you were devoted enough and silly enough to burn all that fuel, you might be able to make one run backwards . . . but why not just put it on the other side of the vehicle to turn it the other way?

You would clock up even more Km. It works in both directions to add to the count, otherwise people would run the hubodometer on the left side wheel for a week, then on the right side for a week and save a parcel of money. taking the car to the northern hemisphere won't save any K's either. Accelerating it beyond the speed of light may work, but could involve certain difficulties of a practical nature	R2x1 (4628)

I know that you cannot get the BCM, the ECM, the DTCM and the CCM to establish a legal handshake if any of them or any of their emission-control or safety device components are modified, missing or damaged in any way . The system's too foolproof and it's not that many fools haven't tried . In vehicles with digital dashboards and digital nacelles . . etc . . the true mileage is stored in a minimum of three places . . more like four! . . . . and if ONE of them goes bad . . . it CAN be replaced with the correct dealer's codes and programming . Even the batteries are digitally signed on some vehicles too . If the mileage does not get a three-way concurrence, then the digital devices . . . and maybe ALL of them with read-outs, will switch on VOID VOID VOID in the display(s) . Seen it . . been to seminars on it . . it is foolproof . . . by the factor that it is 'way too complicated to mess with . If some Medieval "auto mechanic" tries to mess with these sorts of systems, I don't want to see how they are going to face a customer who just had his whole new car voided by the village idiot . BTW: the new Chryslers have another ploy . . the dashboard circuit boards and cell-modules are all light-frequency sensitive . If you open the display or a black box-type unit in an ambient or fluorescent or incandescent or sunlight area, they automatically VOID . They have to be opened in a controlled frequency-lighted area for repairs or component replacement . There are three co-resonant frequencies that must be used simultaneously with a single carrier . . which change with every eight hour time factory shift and production Julian date . The insurance companies, the Department of Transportation (USDOT), the vehicle manufacturers and the warrantee underwriters all insisted on the fool-proofed-ness of it . Your part of the mission Mr . Phelps, if you should decide to take it, is to find that correct frequency and return with that information to your Mission Impossible operatives . . . . . . . . . . . this tape will self-destruct in 10 seconds . YOU will self-destruct if you believe any of those clowns on the internet if they offer quick and easy or even complicated ways to screw with the mileage on the newer and sophisticated systems out now . We ain't talking about pre-2004 vehicles here . . . or garden tractors, or wheelbarrows, or tricycles, or baby buggies or mopeds or flying squirrels .	SurferJoe46 (51)

They claimed that hubodometers, in particular those fitted to logging trucks and trailers, read high when run over dirt roads. We were unable to verify those claims. They were really all part of the truckies objections to the charges. However the cunning truckies found various ways of cheating in those early days. It has to be realised that there is a pendulum in these meters which prevents the dial and its distance display from rotating with the outer case. One method was to drill a fine hole in the hubodometer, and using a hypodermic inject glycerine, which being clear could not be seen through the glass. The hole was then sealed up. This caused the interior mechanism to rotate and reduced the meter readings. It was easy to see which trucks had doctored hubodometers just by looking to see if the dials were turning as trucks went by. Another method, which we also discovered during tests, applied to the larger diameter 'Engler' hubodometer. This instrument was getting on for twice the diameter of the popular Mechanex and Veeder Roots. If the Engler was mounted about 13 -16 mm off centre, the interior mechanism tended to rotate by an amount which reduced the distance readings by about 5% or so. It was not uncommon to see trucks with Englers whirling around well off centre. Yet another trick the truckies got up to was to have their tyres built up with an extra layer of re-tread, thus causing the meters to read lower. This is where we get to pcteks ute reading 10% high. It would be a good idea to check the correct tyres have been fitted. It sounds as though someone could have fitted smaller tyres at some time for cost savings.	Terry Porritt (14)
