Correcting speedo error
A GPS is as accurate at calculating your vehicle speed as is a 'certified' speedo in a police car. So when the speedometer in my 2006 Liberty was registering 107 kph when the GPS was showing 120 kph, I mentioned this at my next service interval. The mechanic came up with a relatively easy fix. He re-programmed the computer to make it think I had different sized tires on the car. He got it dead on. However, the odometer still registers less kilometers than the GPS records. I have verified the GPS odometer with the markers along the highway. Can anyone confirm that electronically altering the speedometer reading would not necessarily change the odometer as well? Thanks |

That would be odd, but there 'could' be two different calibrations in
the computer program. I doubt anyone here has a factory manual for a Liberty to tell you for sure.

Depends on what got reprogrammed. Sometimes there are different offset values for the spedometer and odometer, both need to be changed.

I even pulled the needle off the speedometer on my old Cherokee to re-adjust the speed to match a radar gun that was being operated in the passenger seat by a police officer. Since I got my Liberty CRD a year ago, I have kept track of every drop of fuel put in the tank. I use K-Jon Vehicle Record System that calculates among many other things, my KPL, or kilometers per litre. I then take that figure & go to http://www.onlineconversion.com/fuel_consumption.htm where I convert it to miles per gallon (UK) which is the same as 'old guys' used to use in Canada. It was only after I drove back to the Michigan NASCAR race on Tuesday that it came to light that I HAD to be getting better fuel economy than VRS indicated. I drove round trip 588 km and still had 1/4 tank left when we got back to London. This was according to the vehicle odometer. However, the GPS said we drove 658 km. I have since checked known distances and the GPS is dead nuts. The vehicle odometer is approx. 12% off, for talk-sake. Of course, that means that I will theoretically be able to drive 12% further before my warranty runs out! However, I think I'll mention this at my 30K maint. visit. If they think it warrants fixing, then let them find the solution. If they are content with the current situation, then so be it. For the record, my KPL on that trip was 9.79, or 11.0 if bumped 12%. That converts to 23 mpg / 25.9 mpg US. - OR- 27.7 / 31 mpg Canadian. I don't think that's too bad for driving 65-70 mph for the most part. |

Correcting your speedometer/odometer to either more accurately or even less accurately isn't in any way shape or form illegal. It is only if you alter the odometer reading to indicate a lower mileage than accumulated. Grey areas possible in somve venues if you intentionally alter the speedometer/odometer to accumulate waaay less mileage than is being done. Further grey area if after having observed an odometer that is overly accumulating you alter it backwards to indicate the actual mileage--in some instances lawsuit level grey area if it causes your warranty to expire early and you are using stock tires and running gear. Dunno if anyone has collected on one of those lawsuits, but they have been filed where there appears to be a pattern of readings in the wrong direction. |

Correcting your speedometer/odometer to either more accurately or even less accurately isn't in any way shape or form illegal. It is only if you alter the odometer reading to indicate a lower mileage than accumulated.
