ECU mileage lower than Clock mileage


My clock says I have 75500km
But examiner and FiatEcuScan tells me I only have 70900km. Which one is correct?

Also, you see the reprogrammed bit? It says my ecu was reprogrammed once. And it was 6300km ago. The car was already mine by then. I didn't reprogram anything!

So spice things up, my Selespeed mileage doesn't correspond with either readings! Acording to selespeed, the car only drove about 50000km

Do I have tampered mileage? My selespeed was replaced in the past?

Re: ECU mileage lower than Clock mileage

Do I have tampered mileage?
Most probably not. Try to think of it that the ecu records a number of units corresponding to the distance covered. This number then needs a multiplier to convert it to actual distance. The multiplier is different depending on the car model just to make it difficult.

It's discussed here
