That auto update is interesting. The ECM separately receives and stores the mileage, so the cluster must grab a delta from the ECM on powerup. So far I have identified one message from the ECM to the cluster and four from the cluster to the ECM (which send the ECM the indicator status).

Those extra bytes can be override somehow when the odo gets reflashed though....

Is there any companies in your area that do odo reflashing? I was thinking of paying you to get it reflashed by a company and do a trial run to see if the odo is functioning correct kilos/miles traveled.....

I can do it here through Speedo, but just in case there is any adjustments that need to be made to the cluster itself, it'd be easier and in your hands already to take a look at and do.... (just a thought)
