Great post, I don't mean to revive an old thread; however, I am in the market to replace my 115k mile old Accord's instrument cluster with a newer Crosstour's. When I saw somebody else on the forums complete this, it showed that the new cluster retained the mileage (from the original Crosstour) after being replaced in the Accord.
Now, my question is, since it's stored in the ECU, why doesn't the cluster automatically display the true mileage?
Has anybody inquired from Honda if it is possible for some sort of flash or update from a Honda tech to give the real mileage? I've heard it is in fact illegal.. Although something tells me that it's only illegal if the mileage is rolled back to something younger than the actual age of the car it is installed to, rather retaining the exact same milage - just on the new cluster, almost as an exact swap. What if somebody is working on their odometer and completely screws it up? Wouldn't they need a brand new one, not showing their true mileage and must have it replaced?
