2009 M696 - when i switched out my ecu for the racing ecu, the instrument cluster displayed the mileage on the bike
(in kilometers
of course, but that is another issue).
I thought by switching ECUs, all data would be lost. Where is the memory located? Is there a memory chip in the instrument cluster? Where does it draw its power from since the data remains after a battery disconnect? Is it like a 'flash memory'?
Curious minds want to learn?
Dunno what kind of memory it is, but yes, the cluster remembers the mileage, even without power.
