It looks like it is controled/memory held by a big surface mount chip on the back off the board.I have noted my miles and the new clocks and when the converter is fitted the new ones will count in miles.It will make the mot's etc look funny as it will drop 100k but as i am not intening selling not to worried.I realy like the look bit weird when i first took it out and got to remember the red line is 7k not 8k
