You must first realize that there is a major difference between a dealer "Scan Tool" and an OBDII tool. OBD (On Board Diagnostic Second Generation -i.e. post 1996) refers most specifically to emission controls. While the more advanced ones can look at certain manufacturer parameters (as allowed and published by the manufacturer)they will not hit them all. YES the ECU records maximum events such as top speed and top RPM and these can be "scanned" off the ECU whether you disconnect the battery from the car for 1 hundred years!; don't kid yourselves. If you'ld like a very good home OBDII monitor check:

You may also want to go to Amazon.Com and check out a book called "Everything you want to know about OBD-II".....
P.S. It don't come cheap

So what is the bottom line? I don't particularly want the dealer to know my driving habits, so how often are these reset by the ECU? After every 40 drives? Or never?

Wouldnt losing the timing belt/chain (in interference-type engines) have the possibility of bending valves?
