I just performed a firmware upgrade on a p4515tn using the HP Web Jetadmin software. After the upgrade, the engine cycles count have been reset to 0. If I print out a config page, it still shows the proper "Pages since last maintenance" of 185,587.
Other printers that I've upgraded have not had this issue. Does anyone know what went wrong? This kind of sucks, because now the HP Web Jetadmin software doesn't show the proper count along with the other 39 devices in the list.

As a rule of thumbs you should always print config pages, consumables status page and usage page before doing any reset or upgrade because it is always a possibility that something gets erased or modified.
Having all the pages printed out, allows you to enter the service mode and reset the values that got lost/changed during the resets or upgrades.
Now you are stuck with it.

I guess that means that I won't be able to schedule off-hours firmware upgrades. Perhaps I'd be better leaving well enough alone.
In this case, I'll go into maint mode and change engine cycles (if I can figure that out) to close to what they should be. It's more so I can track pages printed in WebJetadmin, which only has an "engine cycles" column.
