Yeah, I pay attention. So blow me.

Currently the tach needle is riding just off the top of the 500rpm line - at probably 600rpm or so. The needle used to run at half-way between 500 and 1000 before - which I considered to be a bit high, but lived with. And yes, this is with the engine at operating temperature.

Now does this seem odd? Yeah. And I have no idea why it is so. My guess is it's whatever changes have taken place because of the ECU reset - not necessarily the removal of the HC filter. Or maybe a combo of the two. I don't know. But, the engine idles fine, and nice and smooth. Gas mileage is up a bit. I can live with it just fine.
