Default Changing O2 sensor - reset ECU too?

I'm going to be changing my O2 sensors, should I reset the ECU in the process? I didn't on my previous car when I changed (93 Concorde) and finally got decent mileage afterwards, wondering what the concensus is tho.

Also I will be having my injectors re-flowed in a month or two, so I would think I'd want to reset it then as well; just wait maybe? Thoughts?

don't buy your 02 sensors from subaru. Do a couple searches here, there was a website (I think its oxygensensors.com) and they have a bosch replacement for our units thats $120 less than subaru.

As for ECU? I reset it after I did mine.

Your ECU is always adjusting fuel and timing, among other things, depending on what inputs is has. Resetting the ECU might not be necessary, but it should not negatively affect your gas mileage to do so.
