Reset/reflash ECU when aftermarket airfilter and modded exhaust?

  1. I installed a K+N airfilter and also have modified the stock exhaust with some small holes drilled in the back.

    CBR250 which I believe runs a closed loop from ECU and O2 sensor.

    Should the ECU be reflashed by disconnecting the battery by 5 minutes to maximize (small) changes in the breathing system?
  2. ^ Thanks. Interesting. I remember seeing that years ago and had forgotten all about it. Something I'll have to read up on. :) I didn't know that's what it does.
