no it's on the open loop closed loop transition. Your tuner isn't going to be able to see it unless they have a dyno that they can put a load on to simulate low rpm stress on the motor like driving slightly up hill in 6th gear at 65mph. you probably had it in 6th gear on cruise control and started going slightly uphill the first time you noticed it.
Did the problem go away briefly when you reset the ecu?
