Tony, if the atmospheric conditions are changing while you are going down track enough to affect performance, those conditions are to blame for you missing your dial in, not your EFI system. There is nothing an ECU can do to offset those changes, it can only provide the correct amount of fuel to maintain a consistent Air/Fuel ratio so that the change in performance is proportional to the change in air. In reality, it is doubtful that the air can change enough in the 9-10 seconds to cause you to miss your dial in.
