The Delphi ECM is continually updating live anytime the motor is running. There are however some early EFI vehicles that calculated Baro before the motor was started which could potentially cause issues if you experienced large changes for example in altitude or air density, fortunately this is not an issue with the Delphi EFI used on HD models.
