You can use TuneECU to load maps, edit maps, reset the ECU and preform diagnostic tests and calibrations of various controls and sensors. You really do need to do the 15 minute idle after most of these operations. Otherwise operational data which the ECU retains in flash memory may not be valid for the changes being made. I recommend reading TuneECU thread
