What module are you trying to program

PCM usted with 908p

  Depending on model year and whether or not you still have the original PCM that is still capable of communicating with the MS908P you might have the option to install a used salvage yard PCM of the same # from the same model vehicle into your car where it will pull some fields of information off the old PCM,  then you'll be instructed to install the replacement, which the MS908P will overwrite some of the original files on, however reprogramming an existing PCM or a new blank replacement Hyundai PCM  to latest calibration level cannot be done from off the MS908P tablet. Only some BMW , and Mercedes Benz during active update period.
