Thought I was going to have to hook up the bench harness , but decided to uncheck the high speed transfer box and try again.
This time started uploading imediatly and all done in 3 mins.
Any reason for this happening ?
Haven't tryed flashing my own car yet - it is a problem car to flash with Edit via the OBDII port - killed 2 PCMs and only tryed twice :evil: so always have to use bench harness which is a PITA.
cheers
