    '07 CTS with E55 will not write

    Will read ok, will initialize and erase and that is where it stops and says failed. Leaving the door open, radio off and no help. Any ideas ? Thanks !

    Is the file you are trying to write a modified version of the calibration file you read from the CTS? (read, modify, write the modified file?)

    Also this thread is relevant -- write problems suggest cable or connection issues. https://forum.hptuners.com/showthrea...-Write-Failure
