2018 Mustang stock calibration number for IDS

Have an 18 that we?re trying to return to stock updated to Fords latest software but are hitting a brick wall. IDS won?t connect to the PCM because it?s flashed. Put in the VIN and says not recognized and asks for more info. PCM part number, tear tag and calibration. This is a Bosch PCM and I don?t see a typical calibration code like the Continental PCMs have. Any idea where I can get the calibration info? Tried to see if Forscan listed but also can?t connect due to not stock calibration. I have the part number and tear tag info but no clue on where to get calibration number.

All you need is tear tag for IDS to work. If you have that, then you should have no problem getting into the pcm with IDS/FDRS (IDS for 2018)
