H&S *Must be accessed from a Windows based computer*

It is highly recommended to have your truck on a battery charger while attempting a download. Also, any aftermarket accessories should be turned off/unplugged.

*If you have a 2007.5-2010 Duramax that experiences a 312 error code while installing, please give us a call. You will need to have the device and the truck together for us to resolve the issue.
*If you have a 20011-2014 Ford and experience an “Unrecognized Part Number” while installing, please follow the steps below to resolve the issue.​

BC20xxx = 2011 ECM
BC33xxx = 2011 TCM
CC20xxx = 2012 ECM
CC33xxx = 2012 TCM
DC20xxx = 2013 ECM
DC33xxx = 2013 TCM
EC20xxx = 2014 ECM
EC20xxx = 2014 TCM

  1. Write down the exact error that the H&S product gives you. It will look something like
  2. Remove the SD card from your H&S product and insert it into a computer.
  3. For 2011-2012 model year trucks, open the folder "FORD67". For 2013-2014 models open
  4. Reference your error message written down previously and note the first 4 digits of the file name. Your device is telling you that we do not recognize the particular OEM calibration that is on your vehicle. The H&S is simply looking for that exact file name on the SD card, and then tuning will proceed. Match up the first 4 digits of your error message with the first 4 digits of any other file on the SD Card. There will be MULTIPLE files that match the first 4 digits, use ANY of them.
  5. Once you have selected a file that matches on the first 4 digits, make a copy of that file.
  6. Paste that copy into the same directory and rename that copy as the EXACT file name that your H&S gives in the error message. For instance, if my error message stated "Unrecognized part number DC20BMF.MM", I would rename the previously made copy of any "DC20xxx.MM" file as "DC20BMF.MM".
Once the file is correctly named on the SD card, the H&S product will allow you to proceed with
tuning. If you get another error message, your TCM file is likely unrecognized also (BC33xxx,
CC33xxx, DC33xxx, EC33xxx). Proceed with the same steps above to rename a file already on
the SD card to match your error message.
