Td5 ECU Tools: scripts for the USBBDM NT

I've been using the USBBDM NT interface to recover bricked Td5 ECU's and modify VIN information. As supplied the USBBDM NT lacks the required configuration to work with the Td5 ECU, so I have written a package of config files and a script that largely automates the recovery process.

I made a short tutorial video a couple of weeks ago that demonstrates how the "Td5 ECU Tools" config/script package can be used for recovering a "bricked" ECU or loading unencrypted map files.

The main menu of the revised script now looks like this:

The interface and scripts can be used for loading any unencrypted .map file or binary image. This means the system can be used for uploading remaps from vendors who supply maps in the standard Nanocom format.

For a working setup you'll need:

  •'s USBBDM NT available here
  • USBJTAG software license (needed for Mac or Linux only) available here
  • DC Power supply (in the range of 12-16V - 13.8V is perfect. I use one of these) or plugged into the vehicle harness for "ghetto style" operations
  • 10 pin dual in line header (for soldering a permanent header to the ECU board) or
    • 2 x IDC 10pin dual inline headers
    • 15cm of 10 wire ribbon cable
    • 10 pogo pins

The script package is available for $50.00USD, which helps to support further work on reverse engineering the Td5 ECU firmware.
Site donors can get the scripts for $25.00USD.

The package has been updated to include an archive of all the .map files available in the Nanocom Map Wizard. These have been spilt into Variant and Map .bin files. I've also put together a reference pdf listing all known factory variant and fuel maps.

Please use this  contact form if you are interested in purchasing.

Please do not order unless you have the interface in your possession. A few people have had trouble ordering from so you need to make sure the interface arrives before buying the scripts. I can get the scripts sent out within 12 hours of receiving payment.
