How to Fix a Firmware Update Error on v3 Interfaces


Woolich Racing uses communication interfaces like Log Box or USB to allow the Woolich Racing Tuned software to communicate with the ECU.  The interface firmware is sometimes updated to support new models, or correct issues so it is important to update the Interface firmware version from time to time.

The v3 interfaces are recognized by Windows as 2 different devices depending on what position the device switch is placed.

The switch should be moved to the left position to update the Firmware only, otherwise the switch should be in the right position for all other operations including ECU communications, Reading, Writing, Engine Data, Diagnostics, etc.

If you have started a firmware update/reinstallation, and the software gives an error after starting the update, such as one of the following:
  • "This operation could not be completed"
  • "COM Port could not be opened"
  • "Cannot access a disposed object"
  • "Object reference not set to an instance of an object."
This usually means there is a USB issue. Please first try reformatting the micro SD card or replacing the micro SD card. If that does not work then please try resetting the USB Drivers using these steps below:

Please close the Woolich Racing Tuned before completing the next steps:

  1. Open Windows Device Manger (right click Windows Start button)
  2. Click View > Devices by Container (Important!)
  3. With the LogBox unplugged, put the switch in the right-hand side position, and connect it to your PC using the supplied USB cable.
  4. The interface (Log Box or USB) should appear in a Container called Woolich Racing or similar, as shown below:
  5. Wait for it to appear in the list, and click the small dropdown arrow next to it.
  6. Starting at the bottom of that list, right click on each entry, and select Uninstall Device, (tick remove driver software if available in the next window)
  7. Repeat this process to remove all drivers for the Woolich device until it completely disappears from the list.
  8. Unplug the interface from the USB cable, and move the switch to the left-hand side, and connect it back to your PC
  9. Wait for it to appear in the list again, and click the small dropdown arrow next to it.
  10. Starting at the bottom of that list, right click each entry, and select Uninstall Device, (tick remove driver software if available in the next window).
  11. Remove all drivers for the Woolich device until it disappears from the list.
  12. Unplug the interface from the USB cable and plug it back in, wait 20 seconds, and unplug it, and move the switch back to the Right, and reconnect, wait 20 seconds (for drivers to load)
  13. Once complete, start WRT again, and connect the interface with the switch in the right-hand side position.
You should then be able to complete any firmware updates, or connect to the ECU correctly.

If the problem persists, please Open a Support Ticket.
