HXF (firmware) Files

This page contains the latest Tech Edge firmware in encrypted HXF file format. Files are copyright © Tech Edge and are free to be downloaded for use on any Tech Edge controller. Incorrect use can damage your display, your controller or the sensors connected to it! Note that HXF stands for HeX file Format, which is a slightly modified form of the Intel HEX file format.

wbUTIL (re-flash software)

The FLASH utility upgrades the code (or flash memory) as well data memory (EEPROM memory). You only need to upgrade when features you need are added, or when fixes are released. Note : Some feature upgrades may require small hardware changes to make them fully operational.

Warning Note : Using the FLASH utility it is possible to swap between firmware for different Bosch LSU sensors and also to an NTK L1H1 sensor. It's almost certain you will also have to change jumper shunt settings for the controller to work properly with that sensor. If you don't then it's possible to destroy the sensor (heater overdriven and burns out), or to have inaccurate Lambda readings.

Note Carefully: When you reflash a controller, make sure other devices are removed. In particular make sure a display is NOT connected. We also recommend you disconnect any wideband oxygen sensors you have connected. Remember that when reflashing, the rescue-reflash operation should only be attempted when normal reflashing is unsuccessful. If normal reflashing is unsuccessful you should first determine why before trying a rescue operation. The most common reason for reflash failure is incorrectly configured COM ports. We suggest you confirm good communication with the device before attempting any reflash.

Download Latest HXF Files (as .zip)

The following table is composed of non-underlined links (eg. 0e62 ) to individual HXF files which are stored as .zip files so your browser doesn't get confused. You can also use your browser's right click and "Save Link/Target As ..." feature. A collection of HXF files for a device is also available (eg. 2B0 48 ). Also shown are Links to the main page for the device (eg. 3An/3En [new window]) and also pop-up image(s) showing the device shunt(s) (eg. J3 ).

Display Note : The procedure for re-flashing displays is slightly different to WBo2 controllers. The display requires a small reflash adaptor as shown at right - part [PROGDSP]. The adaptor is usually supplied with new displays. The reflash procedure for displays is described in detail here.

Remember that a display should be disconnected from its controller when a controller is reflashed otherwise the display's configuration data may become corrupted, and the display will then require reflashing! The display adapter gets power from the white Molex connector (at the side, and connects to a PC via the large DB9 connector (at the front), the display connects to the black RJ45 connector (at the back).

Release Information

xx63 (Wideband, NTK) - Apr. '13 & Sept '17 (EE tables)

Several NTK HXF files have been added including the 2C0B (17 April 2017).
The default linear 9-19 AFR table has been fixed (one "bad" point was the result of a missing comma in a table in a source file). Note that the controller's "ee memory" (or Electrically Erasable data) is the only relevant change in these files, so make sure the code AND ee memory are re-flashed.

xx62d (Wideband) - Jan, Feb. '12

The controller update fixes the reported version number for the 2J9 controller. The 2J2 controller's firmware file now includes the text 2J2 (rather than 2J0). Note that 2J1 (ie. older 2J unit with integrated cable) may use the 2J2 firmware. Fixed the 2Y1 filename in this document (29 Feb '12).

Note that WButil should be updated to automatically recognise newer controllers (like the 2J9).

xx62 (Wideband) & 0139 (LD02B Display) - Sept. '10

The controller update is for various LSU 4.9 support (rev xx62 additions) and new/extra controllers:

2C0B for LSU 4.2 and LSU 4.9 sopport.
2J2/9 adds the 2J9 with LSU 4.9 support (2J1 and 2J2 LSU 4.2 remains the same).
2Y (DIY) adds support for the LSU 4.9

The display update is for the LD02B. The LD02B adds four rectangular LEDs to indicate the current view

xx62 (Wideband) & xx38 (Displays) - Feb. '08

A release of updated firmware for newer Tech Edge controllers and displays. This release updates the available firmware to bring it in line with recently shipped units.

minor bug fixes and adjustments to logging and user interface.
Support has been added for LSU 4.9 on 2D0/2D1 models - this requires a small hardware change.

xx61 (LSU 4.9) & xx36 (Displays) - Feb '07

Some of our newer wideband controllers (3A/3E, 3B1, 3H1) now support the LSU 4.9 sensor which is quite different operationally to the LSU 4.0 and 4.2 sensors. Other new controllers (2J1), and existing controllers that we didn't have NTK firmware for (2A1), are also represented in this release. Full support for the LSU 4.9 and better support for the UEGO (NTK) sensor has forced us to update the display firmware as well.

0A08 (LSU 2A1) - 07 Dec '05

This release fixes the button press operation and other small bugs and should be applied ASAP. Note that you must use the new version (2.0 or greater) of the flash download utility for 2A1 support. Note also that the HXF file has a header dated October 13 '05 but the HXF file was made available on December 07 '05.

xx49 (NTK various) - 31 Aug '05

This applies to 2E0 and all models that support the NTK (aka UEGO) sensor. Support has been added for 2C0 & 2E0 we did not previously have an HXF file for. Note that we don't intend adding NTK support for 2D models.

xx48 (LSU various) - 14 Aug '05

We suggest you update your current firmware if you've ever seen your WBo2's red LED flash OFF sharply outside of the warmup period. This warning is also duplicated on the right decimal point (flashing ON) of LA1 and LD02 displays. The 48 release adds:

Single OFF (heater PID) and double OFF (wideband PID) flashing red LED to indicate PID unlock conditions. Note that for 2E0, LA1 & LD02 the right most decimal point acts the same way, but flashes ON.
more robust PID parameters for 2B0, 2C0, 2D0 & 2E0 units. This release solves some problems a very few people had with some vehicle installations.

Note: a new release of LA1 and LD02 firmware (available mid August '05) will duplicate this single/double flashing behaviour onto the display's right most decimal point.
