Directions
- Download the file to your laptop.
- Connect the serial cable from your laptop to the WOT Box. (or use a desktop if you can get one close enough to the car).
- If
you do not have a serial port on your laptop, you may need to purchase
a USB-to-Serial converter. You can find an inexpensive one here. If you have lost or damaged your serial cable, you can find a replacement here.
- Key on the car. The car does not need to be running for the firmware upgrade to complete.
- Start the upgrade program. It will go through a few screens, including one that will require you to fill in the COM port number of the port you will be using. You may need to look this up in the device manager to find this out.
- Run the flash, it should take about 5-10 seconds to download and it will pop up a message when complete.
Firmware Version 2.3 - 7/9/08

- 2-Step minimum RPM is now 2000. Please use the following table to program the 2-step RPM after the update.
2-Step RPM Chart - Set with the clutch DOWN
| Blinks | RPM | Blinks | RPM | Blinks | RPM | Blinks | RPM |
| 0 | Disabled | 6 | 3000 | 12 | 4200 | 18 | 5400 |
| 1 | 2000 | 7 | 3200 | 13 | 4400 | 19 | 5600 |
| 2 | 2200 | 8 | 3400 | 14 | 4600 | 20 | 5800 |
| 3 | 2400 | 9 | 3600 | 15 | 4800 | 21 | 6000 |
| 4 | 2600 | 10 | 3800 | 16 | 5000 | 22 | 6200 |
| 5 | 2800 | 11 | 4000 (default) | 17 | 5200 | 23 | 6400 |
- A 2-Step lockout was added that now requires the engine to be below 1500 RPM before engaging the 2-Step. This prevents the 2-Step from inadvertently activating on the highway during an aggressive shift.
- The maximum cut time for the auto WOT Shift feature was reduced from 600 ms to 350 ms due to concerns about check engine codes being tripped after a missed WOT Shift. This change should not affect normal WOT Shifting.
- 2-Step only WOT Boxes will now be able to complete the troubleshooting
procedure steps 2-4. The LED will cut during a WOT Shift, but the
ignition will not be cut. Therefore, troubleshooting step 5 will still
not work.
