Reflashing a COMPUSHIFT Sport or COMPUSHIFT Pro
Precautions
Reflashing a controller is generally a safe operation, but it is possible for the flash to fail and leave you with a vehicle that won’t drive. Do not attempt a reflash unless you are prepared for that possibility.
Software updates are usually downloaded over the internet, so the device you are using to reflash the COMPUSHIFT must be connected to the internet.
If for some reason the reflash fails, the COMPUSHIFT will force you to retry again. You will get a message in the setup app telling you that the “Bootloader” is active. The bootloader is the software on the controller that actually performs the reflash operation. It is separate and distinct from the software that controls a transmission. When the controller is running the bootloader, normal transmission control is not possible. Only after a successful flash operation will the transmission control system operate normally again.
Recovery with the A-B Mode Switch
Grounding the A-B mode switch when the COMPUSHIFT is powered on will force the controller into the bootloader and will also enable Bluetooth. This is useful if Bluetooth has been disabled or faulty software has been loaded for some reason.
Be sure not to inadvertently ground the mode switch input by leaving it disconnected in the vehicle. The wire should be either connected to a pushbutton switch or taped off.

Reflashing via Bluetooth Using a Mobile Device
Here are brief instructions on how to reflash a COMPUSHIFT Sport or COMPUSHIFT Pro via Bluetooth.
Before you do anything else, be sure that your mobile device has a good charge or is connected to power. Your device will need to be connected to the internet.
If you haven’t already done so, go to the app store for your device and download the COMPUSHIFT Setup application.
Place your device within 6 feet of the COMPUSHIFT controller and turn on your ignition key to power on the controller, but do not start the engine.
Start the COMPUSHIFT Setup application. Your COMPUSHIFT controller should appear in the list of devices, and may connect automatically if you have used it before. If not, select your device to connect to it.
Press the menu bar on the upper left and select “Firmware Update”.
When prompted, agree to the update process. It should take about 6-8 minutes to reflash, and there will be a progress bar that will update during the process.
The setup software will display a message when the reflash is completed.
You can then reconnect to the COMPUSHIFT when the flash operation has completed.
