Update firmware

The Power Commander V, SFM, and PCV Ignition module all take the same version of firmware, and all modules on one vehicle need to have the same version. The Power Commander III USB and Ignition module have different versions of firmware available, and they need to have compatible versions. If you update your Ignition module, you may also need to update your Power Commander. Be sure you select the correct firmware for your device. The Power Commander III USB needs the 9 volt adapter to do a firmware update. The Ignition module needs the Programmer module and 9 volt adapter. The latest firmware is freely available on our webpage.
