Programming the BAC controller is done with the ASI BACDoor PC Suite (which can be found here if you look carefully) via. a cheap CP2102 USB-TTL dongle (available on eBay or Amazon).
NOTE: COM port baud-rate is 115200.
The important pins on the 16pin connector for programming as as follows:
| PIN | FUNCTION |
| PIN 3 | TTL-TX |
| PIN 9 | Power / Ignition |
| PIN 13 | TTL-RX |
| PIN 14 | Ground |
NOTE: The ignition pin needs to be connected to the battery positive but be VERY VERY VERY VERY careful that you do not accidently touch another pin because you’ll cook your controller!
