## Firmware Update
|
|
|
|
rusEFI own wideband module requires one time initial programming. Self contained version of the board relies on custom USB header while module integrated into Hellen requires usage of ST-Link programmer hardware via TC2030 or breakout SWD pins.

|
initial programming binary at https://github.com/mck1117/wideband/tree/master/for_rusefi
|
|
|
|
At the moment only known to work using stm32cube software not ST Link utility (weird). In case of Hellen 5v via USB is required.
