rusEFI Bundle¶
The rusefi.bin file is compiled rusEFI firmware. Sometimes you would have a rusefi_no_asserts.bin variation of this file with fewer safety checks.
rusefi.dfu is also compiled rusEFI firmware, which is used for the DFU mode of flashing.
rusefi.ini is the TunerStudio definition file, which you would use if you use TunerStudio software to tune your rusEFI ECU.
