However, We would like to inform you that we do not share firmware files/updater and other files in the community forum. Please contact your Sales Manager/Distributor to obtain the firmware files. If you don't have any contacts with our Sales managers, please contact them on our official website

Regarding the connection, it is similar to an immobilizer but DOUT goes to the fuel pump instead. DOUT is used to disable the fuel pump when a threshold is met (as configured).
Thank you for your understanding.
Kind regards.
