You need full DCS- a TIU or the new upcoming WTIU.
The DCS commander is limited, the firmware is old and not supported or updated to even the same version as the TIU.
Again, the DCS Commander was last updated 2011, at only version 1.4, where as a TIU version is 6.10- so yes, that many versions and lack of updates- thus features were never really added to the Commander VS the TIU.
also the manual for the commander- no way to edit setting in the engine like chuff rate.
