And the existing software code provides a redundant safety feature that provides two-fault tolerance. In the event that the relief valve should fail (not an unheard-of occurrence), the software limits the pressure output of the compressor to a safe level well below the burst pressure ratings of any of the pneumatic components provided in the FIRST kit. For that reason, the existing software that turns the compressor "Off" at 120psi must always take priority over all other functions.

(and yes, it also works the other way around - the relief valve acts as a backup for the software, in case you accidentally do something to mess with the software-commanded shut off)
