yes, actually any piggyback/aftermarket ecu that can reference turbo can use for NA, because they actually do not need to reference boost for NA in the fuel & ignition mapping.
If the system for NA only, then cannot use for boost.
Software is as cardinal as hardware in squeezing out power from a modern engine these days. Just plug in a laptop, reflash the ECU with a new ignition and fueling...
