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.
Can anyone guide me on bolt on turbos.. I have a final project coming up.. I've been thinking to turbocharge my stock proton 1.3 injection.. Just trying to get a light boost.. 0.3 bar is good enuff.. Just making sure...
