if all you get is o2 voltage, air temp, coolant temp, timing advance, RPM. vehicle speed, TPS. that may give a basic tuning for like boltons but with a turbo you'll need to tune in injector pulses in order to idle good and have a wider pulse on the throttle, also vacum/boost to advance or retard the ignition, and the basic o2 reading wont help when a wideband should be used to tune with. it may be a half ass hack that works for cheap but you get what you pay for. piggybacks under boost........BOOM
