I can understand why people might recoil at the thought of using wasted spark or semi sequential injection on a car that had "direct fire" and "fully sequential injection" in the OEM ECU. It does seem like a step backwards, however its been shown that this ECU is capable of producing 500 hp/torque in a lightly modified stock turbo Z32. At these power levels "wasted spark" and "semi sequential" injection is obviously not a performance limitation. At higher power levels it may be.
