Default Supercharger ECU and Injector question

I recently tried swapping my ECU with the supercharger ECU, it is of the same year and transmission but the vehicle would attempt to start for a split second then die, after that it would only crank. Im thinking maybe the engine is not getting enough fuel so I did buy 440cc injectors that said they would fit the tC but the wiring is an EV1, im not all that great at soldering so does anyone know if there is a adapter to let me use my injectors.

Did you re-program the key to the new ECU? If I remember correctly the tC has a transmitter in the key that is coded to the ECU.

I don't know why you're using the AFM for a supercharger. The ECU utilizes injector length, not wind current, for the adjustment.

What injectors would you say you are utilizing? You need to guarantee the injector dead occasions are right and set the injector stream for efficiency boundary.

That makes zero sense. On input side, ECU need to measure in-coming air-flow/volume. This is done with AFM, MAF or MAP sensor. Using that incoming data, ECU then calculates output injector pulse-width (duty-cycle).
