Will the ECU(Hondata S300) adapt if I change from High Impedance to Low Impedance(w/Resistor box)? Or will a tune have to be redone? My old injectors(debating on sending back to FIC to have serviced if changing Impedance wont work without tuning) are FIC 1000cc High Impedance, My new ones are Precision 1000cc Low Impedance(w/Resistor Box).

Thanks.

If your at the same CC you should be fine, but a lot of times different injectors require different dwell settings and opening characteristics.

The ecu won't "adapt". You will need to properly re-scale the injectors, injector dead times and check over the tune with a wideband etc.
