You shouldn't need to mess with the ECU, but the wiring where the harness meets the ECU needs to be cut and re-spliced to the switched 12v instead of the constant. This should be done regardless of injectors. The new injectors seem to hold up against ethanol better. The guide in the FAQ section is quite comprehensive.
