The FIC does not have injector offset calibration, so you will not need this. In addition, the FIC has its own onboard MAP sensor, so the 3 BAR sensor you have is not needed.
You may wish to consider using a stand alone engine management system (we offer a Series 2 EMS system for your NSX) with that large of an injector with modified camshafts. Especially if camshaft angle is changed from intake to exhaust, the FIC will not be able to handle this.
If you have any questions or need help, you can always drop us a line.
