FAST b2b O2 calibration question.

[UR50SLO]

Just about ready to fire up the car. I have a base tune from another fellow buick guy with a similar build. Just wondering if I need anything special to calibrate the widband that came with the ECM?

I remember getting a calibration file with a O2 sensor when ours came in broke.

Anyway I can verify that it's reading correct?

Thanks,
Scott~
