Trailblazer SS, 2006, E40. How to shut off one 02 sensor?

[Praxis]

Normally there is a injector bank assignment in other ecu's, cant find it (turbo charged, single 02)

Thanks

Do you want to disable the front NBO2 on one bank...?

You could unplug the harness from it.

Yes. I want to have closed loop still functional, but only correcting both banks from bank 2 front sensor.

Plus if I am not mistaken, the ECM associates the cylinder timing with the O2 signal timing. But then I could be mistaken ;).
