Has anybody tried this switch yet? Just wondering if it works well.

Re: A/F Safety Switch (shftn6)
Wow, they sure do make a lot of general statements with regards to trusting the OEM O2 "narrow band" sensors FIRST, and then the corresponding voltages SECOND. Oh my.
WA 2 many variables for each different motor to trust generalities like that.
You guys who run 13.2:1 A/F ratio on the juice...have fun picking up the pieces of your motor unless you're running 116 octane.
And beside that, EVERY OEM oxygen sensor produced is designed to be accurate right above and below 14.7:1. They are not designed to be accurate beyond this very narrow range. They don't need to be. So trusting the voltages as "gospel truth" for your A/F readings is rolling the dice...and when the margin for error in a forced induction application is much less than with a N/A engine setup, this is a big risk.
