I would rather have it a "Sensor Error" on my screen than a 11.0 A/F reading when it's really 12.0.

I like to use the NTK sensors instead, they cost a bit more though, but they do last a lot longer, especially if you ever run race gas.

I never knew that about the plx units I might have to think of switching to a different one
