Buick Regal, T-Type, Turbo T, Limited, Grand National, GNX
SENSOR NAME:
wideband oxygen sensor
PURPOSE OF SENSOR:
gives a better reading for tuning than the factory O2 sensor does
TURNS ON-OFF / FUNCTIONS / USED WHEN:
in constant use while the engine is running
LOCATION IN VEHICLE:
in the downpipe, after the turbo.
at least 12″ (sometimes 24″) away from the turbo.

THINGS TO KNOW ABOUT THIS ITEM:
the sensor itself usually runs to a “controller” for it, then gets connected elsewhere (powerlogger, computer, etc.)
some chips (like turbotweak, as an example) can use the info from the wideband sensor to run the engine
OTHER NOTES:
we used an AEM wideband, but there’s many other systems out there (PLX, Innovate, etc)
[see our own wideband installation here, along with photos and how to]
