I get a leaner reading from my Aero Force. I would think that the tailpipe sensor would be leaner, considering that the spent fuel has gone thru the cats. :icon_confused:

I have calibrated it about 2 months prior to dyno.

Has the Aeroforce been calibrated lately?
And viewing my logs thru DataViewer they have remained consistant prior to the calibration at dyno and beyound. Just do not understand why dyno is richer and at a better level than when I just get on it in second gear to get a log. Maybe it's the rolling throttle at dyno compared to the fast WOT I do when logging.

Got sensor before the cat.

A/F gauge sensor should be installed before the cat and that will give you the most accurate reading.
That is where it is.

Reading is leaner.

Hoe much a difference? Normally the A/F will be .1-.3 leaner after the cats....
Leaner about .2-.4 on my gauges, on my sensor which is before the cat and the tailpipe reading is richer by this amount. Also the graph from the tailpipe is smoother.
