A/F reading, help a newb
So my new 496 had got 80 miles on it.
The smell from the exhaust has always smelled way rich to me.
I had Lars dial in my QF 830 and he showed me a picture of 14.2 after setting it up.
Today I bought a Innovate Motorsports 3837 LM-2 and hooked it up to the tail pipe. They warn you that you can get false lean readings.
Would you expect 80.1 to 40.1 at idle?

The tail pipe probe is pretty useless at idle, I'm told.
