Hey guys,
Im tryin to figure something out...
What is the AFR suppose to be while at idle???
Ive got No cats, STS, and my WB O2 is about 18" after the Turbo.
And this is a screen shot of my Idling... attached is the Log.. (Used EFI Live)
You can see at the top of the screen in blue, Value=15.94
Min=14.42 Avg=15.62 Max=16.46....
Commanded is 14.68....... what gives?

Thanks guys!!!!!

First go to the PID you use for logging and get rid of one parameter to get the channels down to 24. At 25 channels you are only getting 5 frames of data per second instead of 10.
Then go to your VE table and cut 10% of your fuel at 800 rpm all the way across and see what affect that has.
