Sound like a bad WB02. Driving me crazy

Since installing new LS2 TB and ported FAST90, my tune has gone crazy.

I do a BEN Map and it calls for more fuel as an example an average cell value of 1.06. I make the adjustments, do another BEN Map and results are similar calling for similar additions to VE table. Right now my idle cell in VE Table is over 70 and table almost looks flat on top.

If i go out run car in OL, WB02 is within one point of CFOL but never gets an closer. If car idles, wb02 goes lean to tune of about 19:1.

Any comments/suggestions?

FWIW, WB02 is new but I did have trouble getting it to click.

crazy lean/rich spikes are a sign of a bad wideband sensor.

Come to Warren's on SAT and you can use my WB and EFI to eliminate that possibility.

Sounds like fun. I'm afraid I might buy something. :)
