Wide Band Help, please

I have installed AEM uego yeserday, and noticed that at cruizing speeds it is reading 15.4 or so the only time it reads lean is at WOT is this normal or what? Also when coasting it reads --- or 16's, WTF. oh and when sitting idle it fluctuates between 14.2-14.7, any help would be aprieciated

Lean is higher numbers... Youve got them mixed up.

Cruising, low throttle 16:1 is ok... I idle at about 15-15.5:1 and cruise aroun 15.5:1

The biggest variables are:

Where is your sensor located?

What setting is you AEM uego set to?

OK the bung is at the flex pipe, and I still have it at P0 setting. and I put the wrong word I meant rich so all I wrote is the same except that word. I did notice if I am at WOT or near it It is running rich like 11.x or so. when tuning my SAFC2 shiould I be at WOT or does it matter on how much throttle is being used? I am rather concernd like I said when I let off the gas to coast it will lean out past 18 and I hope it is normal.

Going lean under coasting if normal.

Set the SAFC2 "hi" throttle table to 80% (that is where the stock PCM goes into open loop mode). The just tune the high tabe. The PCM will adjust to the settings you make at low throttle to try and brign the fuel back up or back down so that it can achieve 14.7, so adjustment al low throttl is basicly pointless..well, if you hvae cams, then that's another animal...but lets start with one thing at a time.

coasting is ok. it should read full lean on decel.

OK that is what is happening. So when I adjust the 12 points they will only work (theoreticaly) on Hi throttle, if setup correctly? After driving my car for 2 days with the WB I am finally starting to get the hang of its constant movements, and all my cars little quirks (like a rev limiter in neutral or clutch disengaged), lol.
