Hi Valleyfred.  Your description of what you are trying to do is a bit brief but I think what you want is "Closed Loop Lambda" or CLL for short.  With a wideband sensor you can do two different types of CLL.  

1), Stoich mode, this is traditional CLL like an OEM ECU where the Lambda is controlled to cycle or "dither" slightly either side of 1.00 

2), Auto mode, this is where you use a target lambda table and the ECU tries to trim the fuel to match that target.  Some of the basic settings for automode is shown below.
