    Hi Marc
    Good to hear back from you. How much does your AFR oscilate? Where is the wideband located? Depending on position, you need to adjust Lambda rate and Gain. 
    You should do some testing. Tune your VE table with CLL off  as good to your Target AFR as possible. Adjust your target AFR table to the rich side with one task by the amounts listed in the gain table 0,33 0,66 etc. And log, with a high logging rate, how long the sensor needs to get to a stable reading. 
    Lets say it needs 0.3 seconds. This means your frequency in the lambda rate table may be max. 1/0,3  = 3.333
    This test should be done at different loads and rpms to work out best CLL settings. Best place to do that is a load bearing dyno.
