Sell the AFC if you already bought it and go DSMLink. Much better to tune with and use. Otherwise, your simply guessing what your doing and its a hit or miss situation. My opinion. But if your running the AFC, some basic settings
http://roadraceengineering.com/newafcsetting.htm You can find a car that fits what you have and get a descent start on somthing to work with. On my car, it worked alright til I bought dsmlink, then I dropped about 1 sec in the 1/4. But, that was without and dyno time. You should be able to get a little bit better with a wideband and some time on the dyno.
