Last time we talked about setting up the MAF map and adjusting it so that the MAF sensor plays nice with the AEM FIC.

The reprocussion of this is that you will pretty much never get an accurate tune (when compared with going full standalone) and a good example of this is fuel adjustment via the MAF and Fuel Map.
