Trog, it's interesting you mention Auto-VE feature. I just finished reading a book "How to Tune and Modify Engine Management Systems" and it states that the very first thing to get setup properly is the VE table. It even goes on to explain that systems with Auto-Tune feature for VE-table should set the target AFR to 12.8 across the board, this way you will always be rich enough even for hi-load conditions. Then with 12.8 as the target (for every RPM/Load combo) simply enable auto-VE and let the system build the VE-Table. Then you will fill in VE cells that are hard to reach or where not obtained by hand. The basic idea is to shoot for a safe rich mixture that will work under most all conditions (12.5 to 12.8) then let auto tune go to work and tune/build the VE table for you. Once the VE-table is built you simply pull fuel out via the fuel trim table for the lighter load areas.

After the VE is built then proceed to other tuning, like starting to tune no-load/lo-load for 14.5AFR and things like this. Also Acceleration enrich should also be done only after the VE table is correctly tuned. The book states to tune the VE-Table first and only when the VE-table is correct should you move to other tuning.
