I was under the impression you tune the entire maf curve for stoich initially. Leave the base fuel table at lamba for all of the low load and low throttle position. Adjust the maf transfer function in open loop until its darn near 14.7 under all part throttle driving and project the trend to conditions you can't datalog at cruise. Then adjust base fuel table high load/ high throttle position to what you want at WOT then readjust the maf transfer until you see your commanded lamba. I guess you could just leave it all at lamba and just continually ramp up the maf but then the system is less adaptive/dynamic.
