You have essencially 3 different WOT range fueling modifiers that have direct affect on your AFR at all times: PE Enrichment (EQ Ratio vs RPM) table, VE table (at the 95, 100, 105 kpa ranges) and OFLA table (at the same ranges as the VE table). More on that but first- You will also know ur in PE if your TPS% and MAP satisfies the PE Enabled HOT/COLD tables, alas you will be in cell 22/OL (cell 22 = WOT, cell 21 is Idle/throttle closed, Cell 20 is decel, right? I might have a couple of these switched up, been a while
). If you still seem to be getting stoich AFRs when in WOT 100% TPS, try setting the other PE Enable parameters to 0 value (the MAP, MAP Hysteresis, Delay, Enable Torque, Torque hysteresis). At any rate, you can certainly tune your WOT/PE parameters utilizing the VE table, the numbers >95kpa MAP + your WOT RPM range you wish to tune will affect your AFR per your WB. I dont try to Paste Add/Subtract/Special the %err from the histogram scans to tune WOT AFR, I simply look at my WB scan recording results in the cells 95, 100, 105kpa (or more if you have 1 bar HPT + forced air) readings throughout the RPM range that I am tuning for my 12.8:1- 13.0:1 AFR for naturally aspirated WOT AFR. I make changes in those cells accordingly in my VE table in those cells. Leave the OLFA cells at 1.001 in all the wot range as well as your PE Enrichment table to 1.001 then simply tune your WOT AFR using the 95,100 and 105 kpa cells in the
VE table. Using the VE table to tune your WOT as well as Closed Loop part throttle SD tuning gives you a little more resolution to tune WOT AFR because instead of a single cell per RPM column to tune WOT (as you only get in the PE Enrichment table) you get 2-3 cells per RPM column to tune naturally apsirated WOT in the VE (95kpa, 100kpa, 105kpa cells per each RPM column can affect your WOT AFR). Remember to leave your OFLA at 1.001 in the WOT range and leave the PE Enrichment table alone, as well, at 1.001 as these are WOT modifiers at all times.
