What causes the coasting portion (25-30 kPa) of the VE table to always be lean according to the BEN Maps. These cells always have the highest cell counts in the Map. You could increase the VE values for these cells to 200% and it would still go lean. (The other lean values in this particular BEN Map are just the result of a smoothing experiment.) DFCO is disabled.
