I'm quite sure both of the tables values are going down, but it's adding fuel, I have two wide bands, one is in the exhaust and hooked to the scanner, the other is on the dyno and they both read the same air fuel ratio, so I confirm that I'm not getting garbage data from my wide band
It's almost as if there is another table like a secondary VE table that I cannot see in the tune, but is looking up that table when I go into PE mode
