Thanks for the replies everyone, I made the changes and its behaving correctly now. I have the main VE basically finished and will start on the boostVE. I am going to autoVE the boost ve table but was wondering what happens with the commanded afr over 105kpa? I am looking for an afr of 11.5:1 at 12psi but as the commanded afr at 105kpa is 12.8:1 must I fudge this ritchening factor using the boost VE table? If so this will affect the BEN factor during autoVE wont it? Just not too sure how you all do it. Any info will be greatly appreciated.
