This is the multiplier of the fuel determined by the LTT algorithm to hit the target AFR.


Essentially, if you have a cell in your VE table set to '50', and the LTT Trim table has determined that same sell to need a trim of 1.1, then in reality, you should set the VE cell to 55 (and then reset the LTT trim to 1). YOu can of course use the LTT Wizard to do this.


A 1 in any cell means the VE is not adjusted.
