SERT Displacement Setting
 

Just curious.. Was looking at my SERT MAP and had noticed that the Displacement Setting&nbsp\\; under the constant settings in the MAP is set to 110.3&nbsp\\;&nbsp\\; When in fact I'm running a high compression 10.5:1 103 CI -&nbsp\\;
&nbsp\\;
Does this effect the fuel delivery ?&nbsp\\;&nbsp\\;&nbsp\\;&nbsp\\; I believe I may be running a bit rich is the reason I ask.
&nbsp\\;
thanks

Changing the CI number in the constants will effect the VE tables. Your tuner may have bumped up the Cubic Inch number because he was reaching the upper limit of the VE cells he was trying to add to. In effect, the bigger the Cubic Inch setting, the higher the VE tables can be set.

Be very Careful with just changing the CI. Your present tune, afr's, &nbsp\\;will completely change and you will not know where the burn is unless you get it tuned again. The only reason you really need to worry about the CI is like I said above, you ran out of room for bigger
ve numbers.
