If your F12000R is using the default settings (4 2 0), that could well be your problem MPG wise.
I'm considering either the Cobra or Techlusion units, but one thing about the Fi2000R that struck me as strange was the default settings seem very high, especially the one effecting the cruise state fuel delivery.
If you look at RS900C very helpful post above, he is using the Fi2000R with a setting of (1 1 0) which seems consistent with the settings Techlusions recommend with their unit. A settting of 4 2 0 would be really increasing the pulse width, and the green or left pot ( the one set to 4 ) is the one that controls the fuel delivery while crusing or at constant speed.
Setting your green, yellow and red pot to zero should be effectively the same as removing the Fi2000R without actually physically removing it. I.E., it shouldn't add any additional time/width to the injector pulse.
Since you don't have any intake modifications, the amount of extra fuel required should not be too much if any.
Hopefully some of the people who have been so helpful to me will see this post and comment or correct any information I have given, regardless of how well intended, that is incorrect.
