I understand what you are saying, but I want vacuum delivery.
What I was meaning was to move my threshold point a little lower and my max a little higher.

EG:
Threshold at 15"Hg/2=-7.5psi. -15+-7.5= -7.5Psi. -7.5psi x .1666= 1.25V
Max at 7psi. 7psi = -15psi + 22psi. 22 x 0.1666 = 3.66V.
This gives me about 2.4V to play with.

I can probably go as low as 20"Hg and as high as 9psi which increases it all a little more
The biggest problem is that i dont make a lot of boost so really no matter how we span the 5Volts the "progression will be quite rapid.
By injecting in vacuum I can at least extend the span a little more.

Do the other trimpots have thier usual adjustment functions?
EG: Does IDC Trim set at 50% still match Threshold value given it is now Volts and not IDC?
