Ok boys, who remembers their math?
I've been trying to sort out my analog equation for my AEM digital boost gauge.
What I have been looking at is this:

The gauge swings from -30 to +35 and is a 0 to +5v analog output. That's a swing of 65 points over 5 volts
This is the formula: (v*13)-32.0 Problem is, its wrong.
It works at 21 lbs vacuum just fine (-21)
At 10 lbs boost, the equation gives a result of -1.4 obviously, I should get +10
Now, how do I figure this out using the above info, rather than trying to use a voltmeter and creating boost/checking each voltage?
