The ECM converts 5 volts to an 8 bit value.
5 / 255 will give you Volts reading.

Create additional items or change the existing conversion formula.

Not sure i understand the whole equation thing.Could you expand a little bit on the subject for a newb? It has been a heck of a learning curve for me so far.I greatly appreciate it! Talking to me as if im a child might help Im just an old child!

For the conversion use:

(5 / 255) * X + 0.000000

or, reduced:

0.019608 * X + 0.000000
