Hi again.

I'm looking at this chematics from this link: http://www.msgpio.com/manuals/gpi.htm, for Voltage sensitive input.
Is the resistor Ra and capasitor Ca/Cb included in the kit? I cannot find the values either.

I'm only looking to get more analog inputs for fuel press, oil press, back pressure etc.. In the log, and EGT's are also a nice thing to keep track of.
I don't need megashift or dbw or other advanced stuff I just want some extra inputs and outputs.

Are all the features listed on this page:
http://www.msgpio.com/manuals/
standard features if the GPIO board? Or is it just optional circuits?
