Pi ver.6(lite) Maths Definitions needed!! HELP!!

[kshnlayne]

Hi Guys,

I have data telemetery software:PI Version (6.15.1.0) Lite.

I Need to find out how to do a math definition so
that a comparison on two diffrent channels can be done to show any errors
of the driver or the diffrent sensors. e.g. throttle vs brakes, rpm vs gear
changes etc. hope this helps thats all the help i can give on this as i
have no idea sorry!!!. Can anyone or can you point me in the direction to what type of math definitions they would carry out!!

Cheers
