i think that adx is broken.

it takes a linked value from MAP KPA, then applies this formula: 29.9-(X*.349)

that isn't a good conversion afaik. think about it for a sec, 100kpa (which should be atmospheric pressure, WOT, no vacuum, should be 0 inches of mercury)

that'd be 29.9-(100*.349) = 29.9-34.9 = -5

derp?

kpa to in/hg should be 0.295

i do suck at math but i think you should go with 30-(X*0.295)
