More silly ideas-MAP2

second MAP.>>


If one were to drill a hole in the chamber on the backside, 
opening the MAP up to atmosphere, isn't that the same as 
reading a separate MAP for BAR and doing the subtraction? If so, that seems
like the cheapest yet still accurate 
way of reading true MAP, since it would already be corrected 
for atmospheric pressure. 

I think I have a spare MAP lying around, I guess I'll 
have to open it up take a look. 8-)
