Altitude sensor\ Knock sensor (4000s 1.8l 86)

     Greetings from snowy Colorado,
     
     Just had our first snow of the season here in Boulder and my 
     neighborhood looks like a war zone with fallen trees and crushed cars. 
     Luckily the snow gods shined on me and crushed a BMW and a Toyota 
     truck across the street from where I was parked! I guess my heap 
     wasn't good enough for them ! Well looking through the Bently manual 
     it's not  clear on the operation of the Altitude sensor and living at 
     6000ft I wonder if I have one or need one as it says it's an option. 
     
     My car pings a bit when changing gears and that also leads me to 
     another question, what's up with the dam knock sensor ! The car is 
     originally from the East so I guess it's spent most of its life at a 
     lower altitude.
     
     Anyway keep up the good work and thanks for the entertaining posts. 
     I'm still at the getting stage at present but I hope to  report back 
     on my new Yokos U+4's in a week or two and see how there doing in the 
     Colorado snow. I wish I had a quattro Sigh! 
     
     
     Regards,
