     A lot (if not most) aftermarket systems are MAP based because its 
     easier to deal with.  A MAP sensor, a water temp sensor, an air temp 
     sensor, a tacho signal and a TPS sensor, and you are off and running.

     There was a discussion a while back about aftermarket systems, and 
     someone compiled a table of the various systems and their features.  
     Could who ever did this, mabye post it again ?
     
     
     
Can you get my more information about a MAP based system?
     
(I have look at it. Differential pressure measurment over the butterfly and 
temparatur compensation and maybe huminity correction and so on...)
     
Is there a manufacturer for this device (body and butterfly)?
     
Thanks

P.S. Processing power is cheaper than engine power....
