how do you tell a 1bar from a 2bar or even a 3bar is it just the size or what

"know i feel dumb"

 

Our stock map sensors (honda/acura) can read up to just about 1 bar. (giving the right management)

GM has some map sensors that are capable of reading up to 2/3 bar. How can you tell? find the part # off the GM map sensor and waaaalaa. I'll see if I can find it, I have one sitting in my toolbox.

i hope this helps..

 

do they bolt righ up, or you just use vacuum line and bolt it whereever? and what, do you only need one if you're running over 14.?? lbs of boost?

 

would you need standalone computer to use one? can you just put one on if using afc hack to run more boost?

 

is gm the only company that puts 2/3 bar maps in there cars

 

theres others..BUT they're pricey. gm is one of the few STOCK maps out there. thats why.
