and there it is, thanks Heath. 
2 bar volts psi range (for logging boost)
2 bar volts psi range (for logging boost) I'm putting a 2bar Cobalt sensor on my setup. I'd like to tap the output and feed it to my E-I-E-I-O 
on my hptuners/vcmsuite for logging boost relative to airflow, timing, kr, etc.
Anybody have the voltage range and mapping to boost pressure so I can set up the input properly?

[QUOTE=frcefed98]Heath, how would you tap the MAP sensor to read boost? Sounds like a cool idea and would really help see where i'm at on the log.
you tap into the green wire and run a wire into the car to input into the eio cable
then setup a user defined pid for boost that looks like this.
name boost
abbr boost
sensor manifold absoulute pressure
units psi
click on list
paste this in.

viola your all setup.
just add it to your table and charts and your good to go. it's way cool to have and it dead on accurate

it could be used to log voltage, and then a external program could be used to convert the data... OR.... you would need to figure out a formula.. there is no lookup table (to my knowledge) that can be used for user defined PIDs outside of the EIO
but afterall... thats what the EIO is for.

Especially if (when) I upgrade to the 2-bar version for my '98.
