MAP sensor question...
Hey guys -
Was wondering if anyone knew if the S65 MAP sensor was a 1.5-bar, 2-bar sensor, etc...
I have a log of data and want to make sure I'm mapping boost right![Smilie](https://mbworld.org/forums/images/smilies/smile.gif)

I am not sure what they are exactly but they have to be at least a 2 bar. Since they run over 20 PSI stock it would be over a 1.5 bar sensor.

Actually its probably a 3 bar sensor. At 0 pressure you have 14.7 psi (atmosphere) so in order to acheive the ability to run 20 psi of boost you actually have 14.7+20=34.7psi of pressure total. So in esence you are close to 2.5 bar already. Confusing I know.
Or even easier;
1bar for vacuum and 2 bars for boost. So on a 3 bar sensor your max readable boost is around 30psi.

Thanks guys...the theory makes sense - was always just easier to figure out in the Supra world. MB specs seem like a secret ![Wink](https://mbworld.org/forums/images/smilies/wink.gif)
I traded PM's with soulsearcher as well...I now have the proper conversion setup in the logger...stay tuned!
