I made an attempt at logging Boost on my 2000 GTP, but I am getting negative readings driving around town and a positive reading of 7+ under hard acceleration. I am attaching a scan, and my scan config.
My Math Parameter setup is Manifold Absolute Pressure 50030.98 - Barometric Pressure 50032.98.
Would someone with more experience than me take a look and see if I set it up right?
I am using Barometric pressure and MAP to create my Boost graph.
