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.
Come on guys---there has to be one person out there who can confirm that I am either right or wrong-----one person----I know there are tuners out there that log boost----come on!!
I fixed my formula and got the following results on 3 different pulleys.
2.8 pulley 10.03 psi Boost
3.0 pulley 8.63 psi Boost
3.2 pulley 7.41 psi Boost
Bump
Its normal...
Thanks
No problem. I would log KPA so that it will be less confusing. Or use the built in boost math that doesnt show negative boost (manifold vacuum) in PSI.Quote:

So to avoid doing a lot of breakout wiring i have just started using a constant for the barometric pressure. With the sensor getting its data from the MAF, is this suggesting an issue with my MAF sensor?
