Scaner

Not sure where this post should actually be, but I'll start here and see what happens. Have Pontiac G8 GXP with TVS2300. Trying to get some real world data when driving and pushing it. Running scanner and recording, RPM, MPH are working but during playback there is no data. Also, MAP is a 3 bar in the car and my Aeroforce gauge is reading the right vacuum / boost, but the scanner doesn't read correctly. I set two up, one reading PSI, max 15# and one reading in/h2o. one should be at zero at any one time, but the both read wrong. Scanner doesn't register gear selected, etc.

I assume I'm doing something wrong, as someone would have flagged this long ago, but if some information is wrong, I have to question it all. I'm looking for some direction with this and any "constructive" help is appreciated.

Thanks in advance.
