Great suggestions folks. I may have to do some minor reprogramming but not a big deal.
Run #2 at t=1471s is when I actually pulled into the drive way and shut the engine off. The FIT increased because the heat from the engine actually finds its way out past the fan
It decreases again because I started up the engine to adjust the idle and then shut it off again ... cool to see that in the graph though
The AAT probe is mounted so it just pokes out past the intake grill on the decklid. I've got lots of wire so I can reposition it but want to keep the wire length short as to not introduce additional noise.
I'll try to get a full run in this afternoon with RPM data
