Temperature Modeling

This is the first part of a larger thing I've been working on. The goal is both MAF and Speed Density tuning that works day, night, summer, winter, and at any altitude. Temperature is one of the three components needed.

Here's the paper:

Dunno, that's the big question that's completely stopping me from applying this knowlege and making a full model of it. I know kinda how it works, so I have a functioning model, it just doesnt use the filter table the same way the ecu does. Wanna bug Paul/Ross for me?
