Math Wizzards - BEN Factor IAT correction
I performed an experiment today with the BEN factor. My car had been baking out side for the better part of 9 hours when I left work. I flashed the changes from this mornings log, fired her up, let her come to full operating temp, then started logging. I noticed the BEN factor at idle was 1.02. No biggie, I'll just fix it when I get home. When I got home, I started a new log while I was idling in the driveway. BEN factor 1.00.
I went back to the data tab of both logs and noticed: The first log had an average temp of 104*F and the second 97*F. Even better, this mornings log had an average IAT of 84*F.
So now I'm wondering, is there a mathmatical formulation that can be done to correct the BEN factor to a given/fixed IAT?
My VE Table is close, but I feel like I'm chasing my tail now...

I am also seeing a difference in the Ben factor with different IAT. Do you think we should only log values that are below a certain temp? What do you think that number should be? We could apply a filter to weed out the higher IAT counts..
