Interesting Stall Converter data

[g8_795]

I thought I might share this data. I grabbed the data from one of my runs at the track. I didn't realize that the TCC was locking when I was holding third until I saw this graph. I have since disabled it from locking.

I think it would be interesting to compare the same data with stock stalls and other vendor stalls. Anybody have HP Tuners that can plot the same type of graph?

The first graph is measured transmission ratio vs "Ideal" transmission ratio
The second graph is Engine RPM vs Trans output RPM.

Sometimes locking the converter on the big end will net you a higher trap speed. My Camaro would lock up at 100 mph at WOT.
