Using the data on the Honda web site:

gear...|....2012....|....2011....|....ratio 2011/2012..|....2012 ratio to next gear....|....2011 ratio to next gear....

1st....|....3.267...|....3.267...|....1...............|....1.601470588................|....1.533802817................
2nd....|....2.04....|....2.13....|....1.044117647.....|....1.427571728................|....1.404087014................
3rd....|....1.429...|....1.517...|....1.061581526.....|....1.331780056................|....1.322580645................
4th....|....1.073...|....1.147...|....1.068965517.....|....1.292771084................|....1.245385451................
5th....|....0.83....|....0.921...|....1.109638554.....|....1.282843895................|....1.39757279................
6th....|....0.647...|....0.659...|....1.018547141.....|...............................|...............................

So basically 2nd is 4% taller, 3rd is 6% taller, 4th is 7% taller, 5th is 10% taller and 6th is just 2% taller. Overall the gears are more evenly spaced. It's going to be a slightly more relaxed, and easier drive through the gears at low speeds. It's also going to feel quicker in 6th on the freeway.

I'm surprised that 6th is almost the same. I expected it to be taller than that in the 2012 to get the claimed HWY mpg. I wonder if the real world mpg actually went down?

Looks like the TSX guys are tuning to 7600 rpm safely..the extra 500rpm might give a few more mph, ill re-do a new chart to see speed in each gear at 7600 at some point.
