Weird!? Sports mode should change 1-2 closer to 60kph not 48?!
Cue to 1:22 (not first but second change) and listen to the pause in shifting 2-3, half a second. Is that what happens in the Sports Mode Auto with a stock MSE?
View media item 3185300 shift points are useless in LS3:
View media item 319main thing is look at the LS3 (green) recovery RPM, well below torque curve.
Needless to say 5300 is well below 5900 stock LS3 HP peak, which happens to be closer to correctly meeting torque curve on recovery RPM:
View media item 321To put that in perspective, this is the best you can hope for shifting at 5300:

Holding it in gear:
View media item 325
So the test was not flat-out outright, KIA revved 500 past it's HP at 6000, VFII revved 500 rpm below peak, to 5300. You can rightly say the KIA was being caned and the VFII hardly near its limit, and that sounds awfully like an excuse given the hard data. But it's a fact.
Be that a fault of the driver, conditions, the settings / mode, but a 5300 shift in a 6l80 recovers before torque curve starts (not 'on cam' dome in first graph above) if that is stock it sits way too low for shift recovery (plus a suss 2-3 stutter likely TCS).
Verdict: Clearly shows crappy trans tune of the VFII as-is, tarnishes the potential of this car. I suggest if your car shifts remotely like this that you get a proper tune for 5700-6000 shifts (peak HP). Simply holding in gear longer or manual shift and a drastically different result.

Nope. The stock tune will shift past 6000rpm in standard mode. I.e. no sports shift.

So how on earth could the driver change into 2nd at 48 kph (5300), and the shift into 3rd cuts out (?!) for half a second or so at 98 (5300)?
I think the driver either was not completely on it or not in the best mode.

Yeah it looked a bit odd and didn't sound like WOT all the way. Where did you get the revs, change points and speeds from?

Speed data VFII from HUD zoomed in on retina desktop monitor, same zooming on tacho of the KIA. Not that I'm obsessed or anything :rolleyes:
The other infographic is media I've used to explain stuff (mainly to you:p) before, is all here.

Geez that's a good 1/4 mile time for the Stinger. Even low 13's for the SS isn't bad.

I used to remember not too long back anything that could crack 14's was considered a beast..

Can't really hear much of a pause in the change @1:20 to me monstar?

But if he only revved it to 5300rpm WTF was he thinking?
