I personally haven't tried it on mine but I did do launch control in it once.

I promise you I have driven cars with a no lift shift, easily done on the 1LE shifting at regular RPMs no issue but WOT like at the track, not a chance. Plus one of the fun parts of taking a manual to the track is perfecting that shift and being consistent.

Again, not promoting it as an everyday driving technique, but unless C5 Corvettes and Gen 4 Camaros and Firebirds had this "no lift feature", which I do not believe they did, occasional use of no lift will not hurt. The WS6 we just sold had about 180k miles on here, and no tranny issues....for what it is worth.
I do agree with your comments about making the perfect, consistent shift being rewarding, and if the car is going to be drag raced a bunch, I am sure I would not want to "no lift" all the time. I was more thinking a max bonsai type run to see what you could get out of the car. If you are using drag radials, and bogging the car a bit, a higher RPM launch would seem to help, but I am sure you knew that. My fear is the car hooking and going, and something breaking at that point. Best of luck, and I am looking forward to seeing how you do.

What I'm trying to say is that I've tried...off track...just to see how it did and it rejected every time under wide open throttle. Someone trying at the track would not be a good time

[Meltdownaverted]

If you want to add your times to the 1/4 mile fast list it's up now for 1 LEs

[OzzySS]

i guess i'm just ignorant of the 1/4, but what is "no lift shifting?" and the programming being mentioned?

[Meltdownaverted]

Leaving you foot on the gas while shifting. Essentially saving you a little bit of time on the 1/4mile

[CrystalRedTintcoat]

I'll take own anyone who wants to no lift shift.

The ECM basically knows when you shift and reduces timing for a split second allowing you to remain WOT.

[OzzySS]

Ah...that's what I was guessing. Thanks

I had >200 drag strip passes on a 96 Corvette with the ZF6 trans. No lift shifted for almost all of em. Never had an issue, car never gave any trouble. YMMV.

Well you and power shift any manual car for example, that simply shifting but never letting off the gas. You'll hear the engine rev up between shifts.

Congrats on the ET. In the fall take out the extra weight and you'll probably go low 12.8's.

I went 13.15 stock in my auto, but I also was able to cut a 1.95.

On that note how does Motor Trend run all kinds of 13's in SS's but 12.7 in a 1LE? Or should I say does all the 1LE stuff help or hinder like a few people think it does?

Yes 12.7 at 112. Funny thing is MT has always been kinda down on the Camaro (and high on the Mustang) till the 1LE.
My guess is the 1LE rear may plant better than an SS without the 1LE package.

It's downright funny how fast Motor Trend puts their foot in their mouth when it comes to tests these days. Carry over model year cars can be the cat's ass one year but complete junk the next. They've changed their opinion of the Mustang & Camaro in every test they do.

As for SS vs 1LE I think it's the different combination of the 3.91's, stickier tires and size. My 2012 SS seemed to bog without really aggressive throttle control. But thats what you get with 3.45's and tall tires on heavy wheels.

I agree that the tires, lighter wheels, and rear end help the 1LE over a standard SS. If the suspension of the SS is a bit softer in the rear (which I assume it is, but am not sure), that would be a plus. The stiffness of the road race inspired suspension of the 1LE is not what the doctor ordered at the drag strip. It has to kill weight transfer.

Cody, thanks for the tranny pictures!
