He said ZR1, as in the LS9 Corvette, will do 10's with DR's.

Maybe do that even bone stock?

They didn't put AFM on these too, did they?

No AFM on the LSA auto. But ya, a good tune on my bolt ons L99 made a big difference. Maybe that's it. But ya it does suck to blow your warranty.

Does anyone know why the car was shifting at 5500?

Because all the safety barriers in place instructed the TCM to cut the shifts back. i.e...The ECM began to see the heat soak and heard the knock so it pulled the timing and began short shifting the transmission to keep it from hitting red line.

Thank you.

Its funny that a heat soaked gt500 runs an 11.8 on over 30 passes and this is considered a "normal" time for it. Yet this 12.6 isn't given the same situation. The guy states he knows how to drive and has tracked his cars before.

Look at all the people around in this and any other thread who run their cars at the track 90 degree days with less power trapping much higher. Something definately not right here.

So my question is: what is the window of opportunity for this car? It seems pretty narrow, and if so, what's the point of debating all these times if it requires such a small window of opportunity to reach said times?

Nice book out called "When the light turns green." Great introduction into drag racing terms and what it is all about.

One other thing to consider, but it may not be an issue with the ZL1, in the diesel racing community (Duramax/Allison) the TCM would learn your driving habits and then adjust the shifting tables accordingly. So for normal daily driving it would smooth out the shifts and even short shift at times depending on the conditions. Then once you get to the track the truck would fall on its face down the 1/4 mile shifting like a crazy person and acting like something was wrong with the transmission. What we had to start doing was either performing a memory dump (battery pull) and make a couple of hard passes before a race or we had to buy a separate TCM that would get thrown in the truck only on race day and it would never be allowed to see normal daily driving. Don't know if the TCM on the ZL1 is doing this as well but I'm sure it is to a degree. But the short shifting that was taking place on Stephen12ZL1's runs was definitely because the ECM was trying to protect the engine in what is saw as adverse conditions. I'm suspecting that GM has the tune set to run conservative until the 'break-in' period is complete to protect against future warranty issues. Ford has done this as well when they started supercharging the Mustangs. Once you guys hit the 1500 miles I would do a memory dump (battery pull) and then see how she runs. I'm willing to bet that the car will wake up and become a beast. Getting a larger more efficient HX and additional reservoir will help as well.

I think in normal drive it shifts at 5500 and sport mode it hits 6000 rpm? Was he not is sport mode?

evolve · 05-26-2012, 01:29 PM

Needs lower IATs...

DangerZL1 · 05-26-2012, 01:58 PM

I talked to a knowledgable tuner who owns two modded CTSVs and he told me that the car would heat soak after one run and you'd be down 30 HP or so after that. He highly recommended one of his heat exchangers for the car. He didn't think the improved ZL1 exchanger would be significantly better than the one in the CTSV. I guess the OPs time would Be representative of what I'd run in the heat at my local track.

9c1ny · 05-26-2012, 01:59 PM

pretty close to these traps-

http://www.camaro5.com/forums/showthread.php?t=226529

hate to say it but the 11.9/12.0 runs that are out there with the 117/118 traps are probably the best this car will ever do stock except in negative DA, these mid 12s/ low 13s w 110 traps is going to be the norm

I don't know about losing 30 hp.

I've raced my 2005 LS2 GTO and 2009 LS3 G8 GXP (both auto) many times and I can guarantee you that heat soak will set in. My MO for racing is make 2 runs, let the car cool for at least 30 minutes, then run again.

The car will not get faster if you're making consecutive runs, unless you really blow a run, then come right back with a good run. With both cars, I've set a standard of never running the car with water temp over 190 degrees. I've found that after reaching that point, you're just beating the car up and the time slips aren't showing any improvement.

To the OP of this thread, give yourself and your car another couple of chances to run at the track.

Cool! Thanks for the suggestion.

speedmon · 05-26-2012, 02:52 PM

Does that car have a boost gauge? What kind of boost is it pushing at stock settings, like 6?.......Sounds like it needs more boost....like at least 9 or 10.

But if you're going to void the warranty, like some else said......may as well do it with an SS and save 20K.

The body looks really cool though, cool wheels, and I want one of those suede steering wheels.
