2010 Camaro 1SS LS3 M6 won't spin tires

Some people think punching it mid corner in first gear with everything turned off counts...it doesn't.

yea i was disappointed to when my M6 didnt light em up from a first gear roll, considering i bought this instead of a 2006 vette. this car really doesnt start putting down power untill about 3000RPMs. i have a vararam and a muffler delete feel alot more throttle response but i still cant roast them in first unless i drop the clutch witch i dont like doing...alot. personal opinion is get a supercharger, cam, or headers. good luck with your tune.

I'd still take my '12 SS over a 2006 Vette in a heart beat! The LS2 was one of GM's under powered engines, IMO. The LS3 Vette should be able to spin the tires from a first gear ruoll with no problem, mainly being so much lighter!

From a straight line no corners and just traction control off I can break my tires loose without dumping the clutch 1 st- 2nd and at night when it is cooler its even worse

VHT comes to Alabama(and other key sites across the nation) for research and development.....lol

How much air pressure is in your tires? What tires? Stock gears? Engine mods?

My heads/cam/longtubes/FAST 102/Vararam/3" X pipe with no cats car, with stock gears, and stock weight, on Nitto NT555r stock size drag radials WILL NOT spin...everything turned off...without help from the clutch pedal. I haven't driven it with this setup on the stock tires, and I don't plan to...but I do plan to put it on regular street tires when these are through and switch to an 18" drag wheel/tire setup to save some weight.

When it was a bolt on's car, including the same exhaust it has now (Kooks 1.875 with complete 3" duals with an X) and the Vararam, and running mid 12's, trapping mid 1-teens, on the stock Pirelli's, at the 36 PSI that the door jam says to run, it'd sorta squeal a little in first...sometimes would wheel hop...but would just hook in second...shifting it as hard as possible, it'd bark second pretty hard, it'd bark third pretty hard too...but that's not breaking the tires loose. My car has never been an underperformer...when it was stock it made good numbers and ran good times, when it was bolt on's it made really really good numbers and ran great times, and now that it's got a ton done to it, it hasn't been to the dyno yet, but it certainly has been performing everywhere else.

I started from the factory AFR of 11.x:1 and have been working my way up to 12.5:1. The knock sensors have been pulling timing above 4200 RPM regardless of the AFR. My tune right now varies between 12.5:1 to 13:1 depending on the RPM. Up until just recently, I never went leaner than 12.5:1 to be on the safe side because of the knock sensor pulling timing. I had to try to rule out everything else before I finally made up my mind to desensitize the knock sensors. Thanks very much for sharing your info on the AFR and timing. That's almost exactly the numbers I'm trying to get to if I can get these damn knock sensors to quit fighting me.

Don't think you said this in this thread, but you try race gas yet to help at 4k?

I wouldn't bother going as lean as 13:1 anywhere...I tried to shape my PE to match my torque, give it the most fuel at peak torque, and lean it out in the other areas...it made absolutely no difference in measurable output on the dyno (3-4 hp maybe...which can be just from making multiple pulls anyways)...but what it did do, was make it a lot harder to avoid knock retard at full throttle...I went back to the flat PE, and the car hasn't had knock issues since.

I guess it's possible that you've got a bad sensor too? I'd try 2 things...first at the dyno with good fuel in the tank, I'd disable knock retard, make a pull, listen VERY CAREFULLY to the engine, and pay very close attention to the TQ curve...if it's not smooth, or you hear it knock (1 pull won't blow it up...not that I advocate letting it knock, but I really doubt it'd hurt anything)...then there's a problem with the engine...bad spark plug(s), bad injector(s), bad coil(s)...something that's actually causing knock and the sensors are saving you, and you need to track down the issue/problem...at that point, re-enable knock retard and then try to track it down.

If it IS smooth and sounds normal through the pull...order a pair of new knock sensors from GM, install them to the letter from the GM manual...check that their wiring to the PCM is ok (I'm sure it's fine), and see what's going on there.

I did note the changes to the knock sensor calibration in the newest iteration of the LS3 Camaro as compared to my 2010...but I haven't needed to make any changes...they've worked when I ran it too lean, and they do nothing intrusive to me when the AFR and Spark is right.

How about posting some videos of the cars that can spin'em while rolling? I'm not questioning that it can't be done, but just want to see it. Only the tire and I know you'll be in your driveway .

Im cammed and no spin, these things arent nearly as beastly as people think

If you only drive them once a week, and spend the other 6 nights getting too much tire shine all over the tread...they'll spin.

They're heavy cars, and the suspension plants the tires pretty well...they like to hook.

MikeOd thats awesome! Yup your right, theses bad boys arent the lightest cars and with sticky meats you usually just dig and go..But I still think a lot of guys on here think they got an SS and there going to destroy the world in it. Great cars but still underpowered imo.
