#230 a Bat out of Hell?

Hey irpq11, what kind of mods are you thinking about? Just a tune?

[Scott@Bjorn3D]

Guys,

GM is still working on my car. I can not go into great detail but lets just say it is not the dealer working on it anymore. I would wait and see what they come up with. This may lead to what they find wrong with mine could help find a fix for others. I would not run out and void you warranty yet if you want to keep one.

Randy. One change you could make that should not void anything but the rear end warranty would be looking for higher gearing like 3.73 for the rear end. That would get you moving alot faster and you did nothing to the engine and the tranny.

irpq -- for refernence, at an estimated DA of 2120 (lowest altitude in Mobile is 10 ft, which I used as the estimate, plus an average pressure of 30 in Hg, average temp of 86, and average humidity of 88 according to wunderground.com), you ran a 13.949 corrected on your 14.3 run. Adjust accordingly for the 14.5.

At least according to this thing, and obviously I don't know what the exact conditions when you ran it were. http://www.dragtimes.com/da-density-...ect+ET+and+MPH

Never mind the MPH, it was just a typical number for that 1/4 mi time that I threw in there, won't affect the calculation any.

13.949....still kinda slow, but it's getting into..."the realm".

Glad to hear they're still working on it. Sorry you're the one having to deal with it though. Hopefully it will be figured out by the time I get my car. October? Maybe!

On my blackberry so can't post the popcorn icon. Can't wait for more details from you Scott. You can't go into detail because you don't know or because they asked you not to right now?

I am sure that something is probably slightly off on your car, but does the fact that you guys are in Alabama in the middle of a muggy summer factor into this a bit? You still have 4.5 or so years left on your powertrain warranty.

Wait and see what GM and the other guys looking at your car say, and at least wait till it cools down a bit in the fall. I have heard that summers are pretty hot and humid in the southern states, and those 2 things are known to MURDER your engine performance.

"Once they find there has been a non-dealer reflash GM will automatically deny the warranty claim, and void the rest of the powertrain warranty."

Subject: Identifying Aftermarket Engine Calibrations


Models: 2005-2009 GM Passenger Cars and Light Duty Trucks

except Pontiac Vibe, Chevy Aveo, and All Saab Models




--------------------------------------------------------------------------------

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:
A dealer may have the need to verify engine calibrations. If a dealer feels an aftermarket power-up calibration has induced engine and/or drive train damage, there is now a way to verify what calibration is currently in the vehicle.

If a suspicious hard part failure is observed in the engine, transmission, transfer case, or driveline, perform the calibration verification described to determine if a non GM issued engine calibration is installed. Non GM issued engine calibrations subject driveline components to stresses different than those that these components were validated to. Repairs to transmission, transfer case and / or other driveline components where a non GM engine calibration has been verified, are not covered under the terms of the New Vehicle Warranty.

Recommendation/Instructions:
Instructions for confirming Calibration Verification Number (CVN)
• Go to TIS2WEB

• Select Calibration Information (SPS Info)

• Enter VIN

• Select "Get Cal ID"

• Select ECM Engine Control Module

• Hit "next"

• Select "Complete History"

• Print

Take Printout to Vehicle along with Tech II
• Plug in Tech II

• Go to diagnostics and build the vehicle

• Select Powertrain

• Select the engine

• Select F0 - Engine Control Module

• Select F4/F5 - I/M information System / Module ID information*

• Select F1

• Compare the calibration ID and Calibration Verification Numbers (CVN) to the Calibration Verification Numbers (CVN) on the printout.

* This step may vary by controller; use the Module ID Information in the Engine Controls.

Although the part numbers will be the same for each, it's the CVN that will determine if the calibration is GM issued.

If ALL of the CVN's are EXACTLY the same, the calibration is GM issued.

If the part numbers match and ANY calibration verification numbers (CVN's) do not match the printout, it is likely that a non GM certified calibration has been installed.

In order to document the case - a CLEAR digital picture should be taken of the TECH 2 screen showing the VIN and the CVN's that do not match the TIS2WEB printout. The picture and a PDF copy of the TIS2WEB printout should be forwarded to ***email edited***@GM.com for verification along with the VIN and the reason the vehicle is currently in for service. Please copy your GM Area Service Manager (DVM/DSM) on the e-mail. GM will verify if the CVN's are not GM issued and respond via e-mail within 48 hours.

If both the Part numbers and the CVN are different, photograph the part numbers and CVN's on the tech 2 screen as described above, assuring the VIN shows clearly in the photograph of the TECH2 screen, and check to see if the vehicle has the latest released calibration. If the latest released calibration is not installed in the vehicle, the part numbers will not match , and the CVN's won't either. E- mail the original Part Numbers and CVN's found in the vehicle on the TECH 2 to: ***email edited out ***@GM.com to check if the calibration and CVN matches a previous release. Recalibrate with the latest released cal and re-check against the part numbers and CVN's that are released.


Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

"And before someone says "Magnuson-Moss", it would be Scott's responsibility to lawyer up, take GM to court, and prove the aftermarket tune had nothing to do with damage to his powertrain. "

To explain that.. well how else do you think he would get GM to cover it if they say no? Ask really, really nicely? If GM denies it for an aftermarket tune, what else could someone legally do besides take them to court?

Whatever it takes to get the performance I was supposed to have when I bought it. If that's a tune, so be it. My dealer still knows nothing helpful. And considering Scotts situation, I don't know what my dealer can do about it anyway.

I didn't agree to buy a 42k car for 'the realm'. I can appreciate your point but even after the correction, my car is slow. And BTW, the V6s are getting the advertised 6.2, 0-60 times. Why are the corrected factors not bothering them? I bought the SS, not the LT.

jAgain. The V6 cars are running WITH my car. If the heat and humidity are inhibiting my car, why are the V6s not affected as badly?

[ElAntonius]

I wasn't dismissing you. Just pointing out that 13.9 is approaching the drag times listed on the top list.

And I wouldn't know about the v6s. I do know that all cars are affected by weather and that I would correct a v6 for DA like any other car.

I also don't know the margin of error on the iPhone across a quarter mile. Small error can get magnified across that distance.

I've been keeping pretty close tabs on the V6 Camaros and for the most part they're not running all that fast in the summer heat. From what I've been seeing, most of them are running high 14s or so in the 1/4 mile. Some are running slower than that.
But that will change with more experience behind the wheel and cooler weather.

I think you'd be pretty suprised if you raced a stock V6 Camaro in a full 1/4 mile race (same track, same day, same weather conditions, etc). Trust me, you will easily win that race.
Based on your dyno pulls, you're car is making a lot more HP than a V6 Camaro.

You just need to get that tune straighten out and you'll have a fast L99. You could easily be sitting at 330rwhp, 340 torque with a tune. That along with a reduction in torque management and your car will be fast.

Today, just for fun, I was playing around with the paddle shifters. I would start out going about 15mph in 1st gear. I would then mash the gas to the floor in 1st gear and then hit the upshift paddle at about 35mph. I would get loud bark and some wheel spin on the shift. It was fun. And it was a good 90 degrees outside.

so this problem is only prone to the A6 cars????

Yup the autos are the only car that get the L99 engine. The L99 is the only engine in the lineup with these problems. If you order (and you did) the 6 speed you get the LS3 and it is not having this issue.

...and then only a very few.
