Not braking traction like I thought it would

[TprGTO-[Robo Fuzz]]

Last night I went to my friends business in an industrial park. He wanted me to check out the new intake on his 2003 C-5 Vette. As I was leaving his girlfriend said let it rip. So I put the A4 Goat in drive and put the gas pedal to the floor. To my disbelief, the car did not peel out at all, or even break traction. I turned around, lined up again, and this time put the car in 3rd. This time, it let out a little bark and thats it. The T/C was off both times. I thought this LS1 motor was supposed to put the power to the pavement and let loose some rubber. Big dissapointment. What could be wrong with this car?

I have the same problem. I took off like a bat out of hell but no tire spin at all.

Thanks for the link.

I have had no sensor lights come on, and no thunk in the trunk. I am extremely dissapointed because my 2004 Grand Prix GT I traded in could easily brake traction and yet this beast can hardly do it. :mad:

This car 'learns'.
Remember the article, where the reviewers had to unplug the PCMs in between runs to get the best efforts from the car?
These are A4's right you guys? The BCM and PTM modules control the drivetrain and there is TM and Abuse prevention stuff built in, some of which is not in the M6 version.
HP Tuners makes the cure. DY and Holeshot figured out how to anesthetize it so you can have your car back from the friendly digital parts preservation gremlins in the computers. Your car has a conscience... :eek:

If you got an A4 just power break it a bit first then let it rip. The TM in A4 cars blows.

Most people I know with RWD vehicles are happy when they can't break traction with a high-powered car... :sneaky:

Yep, that's actually a good thing :)

Ya but theres a time to HOOK and a time to lay rubber! :thumbs:

[Speedy Gonzales]

Stall it up with the brake then put gas pedal to the floor, TC will apply ABS so leave off, and make sure its in Power.

Maybe Mr. Old Goat has an answer here? Try pulling the fuse to the PCM for a few minutes. Maybe that will make the car 'forget' the leisurely cruises you took last week, and 'learn' that you like to smoke the tires. Just a thought....

Would disconnecting the negative side on the battery for a few minutes reset it also?

Yep, same thing. Easier to pull the fuse though. It is just above the battery in the black box. I think it is the top red fuse.

[Dbluegoat]

Thanks Warren,

I will try that next time.

Now I know why the M6 was a 'costed' option...

I guess my A-4 hasn't learned how to keep its tires stuck. As I mentioned on a previous post after reading about this issue I tried my car in Drive, TC off, on a rural road, no brake torque, slapped the pedal to the floor and spin hard for 40 feet before hooking up briefly, spun a bit on the shift to 2nd at 6000. I have yet to try the 3 start from a dead stop, but the car really yelps the tires going into 2nd on the freeway onramps on the 1-2 shift with the gear lever in 3. From previous drag racing experience I know this isn't the fast way down the track, but it can be fun at the right time. Of course, for some reason my average fuel mileage for the first 700 miles is 13.4 mpg. I may need a tire rotation when I change oil.

[GTOME]

I was discussing this issue with a mechanic at my shop. It appears those of us with early build dates can't get the tires to break loose. I can't, Nov. build, TprGTO has Sept. He can't. JRM346 Built Dec. "slapped the pedal to the floor and spin hard for 40 feet before hooking up briefly, spun a bit on the shift to 2nd at 6000." My guy says to ask the service guy If there was a new map written and to have them flash the comp with the new map.

As far as resetting the PCM, did that and it is better but no Pontiac Excitment. I did manage to squeal the tires on take off and chirp 2nd At about 3/4 throttle.

[T.Vick]

After reading this post, I took my car out last night to try a few different launches. My car has a December build date and only about 300 miles on it. All were with TC off.

Launched from idle in D, little squeal, not what I would call tire spin. The car did feel a little held back (TM?) for the first second or two.
Launched from idle in 3, little squeal, not really any different that the first time. This time it did seem to pull harder right from the punch though, like the TM may have been reduced.
Last time, in 3, pre-loaded the converter to 1500 RPM, let the brakes go and jammed the throttle to the floor, little squeal and the car launched. The rear squats and the from lifts, the car pulls hard and has great traction. No clunks or strange noises. I'm very happy. The hole shot is where many races are won.

Gee I have this problem too........having too much fun.

[DANSLS1]

I'm up to 3100 miles with my M6 and I'm averaging just under 15.5 overall. Note - that's actual calculations as the DIC seems to be about .3 mpg low...

Seems really low... I have just over 4K now and have been averaging 23.5. And my DIC calculations have been right on the spot - one time it said that I used 15.5 gallons, and I put in 15.6 gallons and could not put anymore in.

[DANSLS1]

Remember, over 1/2 of the time I'm driving currently entails sitting in traffic with a high of about 15 mph. When I can actually drive and maintain speeds - it looks like I'd get high teens or low 20's easy - with pure highway mileage going up from there.

Wow you must be doing mostly hwy driving.

[Warren]

Wow you must be doing mostly hwy driving.
A lot of the miles I have on my car are highway miles. 100 miles to my home town and back, 260 miles to KC and back. I also pop her into neutral when I know I will have to slow down for a rural town about a mile out. I figure that saves me both gas and brakes.

I have also taken it to the strip and run the crap out of it. Last fillup I did, the DIC said that I avg 22.3, and the milage/gallons put in confirmed it. This was the day after I put 5 runs in. I KNOW that when you go WOT up to 5600-6K RPM, you are not getting 20mpg, so I think my car may be just special. :sneaky: :confused: :thumbs:

as we all do.

I'd say your mechanic gets a cigar. I'd bet there is a different one. My car is Dec03 and is overcontrolled. I wonder if Pontiac will admit to two maps if there are? I will approach my Dealer and ask him to go to Art Spong.

If you can lay it to the floor and not have any wheel spin, i would take it as a good thing......maybe

From what I was told they won't replace a newer map with an older one.

If they won't, someone else will. :sneaky:

:wall: If you have the A4 and want to peel the tread of your tires just do the HP TUNERS software and you will be set to go.

Christine would spin up across the intersection with T/C off before
DY flashed her (build date 09/03)
And after her Flash she has even more Balls than before. :D
I am extreamly happy with HP TUNERS software. :cool:

How much is this HP tuners software? Is it a handheld like predator or hpp?

[Holeshot]

You will need a laptop

What do you mean MAPS?

[T.Vick]

Possibly another variable, have all these cars been shipped over with the same tires? Mine has BFGoodrich, g-Force TA's. Usually the literature for a vehicle will specify a size, not the brand.

[Old Goat]

What do you mean MAPS?
Digital mapping for the fuel ratio, spark curve, etc.

[derf]

I have no trouble, wagging the tail out at will with my M6.

I'm going to have to replace the tires soon if I keep this up.

When I'm doing mixed city/highway, I get around 17. Pure city gets me 15. Screwing around like a teenager gets me much less than 15. Cruising like an old fart in the slow lane on the freeway nets me high 20's. Cruising like a 30-something YAM on the freeway gets me mid 20's. "Spirited" highway driving nets low 20's.

[stss95]

When i bought my 2000 Ram Air T/A A4 it couldn't spin the tires off the line itself. The car ran a 13.6 stock. These cars come with tight torque converters I think mostly for gas milage and the LS1 is a high revving engine, I changed my torque conveter to a Vigilante 3200 stall the car could burn the tires up anytime you wanted and to back that up the car turned a 12.6 in the quarter mile. If you want more low punch get a stall converter. I am not sure what gears the GTO's come with but my TA had 3.23's in it but with that much converter you don't need to change your rearend gearing.
