my problem is that i cant do a burn out or even brake the tires loose at any speed the traction controll button dont turn off or on nothing seems to be working properly i track this car and sometimes weekend warrior. i had it tuned and all is good but still cant do a freaking burnout push brake in car goes to 1800 rpm thats all and also wont launch by holding the brake and giving it gas and i was told the ebcm is bad and thats what is causing this by my tuner told be this.so what can i do to get rid of it do i have to tune it or can i do something re wire something etc to bypass it so it dont do anything like retard my timing set the brakes etc?? im literally losing my mind lol also what other issues would do this?? not allow me to do a burnout or launch the car taking any and all answers thanks

cam,headers,stall, etc...

You have an automatic car with the economy rear 273.

.. all you can do with a car like this is put alittle puppy chow in the tank., or change the differential.

Funny.....needs a 3.42 That will wake her up.

Sounds like the traction control is holding you from powerbraking. You should be able to turn TC off and powerbreak to get it spinning. If nothing happens when pushing the button maybe the wires are off of it in the back of switch. Sounds like you need a better mechanic.

The gears will help also, but you have another problem.

grantv

Agree with Forcedvert, even with lazy gears you should be able to get rubber if TC turned off.

You can find the switch/ button pretty cheep used if that is the problem.

Something is definitely wrong. I haven't tried a burnout in the Vette yet, but I had a '96 Impala that was 6300lbs, 260HP, and 3:08 gears that could easily do burnouts.

I can burn out at 50mph with the traction control on with just an LS6 engine and A4.

Something is wrong.

ok so none of these answers help me at all dont point me in a direction besids there is a problem thats obvious ... i read several forms here and ima just post this in the tech side need someone with hp tuner or efi live knowledge theres no reason it should break them loose with the gears it has etc made close to 400 whel and shouldnt bog down no my tc dont work and ther eis faulys and is believed to me my ebcm need to fix that first obvoiously but hard to comeby on a 99 so i jsut want to set different parameters and see if it will work but before spending 100 plus another 100 for my tuners time i wanna see if that will work so all of theese answers are completely irrelevant not trying to be a dick

Was torque management removed with the tune? My A4 with zip tie mod and corsa cat back will spin the tires, but not even close to as fast/long as other cars I have had with less HP/tq. I've been told the torque management really makes burnouts on a A4 C5 pretty hard. I have a 3.15 rear, BTW.

not to be a dick either, but you keep asking for help but you don't seem to listen to the guys that are trying to help you, like in the other threads you posted you were told how to post codes. that is where you need to start if you want answers

Over my 16 years here. many members with an A4 with eco gears complained about not being able to break the tires.

Trying to read this is torture, also.

I will say this, if the tires are good quality. I stated with a 2001 stock A4 on worn out Goodyear run flats and the car spun the tires easily on any pavement with the 273 gears, no power breaking required at all. Then I put on Michelin pilot sport run flats and the tires would not really spin without bringing up the rpm by applying breaks (power breaking) then they would spin but not a lot unless you stayed on the breaks. Car had to have Tc off or be in comp. mode.
My very first performance mod was 342 gears and a slightly higher stall. This made a huge difference in the car being able to smoke the tires at will with the engine still stock, no power breaking required and it would spin all the way through first gear. Not sure what else may have changed in tune as the programming required for the new gears was by way of a handheld tuner to correct shift points and I did not do any of the work myself.

All this being said there is still obviously something wrong in this case, especially if the op has tried to power break car and it is really at 400 hp to the wheels.

But....
Gears do make a big difference on a A4 and they would always be my first recommendation for a big performance boost on the SOTP dyno.

Good luck op I hope you figure out what is holding you back.

This is in no way an attempt to take a shot here, just an honest first hand experience.

I did this when I discovered my 03 was anemic. Did H/C, headers, 3:42. Eventually swapped out the A4 for an MN12.
Now, I'm very happy and it's a smoke show at the flick of an ankle.

Who me?

alright codec1255 hc malfunction ebtcm.. checked power and gounds all is good. the ebtcm is bad what are my options?? im going to my tuner tuesday and wondering if all he has to do is mess with the tq management or what to get rid of it? and will that allow me to do a burnout... sorry for the bad spelling i work till 2-4 am most nights and usually beat from work... taking all answers

Evil-Twin

There are three issues where an eco rear is not ideal.. black top surface, performance tire , underinflated tires.. any of these will increase the coefficient of friction to the point where the torque value is lost through the eco gearing.. Conversely, reverse engineer this .. hard tires, over inflated tires on a cold concrete surface and you will break those tires because there is a reduced coefficient of friction.. less resistance to hook.
