I own a 00' a4 with mti intake and corsa exhaust. I've always been able to power brake and spin them but now for some reason no matter how hard I try "NOTHING". I know to turn off the active handling and I'm on GY RF's so I'm possitive I've lost some HP some where. I'm hoping its a simple fix. Any ideas on what I should check? Thanks :cheers:

 

Turn off the traction control!

 

You turn off the TC not the AH.

 

Usually if the AH is turned off, then the TC is turned off too. So I doubt that is the problem. Have you considered the weather? Is it considerably hotter there? If it is, then you will have two factors affecting your burnouts. A: you'll make less power due to lower air density. And B: You're tires and the pavement are both warmer, which will increase the grip, and prevent wheelspin. Perhaps these are the issues, rather than a lack of power.

I don't have TC that I know of. I push the round button on the center console and the car tells me AH off. Whats the rpo code for tc? And as for as the weather it's been the same all summer, hot. And when I say I used to smoke um I'm not kidding. I went through 2 GR RF's in 7 months. There is something wrong with the power output. Could it be a bad plug? I'm just looking for advice on an easy fix. :cheers:

 

.... :nonod: ..all Corvettes come standard with traction control, active handling use to be an option.
If you have both press and hold the a/h button for 4 seconds, your DIC will say performance mode which means your a/h is on your t/c is off( burn out icon on your dash)
Power brake burnouts aren't good on a regular basis for the rear components specially on a dry surface......JMHO...... :cheers:

 

OK thanks for info but that yellow burnout light comes on a 1/2 second after I push the AH button. So you're saying that the AH button and the TC button are the same? I'm totally lost. :confused:

 

Well its 2 a.m. and I just took the vert for a spin and now understand about how to achieve competitive mode. But here is my problem if I push the tc, ah button for 1/2 sec the DIC states active handling off(which allows the tires to spin or atleast used to) and when I hold it for 4 secs it says comp mode(which is just the same as active handling on, as far as not letting the tires spin). You'll are stating that I need to turn off tc not ah but as far as I can see thats not an option. The owners manuel doesn't mention it and I just played with it for 45 mins. The DIC will only state 3 messages; ac on, ac off or comp mode. Never tc off. Has anyone here read tc off if so then my C5 needs to hit the shop. I'm still new to the world of corvettes and any input would be greatly appreciated. :cheers:

 

the button works traction control and active handling, pressing it once turns trac/active handling off..pressing and holding putting it into comp mode is trac off active handling on..all vettes have traction control, half of 98 and 99+ all have traction control and active handling :cheers:

 

2000 and previous C5s with active handling and traction control need both turned off to get a good spin going. The TC is still partially functional, even in competition mode. Also, if you don't have the 3.15 gears or higher, you're going to have problems spinning them.

 

No, that's what competition mode IS. Comp mode allows you to break the rear tires loose under acceleration, but still keeps the yaw rate controller (for lack of a better phrase) activated so you don't lose control in a hard turn. You're right, the owners manual isn't very clear, but the new owner's video has a real good explanation of Active Handling.

You'll definitely feel the traction control kick in, as the engine just seems to lay down and die for a few seconds.

Hope this helps,
Mike

 

How much can you spin the tires in Competition mode? Wondering if I should use it for drag racing or if the burnout it too long it'll kick off TC.

 

Here's the deal. Traction control tries to prevent wheel spin by sticking a sock in the engine's mouth. It will reduce power when it detects loss of traction. Active handling has no effect on the engine .. it selectively applies braking to individual wheels in order to attempt to keep the car pointed in the desired direction. Active Handling won't cut engine power, regardless of how much wheelspin you get. Comp mode allows you to disable TC, while leaving AH engaged.

 

Yeah, with 2.73s it is nearly impossible to spin, unless you use the break or the wheels are not turned completely straight...or you drive on ice :)

 

Did you get new tires? :confused:

 

Thanks for all the info. I think that my and others questions have been answered. However I've been in my 00', A4, 3.15 G vert all day and when its in comp mode it still has TC on(I'm 100% sure). Its just like one of you said its like sticking a sock in the C5's mouth once I try to power brake it feels like it wants to die just like when its in TC mode. I believe Scissors is correct the TC is still partially functional when in comp mode. But if everyone else believes that comp mode should be opposite and turn off TC then its posssible that Scissor and I need to take take our C5's to the shop.
What do you'll think? :cheers:

 

:confused: Mine smokes at will. :smash:
Brake dust smoke with TC on. :lol:
Run rocks smoke with TC off. :D

 

Late 1998 through 2000 Corvettes had Generation 1 Active Handling. 2001+ Corvettes have Generation 2 Active Handling. In Competitive Driving, you cannot powerbrake with Generation 1 Active Handling, however, you can powerbrake with Generation 2 Active Handling. If you attempt to powerbrake a Generation 1 car, in Competitive Driving, the further you depress the accrelerator, the more the engine will downpower. That's the way it's designed. However, in Competitive Driving, my car will bust them loose and just keep on spinning until traction is achieved or until the car begins to get a little sideways and Active Handling kicks in. That's how it should work.

You are the first person that really know their stuff about this matter. No one else has even mentioned the fact that there is a gen 1 and gen 2 active control system. It all makes since to me now. Only problem is if what you are saying is true then there is no difference between normal mode and comp mode. The TC and AH are on during both. This must be why GM made the gen 2 because gen 1 and comp mode in 00 A4 is a waste. :confused:

 

In each system, Traction Control is turned off and Active Handling remains on when Competitive Driving is selected. While it is true you cannot powerbrake a Generation 1 Active Handling car, it is also true that if you do not powerbrake, Traction Control never comes into play when the wheels are spinning. It is a programming thing. Generation 2 Active Handling uses a little different hardware and different software. It is a little less intrusive system, however, in my opinion both systems are great. Another difference is that with Generation 2 Active Handling, Competitive Driving may be selected while the car is moving. Not so with Generation 1. However, what many people don't realize about Generation 1 selection of Competitive Driving is that the button may be pushed, thereby starting the five second countdown while the car is moving. However, the car must be stopped when the timer times out after the five seconds in order for Active Handling to engage. For example, if you are not in Competitive Driving and are approaching a stoplight where you want it, you can push the button during the roll into the light, just as long as the car is stopped when the timer times out. Try it, it works.
