What is ASR? What does it really do?kiztope 10-01-2003, 03:59 PM i just got a '99 Z28 It has ASR... I know it is a traction control, but how does it function? What does it do?? :confused: I'm loving the LS1......:bow: SFB767 10-01-2003, 04:04 PM ASR is pretty much traction control. If you hit the gas too hard, it'll apply the brake to the spinning wheel, push the gas pedal against your foot and the LOW TRAC light will come on. I also believe that it holds the car back too. I've only driven with it off a few times and it feels like the car accelerates faster with it off. Lan01z 10-01-2003, 05:10 PM Originally posted by kiztope i just got a '99 Z28 It has ASR...

In the rain or snow it keeps you from fishtailing when you give it too much gas. Other than that its best to leave it off. On mine the power is pretty much the same on or off. It only kicks in when I floor it and the rubber doesnt connect with the ground.

I'm not going to dispute, 'cause I don't have ASR in my car, but are you sure that the brakes apply?:think: I thought that ASR would simply reduce engine power until traction was re-gained, but I didn't think that it was advanced enough to actually apply the brakes??:confused: (remember, we're talking about the F-body, NOT a 'Vette!!:p).

When I had my tranny worked on not too long ago, my car was on the lift and the dude was moving the rear tires and each one moved in the opposite direction from each other, so I asked why. He said because my car doesn't have posi-traction. I told him I thought that's what ASR is. He said that ASR applies the brake to the slipping wheel.:confused: Beats the hell out of me, this guy KNOWS cars so I'm sure there's a shred of truth to what he told me.

The computer kills the engine power ;) Aklaim 10-02-2003, 12:57 AM Traction control kills engine power......if it were to apply the brake to a wheel with no traction you would spin when that wheel found traction. 99blackSS 10-02-2003, 02:15 AM I hate when I am driving and I hit a slick spot and the thing kicks my gas pedal up. Makes me very angry, it seems like hours before the traction control light goes off and lets me get on the gas again. GoFast908Z 10-02-2003, 02:26 AM My ASR is my foot coming off of the gas petal (which is not often :D ) :rolleyes: Aklaim 10-02-2003, 02:27 AM Does it also feel like you dont have the same power after the light goes off?? I swear that i lose timing every time i go Lo trac, and the computer doesnt give it all back to me when normal driving resumes....but it could all be in my head too.

Hmmm, well all Z28s came with a limited slip diff. You dont have posi-traction as in the locked unit from the old muscle car days but punch teh gas and both tires will spin. A lot of people use limited slip and posi interchangably so I'm not sure what he was trying to say when he mentioned you had no posi. 99blackSS 10-02-2003, 02:54 AM Originally posted by Aklaim Does it also feel like you dont have the same power after the light goes off??

Yeah, thats probably to keep you from loosing traction again moments after the first slip. When I slam the gas right after the light goes off the RPMs take forever to climb and the tranny doesn't downshift, its emotionally painful for me.:cry: CODY BEHNKE 10-02-2003, 09:00 AM SFB767, That shop must have no idea how a Torsen Diff. works. It has no pre-load so when in the air 95% of the time the wheels will spin like it has a open Diff.

How does a Torsen Diff. work? 2001SilverZ28 10-02-2003, 09:39 PM I've never had to use it, even in the rain. But I guess it'll help if you can't control your foot and must punch it while driving in the rain. 99blackSS 10-02-2003, 10:15 PM Originally posted by 2001SilverZ28 I've never had to use it, even in the rain.

ASR automatically turns on every time you start your car. 2001SilverZ28 10-03-2003, 12:53 AM Yeah, but I turn it off. 99blackSS 10-03-2003, 01:02 AM Originally posted by 2001SilverZ28 Yeah, but I turn it off. They make a thing that defaults it to always off that you might be interested in. 2001SilverZ28 10-03-2003, 01:19 AM Yes, I am interested in something like that. 99blackSS 10-03-2003, 01:57 AM Originally posted by 2001SilverZ28 Yes, I am interested in something like that. Thats nice, I can't tell you anythign about it.:D Let me see if I can find it again. EDIT: Its $50 second from bottom on this page.

In a parking lot I broke the tires loose.... The instant that I did, the gas pedal was shoved back into my foot and traction was restored... That is some neat stuff! I like all the cool stuff that these cars have! :bow: :D 94BlackBowtie 10-06-2003, 01:30 PM What does "ASR" actually stand for? 99blackSS 10-06-2003, 02:20 PM Originally posted by 94BlackBowtie What does "ASR" actually stand for?
