traction control blows

[Blue1]

So, I figure over 600 miles on the new GT, I'll take it to my top secret testing area (local road between two fields) and get a stock performance baseline with my GTech accelerometer.

Car is probably still a little tight, road surface not perfectly clean (some white salt stains), I haven't aggressively launched a manual tranny in a while, so I figure high 14s @95 or 96 mph.

Shifted inton second @ 5800, got anxious and went to third @5100 (duh), thinking, "there goes two tenths."

0- 60 = 7.0 What??? ('91 LX automatic = 6.1 with no internal mods, stock converter)

1/4 mile = 15.5 @ 94 mph. ('91 LX = 14.8 @93 with GTech, 14.6 @95 mph on a real strip). That sucks. I'm so bummed I didn't try another pass. Halfway home I see I forgot to kill the traction control.

What a moron...

Am I reading this right?.. are you intending to shift at 5800? Try shifting closer to 5000

 

[JonJon]

are you setting it up right?
i had so much problems with the non competition model with the calibrating

Please explain "calibrating" the traction control.

Also, I was under the impression that the 4.6 makes its power a little higher in the rev range than the 5.0. Anyone know peak hp and peak torque rpms for a stock GT?

Thanks,

nono, the Gtech...

 

[Blue1]

I've have nothing but praise for the GTech. As long as it is level and pointing straight ahead, its accuracy is uncanny. I think the traction control just killed my 60' and my 0 - 60 times; the trap speed was there.

Anyway, doesn't anyone out there know the rpms at which a stock '03 GT peaks with torque and hp? No dyno charts? What does Ford claim? Since they give us peak torque and hp numbers, don't they know when those peaks occur?

If you're driving to the grocery store. All of my best passes last summer were made shifting at 5700-5800RPM.

 

[03redfiregt]

I would agree with shifting closer to 5000. Like 5200 0r 5400, somewhere in there thats where peak horsepower is. There is'nt any point in revving past that. Just my 2 cents. But the traction control def did'nt help you.

stock 99+ GT's make peak HP around 5100-5200

i shift at 5800-6k, anything lower with stock gearing isn't going to help in my experience due to the high rpm torque range on these mod motors. with 4.10's you can shift lower. this is a major debate waiting to happen. i say shift at redline.

Everyone thinks they have some kind of factory freak or that they're a prodigy when it comes to racing cars.........

Then you go the the track, get the timeslip, and realize you suck.

Happens to all of us.

i have 2 Gtech's, the regular and the competition. but i know it has limitations like
1) the non competition one is easily miscalibrated
2) the road has to be perfectly flat
3) wheel spin = less accurate readings
4) competition model is awesome

in my 99 GT, stock, i ran 14.0x runs with the non competition model
then i went to the drag strip and ran low 14's until i got a 13.706 run

so if you're using the gtech right (assuming it's a non competition) you are driving like craaaaaaaap
or it's miscalibrated, or it's not a flat road

I just know that changing nothing other than my shift points from about 5200 to 5700, I went from 14.7's to consistent 14.2x's all day long. And my car wasn't heavily modded at the time. Just a catback and I was running on 18's.

BTW, is there any way to have the TC normally OFF so that when you push the button it turns on? They had a mod for the F-bodies when I had my '99 and '01 Formulas, but I've never seen anything for the Mustang.

There is a mod where the car remembers what setting you had it on. So if you turn it off, when you start the car the TC is still off. If you turn it back on, the TC stays on (even if you turn the car off) until you push the button again.

I'll look for a link...

I turn traction control off !

I turn traction control off !

LOSE THE 4X4 and it would look Much better.

OK, I don't think I'm the next coming of Christ in a race car, but I have had numerous hi-perf vehicles and have strip experience.

Getting a bad car is pretty rare these days (compared to years past, anyway), as is getting a performance freak.

To the gentleman who said I'm driving like crap, I would like him to try a run with the traction control on and see how much time he loses...

Not that I'm sensitive or anything...

[GinoGT]

I wasn't saying YOU suck specifically, just how most, if not all, of us have been a few tenths too hopeful with out first pass down the track. I thought my first was a 13.......nope, low-mid 14's. Nothing like getting bitch-slapped and put in your place by a little piece of paper ribbon.

And for the TC thing, been there, done that, felt like a retard. My car bogged to hell on the 1-2 shift, I'm thinking "WTF!?", look at the instrument panel and see the TC light on.

14.757 seconds later the agony was over.

 

[XStanger]

5600-5800 on a stock GT is a more optimal shift point, not 5000!

 

[GinoGT]

I'll try shifting earlier for a couple passes next time at the track, maybe about 5200 or so. I can tell my powerband sort of does a face plant up near redline, plus I think the 4.10's will let me get away with shifting earlier.
