My 2000GT Questions

[case12]

...Thus the reason I put this in off topic lounge. But you guys are usually great with answers, so I thought I would give it a try on this forum:

I recently added a set 9inch wide wheels on the rear with brand new 275 F1 eagle D3 GS. Fronts are standard 8 inch with same tires except 245's still in pretty good shape.

That is all I have changed, and since have noticed two things:

1. When braking in slow speeds, the car now starts to pull hard to the left OR the right OR not at all. So, is this the older front tires, bad roads in Chicago or traction control?

2. In two cases, I have shifted hard into second to accelerate in a turn (to get out of the way of oncoming traffic). In both cases the engine "bogged" down similar to when traction control comes on in the snow. Frankly, I was sweating it so much to get out of the way, that I didnt see if the light for TC came on.

Last question is what do you guys think of TC - leave it on, or turn it off?

You guys know I am OCD - but in this case, having the engine bogg down when accelerating in a turn can be dangerous. And it had not happened before.

Any wisdom? Casey

Casey,

I wonder, were there sensors on your previous wheels? Not sure how the new cars get traction data to the on-board computer.

Traction Control? It's a good thing. It's nice that they give you an on/off switch (sometimes)for it.

I had traction control on a 2001 Toyota Sequoia 4.7 V8 that we used to have. Had Flowmasters on it. It sounded nice. But it was not possible to spin the tires because of the TC.

Hi Jeff - finally someone attempted an answer.....I was wondering if I had an oddball question.

....no sensors on the wheels.....i also switch out to snow tire/wheels in the winter with no changes.

....traction control i think controls engine spark, and maybe brakes (?). in the snow i definitiely have cases where engine spark slows the (engine) and wheels down to keep from spinning. many think this is good on dry pavement as well.

.....my new problem is traction control seems to control (reduce) engine performance in some hard accelerated turns. i was looking for inputs on whether i should just turn it off and only use it in snow. there are different schools of thought on this.

....just wondered what this group though about the use of TC.

(you are correct - a burn-out definitely needs TC turned off). Casey

I've been busy so haven't been around for a while but I would turn the traction control off and then go out to a deserted parking lot and try to
recreate the problem. Set up a "course" and run it both TC on and off and
see what happens. That should tell you if the TC is causing the problem or
it's something else.
