Postby weapon-X » March 19th, 2008, 2:28 pm

eh quite follow your thinking, but here are some of the things i did, when driving mine.

* leave overdrive off
* gear down to 2nd before i take my foot off of the brakes, after cornering
* never depress acclerator so deep, that car will kickdown into 1st.
* never pull selector into 1st
* resist urge to keep foot planted on accelerator coming out of corners, instead carry it down gradually just before it will kickdown, just barely feather it, until it passes the speed for kickdown into 1st gear.

it would depend on the course, I guess......a tight course might get better results from running in 2nd than a fast course...........dunno........manual FTW

I disagree
for a short course where you need to keep your revs up and not get bogged down into third, keeping a traditional auto in 2 will give you better times

Tiptronic is rubbish

In the Mini at least, I have seen better times in 'sport' D than in tip (and not just me)
Also with a conventional auto, it stays in 2......most tips will 'upshift' if the brain thinks you revving too much, and most tips have a lag between shifts, which costs you time on a short course

A tranny with tip is just a toy for driver amusement, IMO

nah man, tip upshifts instantly (in my experience), and holds the gear till u change, except when decelerating - it downshifts automatically. The only problem is that sometimes you will need first gear, and then u have to slow down too much to downshift - i don't know if the same limitation exists with regular automatic

yours must be programmed by an enthusiast
I find the tip in the Mini to be rubbish............it shifts slow, and automatically upshiftswhen you hit the preset rev range.........even in SD the shifts have an annoying pause
I tried the tip in the new A4 1.8T and found it to be equally silly.........
I am sure my AE111 can outaccelerate the Mini, even with the mini having more BHP

What I did to get the automatics to run good times was the following:

1) run in "2" so that the car does not change to "D" and thus does not have to hunt for a lower gear as much.

2) I generally do not manually shift to 1st, if it does that by itself, fine.

3) In attacking the corners, approach the corner, brake before the corner, let off before entering the corner at the speed you want to be at going through the corner, then step into it just before the apex so that the car will respond just as you hit the apex. Use smooth lines so as not to scrub off any speed which will be necessary for the corner exit (for less powerful cars, sometimes a wider line will give you a better exit speed)

4) With automatics being slower to respond and sometimes not downshifting when you want it to, the key is to take as much speed into the corner (with control) vs diving in the corner, jumping on the brakes and fighting to get back onto the power in the corner exit, be smooth, sometimes it seems like you are going slower, but trust me ....... it works!!

Two events this year, i didnt have my usual car, ran with my AE111 bone stock, auto. ran pretty decent, i honestly had no complaints running the car in "2", did pretty well, my only concern was that Toyota's comfortable ride on the road translated to lots of sloppy body roll on the dex course, suspension was way to soft, shockingly i didnt really experience as much understeer as i thought i would..

If the body roll wasnt such a pain in the ass, i would much prefer use the corolla with a gearbox than the rx7 :|

The body roll is not as bad as some other cars, but here are a few tips youc an try:
as much as possible, brake in a straight line. As much as possible, trail brake to the apex. Do not punch it when you hit the apex.....get back on the accelerator just as gradually as you let off the brakes......

The fact that you minimised understeer means you are probably doing this already

The key as KIrk has always shown, is keeping up your momentum without overdriving the car

Also, you do not want to shift the weight of the car unnecessarily

Too much gas through a corner will shift the weight to the outside, and steal traction from the front wheels...similarly, if you apply too much brakes and have to release and reapply, the weight shifts back and forth front to rear, and upsets the car's balance...........

Driving in 2 works very well in the corolla. With good tyres it has lots of potential

^yeah, i was trying alot of what u said MG, actually more because of it "felt" faster and much more stable than other techniques i tried with that car..
had some pretty good tires as well. Michellin Pilots 205/50/R15
Braking in a str8 line actually i did because i had no choice lol, it was the only way i could have kept traction turning in at the top of the course (gravel issues :| ), late braking worked suprisingly well too, Wagner pads are impressive :idea: no brake fade, no glazing over etc...good stopping power, except when i tried braking really late, used up all the tires traction, couldnt steer and cleared away one section of the chicane...but that was just my haphazard driving :lol:

Tiptronic is nice on the road, not so nice for DEX. Very irritating to drive. Especially if the engine only begins pulling at around 5000 rpm, like the MIVEC.

I think a normal Auto transmission would be better.
