L99 (best mode for racing?)
 

What's the best transmission mode for drag racing?

I would like to hear from the guys that are running good times what computer transmission mode you're using.

1. D - (regular drive)
2. M - (sport mode)
3. M- (sport mode using paddle shifters)
4. Competitive mode (8-37 in the owners manual) -press TCS button two times quickly.

Thanks.

Tried each and every one of those combos last night... wish I had time to complile all the numbers... maybe this evening...

The winner was S Mode... Competitive Mode... No paddle shifters :thumbsup: although others like to have everything off.

Reasons were with T/C off I got wheel spin once off the line and another time using tap shift from 1st to 2nd. When I had T/C off and got no wheel spin I ran the exact same time as with T/C on. (so I prefer to be safe and leave it on - comp mode)

Tap shift will take lots of practice becuse it's soooo slow to react. You have to anticipate the tap so it can really screw up a a good run (but save your motor...:D) I gained nothing using it during a perfect run except for a chance to shift late and lose time.

One more note... it's easier to have everything off when coming to the line... That way you can do a burnout and just pull up to the line rather than stop to double tap back to comp mode. I still prefer Comp mode

what is the difference between competitive mode and sport mode(not using shifters)

Sport mode is a gear selection option (D, S, or M are available).
Competitive Mode is a tractio/stability control option which turns traction off and leave stability on.

So how do I get it to stay in 1st or 2nd gear to take it up to 3 or 4000 rpm and let it back down, it shift's on me?

Actually traction is still on but will let the car spin a little more than with out.

You have to use the paddle shifters to keep the car in a gear. They are on the back of the steering wheel.

When you put the shifter in M(sport mode) it will shift by itself. Once you put the shifter in M(sport mode), click the + paddle and you are then in control of shifting the transmission.

I think that's what you're asking:iono:

I would also like to add, once you touch the tap shifters in M- Sport mode (it switches you over to manual mode). You must now shift the car yourself until you move the shifter back up to D (regular drive).

When I'm done using the paddle shifters, I move the shifter quickly up to D and then back to M (Sport mode). I pretty much use M (Sport mode) for most of my daily driving. I rarely use the paddle shifters. But sometimes the paddel shifters are fun to play with. I also like using the paddle shifters when I want to hold first gear when rolling slowly off the line.

And make sure you time the shifts properly when using the paddle shifters. There's a slight delay on the shifts so you can end up hitting the fuel cut off/redline if you're not paying close attention to your rpms.

[QUOTE=SGOS252382;706303]What do you gain by driving in sport mode?

[QUOTE=NativeTexan;709221]
Sport mode holds each gear a little longer (higher rpms). It also seems to shift faster. It's basically a more aggressive setting for the transmission.

But to be honest, I'm not sure how much faster it makes the car run
(0-60mph, 1/4 mile), but it definately makes the car feel faster.

Does it make a difference with the fuel efficency for daily driving?

When I use M (Sport Mode) the engine seems to stay in each gear to a higher rpm before upshifting (even at part throttle). So I would assume that would slightly decrease mpg. But I haven't done any actual mileage testing.

Thanks for the info. I am planning on running on a local track next Friday. I am itching to see what she will do.

Have fun, but Texas in the summer can be tuff on track times. I know some guys with late model GTO's that live in the Dallas area and they run pretty slow times this time of year.
