I have a 16 s awd and now that it’s colder, I’m more inclined to play, the issue is... it’s crap.

i engage the brake, press the gas down and once it crosses ~1,200 rpm it will say launch co trip active.

the issue is that once it hits right past 2k, if I keep it there for what seems like any longer than 1 second, it dumps the rom range down to idle again quickly and the car takes off slower than a snail on a glue surface.

do these cars not have launch co trip like the 2 step cars or my old Porsche?

Is is there a way to make it better?

 

The functionality is different. You're supposed to hold the throttle at the point where you get the activation message, not floor it like some launch modes on different makes.

 

So you’re saying it’ll launch the same weather we launch at 1,200 or 2,500 rpm?

 

Quick demo at 55 sec in....

 

That's not what he was saying. He was saying don't just floor it, you have to actively hold the RPM properly.

 

and im saying any rpm above 2,500 won’t work and anything above 2,000 gets disengaged too quickly to hold it anywhere

 

My assumption is the vehicle is doing that on purpose to protect itself. These cars aren't like the hard launching Porsches and GTRs of the world you might expect. In the higher horsepower R variant; launching off idle is the quickest way to accelerate. Anything beyond that the car torque limits to protect the transmission and you go slower.

 

wish the V8S RWD had launch control.

 

Again, it wouldn't do anything. Launching off idle is the quickest way to go. Effectively you already have launch control...

 

I can remember the good-old-days when a driver would simply get the revs up over 5K and then simply side-step the clutch...then the driver became the launch control!

 

You do that now a days and you'll be buying a new transmission.

 

+1. That's why they have a clutch delay valve and a dual-mass flywheel on the MT cars. No need for side-stepping with a tuned V6. You can light up the tires at will with the clutch fully engaged.

 

Hold it wherever you get the notification. Then release the brake and floor it simultaneously.

 

I apparently just picked up an 2/16 manufactured '17 R but launch control does not appear to work. Even after following directions in Dynamic mode I never see ANY of the launch messages in the dash no matter how "gently" I push the accelerator down. Have others experienced this issue? I assume a software patch would resolve but don't know where to look in the system to determine which version I currently have loaded

 

I
believe only the V6S ever had launch control. The R has enough torque at idle not to require a high rev torque converter stall speed.

 

As usual, Lance is 100% correct. Maybe even 1000%.

You're not missing much. It isn't a 'smart' launch control that manages throttle, etc. It is fun on occasion, though.

 

ah-ha!
Makes sense. I was not paying a lot of attention of the cars in the you tube videos were v8s or not but now that you mention it, they were all v6s. I did see it in the manual but I expect that the manual's are identical for both engines. Just a bit odd that JLR didn't put some type of disclaimer in the fine print of the manual stating that it's only applicable for the v6s

 

Yes, the operating manuals describe all features and do not indicate which models have what. It confuses a lot of people.

 

Just bumping this thread in hopes we don't get a 3rd thread titled Launch Control.
