As far as why it shouldn't be active all the time, the GTR would be the case in point.
OK fine. I'll consider doing one run with my trusty PerformanceBox.
I have come to the opposite conclusion: Launch control doesn't belong on any car. It's merely the construct of spec-chasing automotive manufacturers and internet fanboys. Understanding a car's dynamics doesn't come from using a completely automated system to launch a car.

it's another torn issue imho. on one hand, getting some "numbers" seem to be the norm these days, if you don't do it, you fall off the comparison somewhat. that's the unfortunate part. but overall, i agree, i don't really care about launch control as much (even the ones in m3, etc...). the car overall and how it drives, that's what i am more interested in. plus for a car like this, how it does in straight line, it's small part of what i care
Please tell me your kidding! I think people that have money, & buy a supercar, but never drive it to it's full potential, even every once in a while. Are just plain LAME. Sorry if I offend you by this statement, but that would be your fault.

I'm going out on a limb and saying their best times will be 3.4 to 60mph with the LC, maybe 3.3 but I don't see any faster, not with the tires it comes standard with. Maybe the Nurb edition will have 'slicker' tires? I wonder though, isn't the Nurb edition just additional body parts, 10more HP, lighter (better IMO) wheels, stiffer suspension, and a fixed wing? Or does anyone know anything more? Maybe that's for another thread.
you definitely think wrong. most exotics sold actually never see the track or driven to even half of their potentials

I wonder if the new launch control is only going to benefit up to the current level of grip. Launching at 3700 rpm might be ideal for the current tires, but what if the owner decides to upgrade to a sticker tire? If would be really cool if the launch rpm could be customized by the driver.

The launch rpm is fixed at 4000 rpm. It does not appear to be modifiable by the driver.
The computer adjusts the clutch slippage and also the ignition timing to get the best traction while holding the rpms and not letting the car bog down. Therefore, it will dynamically adjust to the traction the tires are giving.
I am very opposed to the idea of Lexus not giving the LFA super slick tires. Most less extreme cars like GT2, Aston Martin V12 Vantage, LP570-4 etc. come with super slick track tires (PS cup tires, Pirelli Corsa).
Off the line traction has been the issue with the "neutral dump" technique and had been cited by every publication that tried it resulting in lower than normal times considering LFA prototypes highest recorded trap speed is between 125 mph (C&D)- 127 mph (Automobile Mag), which is good for low 11s.

Knowing how the computer system works, i would love to see the system customized. Knowing what the general focus on the LFA is, i dont find it hard to believe that someone would track the car with a DOT legal track tire.
The increase in grip is actually going to lower the trap speed along with the ET. I would love to see how the car does on a hoosier

Right from the beginning, I was very opposed to the idea of Lexus not giving the LFA super slick tires. Most less extreme cars like GT2, Aston Martin V12 Vantage, LP560-4 etc. come with super slick track tires (PS cup tires, Pirelli Corsa).
Nurburgring edition comes with super slick Bridgestone tires, though.

I don't take any offense from your post. However, I do feel quite sad that you have the beliefs that you do. I feel quite sad that you actually believe the "full potential" of a supercar only is reached when some silly automated launch control system is activated... and the LFA's engineers would feel sad too.
To be perfectly honest, I would have been more happy if launch control had been left off the LFA entirely.
