New Launch Mode - firmware 2.9.40

[NSX1992]

I had my battery heated while charging at the Supercharger and after that the battery was being heated without having to drive around. Because the dragstrip was busy I had to wait one hour between runs and yes the % went down with time but not as much if you were driving around. I did not notice any slip as the track was sticky. I believe you have 4 seconds after you initiate launch to press the accelerator down and then you must release the brake within 4 seconds to launch.

and to be perfectly clear on the sequence for those trying this out-

.stopped with wheels perfectly straight
.press brake with left foot hard and hold down hard
.quickly and smoothly cycle the accelerator pedal all the way to the floor and release using your right foot (while continuing to hold the brake firmly down with your left)
You should see launch mode enabled on your dash (not center screen)
.press accelerator to the floor with your right foot and hold it there
You should feel the car squeak and groan a little bit as the motors "load up" against the drive line
.side step the brake within four seconds and the car will launch else it will timeout and disengage launch mode

Don't forget "enable Max Battery Power" first and foremost!

And the ambient temperature must be above some arbitrary value (37 degrees F?)

Yes. Seems like the standard temperature where you get a black ice warning.

I noticed there's two different time-outs while holding the brake for Launch Mode. After you first press and release the accelerator, the "Launch Mode Enabled" message comes on and stays on for 10 seconds. If you depress the accelerator the second time before the 10 seconds expire, it will stay on and the car will squat for 4 seconds. If the 10 seconds expires before you depress the accelerator the second time, you'll get the "Both Pedals Pressed" message and no launch mode.

You've hit traction control, if it wasn't obvious.

Yes

 

[XxMFxX]

Yes

thank you

also checked today in my car and it worked

 

[silverp85+]

it would be a shame if this was not added to the p85+ or any p85 for that matter because they need it badly.

 

[joaquinsfy]

Yes.. Please....

I went to the 1/4 mile dragstrip in Fontana, CA yesterday and alternated every run (8 total) between Launch mode on and off. There were no differences between the two except I get much better reaction times by just pressing the accelerator quickly. But my best time was the first run with launch mode but probably because the battery was at its highest level of charge.

 

[lolachampcar]

Several have done back to back multiple runs with data and it shows no difference between fast foot and Launch Mode.

 

[AWDtsla]

Still waiting for someone else to repro but slip start with fast foot seems the fastest for me. You can't use slip start with launch mode.

 

[Dbitter1]

Also, at the risk of sounding waaaaay too obvious, make sure your car is not in Hill Hold when you launch if you are not using launch mode.

 

[edwardyork]

Yes. 7.1 includes launch mode for Yarkoweb PnDs if you didn't have it before.

Didn't have it before, now have 7.1 but launch mode is not included, it's not as if we could use it before Spring.
