Nice initial read/reaction, but really a great illustration of the GT3's systems at work. By the time you fully steer into the slide they're already shutting the whole thing down, prohibiting a tank slapper.

 

The vbox data wasn't reading the CAN bus, so you can't really go by what on the lower display.
Not saying you aren't correct, but I need to pull the data from the track precision app to see the real data.

 

You are correct.

 

So, I was able to view the video on my office computer. I definitely hit something. You can see the left front of the car bounce at the beginning of second 11 on the video. You can also hear the vibration.
I can't see what it was, but I was enough on the limit that it wouldn't have taken much.

 

What do you mean, you're not sure if the systems were intervening?

 

I'm sure they were doing something, but the data you see on the display isn't live data. That's all.

 

Yes this is textbook ESC intervention. Not taking anything away from you as a driver or suggesting inputs weren't correct, or didn't help, but the GT3's systems are physics defying and one step ahead.

Let's say you experienced the same event in a 997 Cup, highly unlikely the time & inputs from sideways at 91 to calmly straight ahead at 60 are the same.

Believe we were just exchanging on the TC & ESC system benefits the other day. This is exhibit A on why they should stay on unless you have really good reasons to turn off.

 

Ah, gotcha. Yeah, I'll take all the help I can get from ESC/TC. I may have mentioned that I only turn them off for maybe one lap when I am trying to diagnose an alignment setup issue, and I definitely dial things back when doing that.

I wish the VBOX was working properly, it would at least show when the ESC systems intervened.

 

It's apparent in the yaw control and lack of drama from the moment you steer into the slide until calmly straight ahead at 60. Believe you may actually be able to hear the variable braking being forcefully applied from about 0:12 - 0:14.

 

I don't really like to give opinions based on videos, but honestly this was a small oopsie daisy, kind of stuff that happens pretty regularly when pushing, or cold tires, or worn tires, or whatever.

I've done multiple four wheel slides in the carousel when racing WRL in a GT4 Clubsport with street tires, usually carrying too much speed on the wrong line passing someone. Street tires are more prone to that than slicks in my experience.

You caught it quickly, unclenched sphincter, and went on your way.

From the little I can tell the nannies might have assisted you in avoiding ye old tank slapper more than the original skid which you caught yourself and might have slightly overcorrected. Hard to tell without all the data plotted over the video.

It's all good, keep pushing.

 

Agreed, frankly I was more annoyed with the wipers.

I just wanted to share to show that stuff like this happens pretty frequently - not that this was a big "oh damn" moment.

I'm not perfect and wanted to show some of the mistakes with the good stuff.

Thanks for your comments. They are well taken!

Were you recording with the track precision app? It shows when esc and traction control blip on. The feeling when esc steps in hard is like someone has attached a cable to a corner of the car and yanking on it. If it’s a front wheel you can feel it through the steering. With the mods you have with suspension, brakes and tire ratios, I’m surprised esc even works correctly. On the 981 gt4 it was very temperamental at high g forces (Hoosiers) - to the point that it was useless and intrusive.

 

Behind the wheel footage ESC off vs. on. COTA slide and correction parallel the latter, with clear system intervention. 992 GT3 ESC light years ahead of this old Lambo ESP tech.

Cool that the video was shared and informative to deciding what traction mode to run in GT3's. Porsche nannies are brilliant.

 

looking at the telemetry the driver's rear tire what starting to shift weight to the front at 10s just as you were hitting max cornering g's . Would have certainly been a spin +/- weeds without the deft nannies. I have a video of a GTR doing something similar at TWS on T13 CCW at 6:06 mark in my first signature video, but nowhere near 1.15 lat g's lol... You were flying there buddy!

 

agree, this is why I suspected this as above. in my 992 GT3 it is very sudden and jolting if/when it intervenes
