Thanks. Yeah I'm connected to the Porsche Specific one. I was told this one but can't log brake pressure. Is this the one you're using? See below:

Yeah I found that as well. But I'm. more concerned with the analysis rather than the video. It'll be nice if I can compare braking (both timing and pressure).

Do you have a manual transmission or PDK? As I mentioned, if you have manual transmission you cannot get brake pressure through obd2

Great driving Joe! We really enjoyed watching you thrash our brakes. I'm also glad you're liking the new Ferodo DS3.12 pads. I just put them on my C6 track car yesterday, and they are indeed awesome. What was totally weird is that they are completely silent on my car...not a single squeak, chirp, or squeal!

Forgot to mention: don't let the fuel gauge even touch the red 'E' zone. You will get fuel surge through T7 and T8 in this car. In prior cars I would be able to drive deeper into the E zone before it happened, but in this car, as soon as the needle touches it, you will get fuel surge and go into limp mode if you are at full tilt through T7 and T8

Wow, good to know. Was the .1 GT3 (and .2 regular GT3) any different?

I recall fuel surge on the .1 as well, but with even less gas in the tank. I only had the .2gt3 at thill once and didn't let the tank go low enough.

T7 and T8-9 are super G corners, and super high speed. Totally worst place for a stumble...could get rear ended if it happens at wrong time with wrong person behind!!

Good to see one's own initial impressions about Dunlops confirmed by someone who does more running.
Experienced the same thing with fuel on the exit of Pouhon at Spa.
Low fuel helps the laptimes but stutters in the middle of fast corners can be an unpleasant surprise.

When it goes in limp mode, do you also lose all even gears?

On my 991.1RS with 90L tank, losing gears only happend to me once and all OK after filling up the car.
Usually it goes just in limo mode. I’ve sent video of it to Andreas Preuninger after explaining it to him at Goodwood as I think it can be dangerous. Seems that instead of fixing it, it became worse?

On track I try to never run it below 30 Miles to empty, or about a quarterone tank.
Street driving I flat line it all the time, no problem.
