You definitely want to cool the brakes before coming in. Last lap should be slow enough to not touch the brakes. The ting ting sound will become a loud crack eventually of you don't.

yea, going really pay attention to the tire temps next time out. what PSI do you run hot? 32?
yea, normally i certainly do run 1-2 laps cooldown, but when your car is going into limp mode and you can't go > 50 mph and 3800 RPM, you can be a danger on the track, so i would come off and drive around the back parking lot for 5 min, lol. i noticed the pinging just when i stopped in the hot pit to let out pressure, but now i realized, maybe i should have done a cool down lap before even hot pitting.
also first time out with a big heavy car with tons of power, so was also just getting used to these new track behaviors. should be a lot better 2nd time around, and hopefully no turbos blow up. |

If you keep getting limp mode you should read the codes to figure out why. Probably still there as a stored code. |
i pulled the codes at the track. boost related, bmw literally replaced one of my turbos… |
Well fuck me…glad its fixed
