Had my second track session last Sunday at Grandsport Speedway in Hitchcock, TX. Previous outing was a novice training session so this was the first time I was able to run it hard. Grandsport is a short, tight track; 1.1 miles with 9 turns, top speed ~90mph. I did 64 laps over 5 sessions and on the last session the CEL came on. No limp mode, normal temperature, engine running fine. I checked the oil and all other fluids after the session and everything was fine. I drove home (40 miles) and with no problems. Took the car out for a short spin last night and CEL still lit. Got up this morning to drop off the car at my local performance shop to have him pull the code, and no light - it had cleared.
I couldn't find the thread but I know there is one with people reporting random codes being thrown during track use. I am curious if anyone had them clear on their own, what was the cause of the code.
I appreciate any input.

The code should still be available in the history. May want to stop by and have it pulled just to know what the computer was complaining about.

Thanks. I thought of that after I submitted that post. I will do that so if it happens again I will know what or what not to worry about.

Patrick, don't worry too much about it. It may have been the P0300 random misfire code. If it is gone now no big deal, if it happens again someone at the track should have a code reader you can use.

Thanks Scott. I now remember reading about that code some of yall were getting but couldnt find that thread.

P0666 - "I was at a track and my warranty is void code."

It goes off since it realizes it's not at the track anymore.

Rumor had it that the new ECU was smart but I had no idea.

HAHAHA!
No problem as long as I dont get the code:
P0911 - "Call emergency services, I am upside down in the grass!"

Hopefully the days of P0300 are behind us now that TK is out. You Southerners will have to let us know. Hoosiers and tire chains don't mix.

I am not going to be shy around the corners tomorrow! Maybe I will even misplace a cone or two again
