Track day report.........oops
I would definitely take your car to the dealer after watching your video. That kind of driving shouldn't have any effect on the engine or other components.

The Boss was fantastic at the track. I was able to get some instruction in a Miller Racing Mustang by the fellow that runs Hooked On Driving in my area. Best instruction I've ever had. I got back in my car and drove the wheels off.
The oops(1): after 4-5 sessions, the Check Engine Light came on. I ignored it. Then, right at the end of another lap, the CEL was blinking and the engine went into limp mode. I dove for the pits so I wouldn't have to be towed. After the engine rested, all was fine. The engine coolant never went past the middle of the gauge.
I'll be taking it in on Monday for service. My service rep suspects the throttle body lost signal, since there was no overheating.
Oops(2): on the way home a car in front of me ran over a piece of trim and launched it at my left front corner. It dinged my hood's edge and scratched the headlamp. Oh well, first ding.
Incidentally, I ended up reducing the tire pressure by 7psi after the first couple of sessions to keep the stock tires at 41psi.

Ok this is no longer an isolated incident. Did the CEL clear or do you still have it? If it's still there I am betting on a P0300 random misfire. I've thrown that code on every one of my four track days. The time prior to this last track day the Hotline had them reflash my PCM but I still threw the code however never went into limp mode. I have had the flashing CEL accompanied with limp mode on two separate occasions and both times it cleared itself and the CEL. When I get the P0300, I have just cleared it myself. Ford needs to figure this one out.
I'm glad you had the same reaction to the Boss as I've had on track Dave. It is an awesome track car.

Please message me with your mileage, dealer, VIN, and contact info. I would like to escalate this info for you.

The coyote engine is know to over heat the oil on the track, that's why the Boss got an oil cooler in the first place.
The dealer should be able to read any pass codes even if the light has gone out. Let us know what it was. Thanks.

Doesn't look like it's real high speed in the straights but some very fast fun corners.

I've never been there but Thunder Hill will likely be the first track I drive my Boss on. I didn't realize it has a mini corkscrew!

I did throw in a bottle of Water Wetter yesterday and am planning on doing the grille mod. It's only going to be in the low 70s this weekend at BIR so not worried about getting it done this week. Hopefully when I get back. Maybe one of you other guys will guinea pig that mod

You know I thought the same thing. However, when I took mine in on the occasion where the CEL cleared itself, they couldn't find anything. I couldn't find a DTC on my Aeroforce gauge, but figured the dealer's software would still find it. Nope, not there.

Same engine, different radiator, oil pan (there's is 12 qts), a different oil cooler setup, and a different cpu program. It's very possible that the oil is getting too hot and causing the cylinder temps to rise to the point of throwing the car into limp mode to save the engine. Oil temps and water temps can differ by a significant amount with extended hi rpm use. It's my opinion that an oil temp gauge (and oil pressure) is a must for any track driven car.

I have run the car hard, I assume not as hard as Dave or Gary but I have not babied it and have no issues. I wonder if taking off the plastic cover under the engine will help (the one that you take off for oil changes). I have not see anything written on this, what do you guys think?
That is strange, I have never seen a code erase itself like that. I think after many miles (thousands) or a 15 min battery disconnect it will but the only other way it should clear is with a scanner tool.

Good points raised about the oil temps...it will be interesting to see if you can get the dealer to give you any data.

My oops moment. Nasty rasp beneath and forward of drivers side door developed at 4500 rpm in 4th gear when pulling past 120 KPH. Developed during right turn acceleration. Something's loose as it seems to be a harmonic vibration. On a side note Douglas Ford from Barrie were running a 3 day old delivered Leguna Seca edition at Mosport today. Nice! Mine's already got over 4600 KM on it.

Yep that's what I'm thinking. Already have bank (read spouse) approval for it, but wanted to see someone else guinea pig that one. Sounds like a couple guys have theirs in transit. My ONLY hesitation right now is having a better understanding of what rain will/won't do when getting into the engine bay through the vents. It's not like I make it a practice of running in the rain, but I also daily drive my Mustangs and have an open trailer so it's going to occasionally get rained on.

Gary, What were they using to check the code with? A universal scan tool like a Snap-On or a Ford diagnostics computer?
