Monterey never gets that hot so limp mode really shouldn't be an issue even with a stock car. The real issue for long sessions with a 135 at MRLS seems to be the brakes more than anything else. That track eats street pads, even good ones. I believe Randy Pobst went 1:45 in a bone stock 135 around MRLS, so as you can see I have a lot of room to grow. He could probably be sub 1:40 in my car.
Contrary to other peoples experiences with limp mode I don't have that happen very often. The times I did have it happen it was due to the BMS intake I had on the car. I removed it and haven't had an issue since. I ran two days at Thunderhill two weeks ago with day time temps at 110 degrees without having limp mode raise its head. I do have a FMIC and oil coolers so those help tremendously. For comparison in the open group at Thunderhill Spec Miatas run in the 2:11-2:14 range. My 135 will run 2:08 lap after lap without limp mode, brake fade, etc.. The key might be that I only have a slight tune on the motor, guys with other tunes seem to have a lot more issues. Just a thought I'm not sure though.
I run in the open group and I have a bit of experience so that definitely helps keep my times down, but I'm not a pro. If you learn where to push and what the car is doing underneath you, fast times are readily available in a 1 series. Brakes, cooling, tires, and suspension all need to be addressed in order to be fast. For the money I've spent I could have made another car even faster, but the 1 series does double duty pretty well and this is still a car my wife drives to work every now and then so it can't be a total track rat.

Well that is legitimate. Thank you. This helps other 135 owners to know what works based on fast driving.
I was T-hill 2 weeks ago in 110 degree heat with NCRC. Is that who you were with? I was in my daily driver white 328 as my track car was broken.
I'm amazed with only oil coolers, and an FMIC you don't have limp problems.
