Started doing autocross this year and having a blast. Now that I'm a bit better I'm more frequently getting to the top of 2nd gear at around 60mph. Was wondering if I should be shifting into 3rd earlier, and if so, how much earlier. 40mph in 3rd is about 3500rpms. My initial thoughts are to shift into 3rd around 40mph if I know I will hit close to 60. If I only reach 50mph just keep it in 2nd the whole time.

Wanted to hear from others with experience on how they shift.

Shift to third when the course gives you space to. But I wouldn't shift much below 50.

Honestly rowing the gears like a S2000 wasn’t too enjoyable for me, and took focus away from actually navigating the course. (Our local courses tend to be very tight, twisty, miata-bait so not a whole lot of time between significant elements. But I would definitely bounce the limiter without shifting. YMMV)

I flashed xHP stage 4, put it in S, and turn DSC all the way off and go. Works great for my level of driving.

If I had a MT then I wouldn't be asking since 2nd gear is longer and it's effort to shift. With the 8AT it takes no effort to shift but 2nd gear is shorter. I guess my question is more, what is the lowest RPMs that still has power. I guess an actual dyno graph would tell me that.

They said anything more than 2 on a non built transmission is looking at too much pressure and blowing the seals.
