Check engine light at track
Comes only when going hard. Could be corner related. Doesn't affect performance at all and goes away immediately after turning car off so I can't check the code..
I'm thinking either o2 sensor not happy at 8000 rpm, knock sensor? Could an oil starvation cause it (oil looked fine anyway). I started putting a sticker over it cause ****s with my mind mid lap :P
Any ideas?

It's a b18c2 with a p72? (The stock one, correct me if I'm wrong).
It's definitely coming on at high rpm but not definitely from vtec as some sessions it wouldn't come on but pretty sure vtec was engaging every lap. So seems random but related to hard driving.
Someone at the track suggested o2 sensor if the tune was out at high rpm but I don't know if ecu cares about that.
