I noticed that recently when boosting (16psi), in 2nd or third around 5-6k, the CEL comes on. I pulled codes, but I get a code zero. I know my ECU is bad, it just sits there to control idle and A/C, my standalone controls the rest.

Do you think the CEL would be a knock up higher in the power band? I was only running 91 in the car (it was winter, and I wasn't boosting). I'll try some 94 and see if it goes away, but I'm curious as to what the CEL was.

I may have to plug in some headphones to my knock amp, and do some investigation.
