Alright, just got back from making some recorded runs on the streets...
Started with 5-min of idle, then about 5 min of open-street driving, and then a regular highway drive (3-5 min). Decided that wasn't enough fun, so made 3 WOT runs, pretty much hot-lapping them, and the 3rd got a little back/mis-fire going on. I looked over the last run a couple times, and I got 7 degrees of knock at it's worst point - gas??? (91 CA)
Don't wanna deal with trying to upload them now, if I can - but can someone take a look at these log files for me and let me know what I'm dealing with? If I can post them in the morning, I'll email them.
I'm hitting the sack...
