Default What happened here?

Ok so I did a log today on a map I have been running for about a week. I have no idea what happened, maybe some bad gas or something, but the logs from last week looked fine, today my logs look horrible. I did the log on the same road, the same way I always do for consistency.

Log from a week ago:

if it were bad gas, i'd expect it to be pinging all through the pull, not just during spoolup.

did you change anything on the car? are you sure there is nothing loose and banging around under the hood? all of a sudden, it adds 10 degrees of timing back in, which seems strange to me.

I havent changed anything, and I dont believe anything is banging around. I am going to check again today when I leave work. The only thing that has changed is I got gas the other day (same station as always) and I havent done a wot pull in about 5 days

was the car up to temp?

for whatever reason, I can get my car to register -2 to -4 knock around 2k RPM on the first logged pull. after that, I have no issues. I warm the car up completely (have oil pressure gauge which I let reach 90C) and the first time I roll into full throttle, it knocks.

I thought it was related to my trunkmounted SMC injection setup, like the alcohol wasn't reaching the nozzle after sitting a while, but I "purged" the line prior to my first pull, and it still knocked.

if you figure this out let me know what you find!
