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!
