Have yet to wire in my wideband, figured I'd do a pull to see what the car is doing stock. It's at 22:34. Had a bit of knock in 1st, didn't rev the **** out of it, timing stayed below 20 degrees of timing while on the throttle hard. Anything painfully wrong looking at this? I ordered the master efi tuner book, probably won't change much till I put headers, y-pipe etc on.

EDIT:looked at the histogram, appears the car is using the low octane table? Running 93

Once it detects knock the pcm uses the low octane table.

I've read it takes a lot of knock to get it to switch and takes forever to come back out.

Car of course runs much better now that it's back in high octane table.
