Anyone want to have a look at one of my logs?

A few notes:

My car is basically stock with a MBC, keydiver chip, and my ECU is jdm so unfortunately it doesn't show fuel trims. i just want to know if everything looks normal, I only did a short wot pull (around line 886).

A couple quick questions:

At the end of the log i idled for a bit. Is it normal for the idle to fluctuate from 812 to 844 and 875? I did the procedure to set the base idle but it still moves around a little like that.

why do i seem to be getting a ton of knock (winds up my knocksum gauge) when i turn left or right sometimes? it doesn't seem to happen otherwise.

thanks! /ubbthreads/images/graemlins/cool.gif

The idle fluctuation is normal and How old is your knock sensor?
What condition are your motor mounts in? Mainly the timing belt side one?

Your o2 sensor appears to be pegged lean. That's strange since you got up into the 75% IDC range with zero knock. I'd look into replacing it.

Edit: NM. I was looking at o2-F which doesn't exist. o2-R seems to cycle normally so I'd say you're good to go.
