Hey everyone,

I've been keeping track of different information that comes through my obd2 reader. One of the things i've been looking at is spark advance. Typically i'm at 17-26 while driving (average is probably 20-22, but it drops down to 12-13 at idle.

Is this something i should be keeping an eye on? Or is it something without any value that i should ignore....

LTFT is usually 6-7 at idle but it goes down to near zero while driving. I did a smoke test for vac leaks and nothing at all...

Thanks!

I wouldn't bother monitoring spark advance. LTFT's will change depending on engine rpm and load along with a long list of other factors.
