New knock sensor new log safe afr low boost still timing pull !

[v8killer]

hey guys i put a new knock sensor on because i was getting random timing pull. well first log i had no timing pull at 14 lbs turned it up to 16 lbs and i'm getting some timing pull !

stock 2g timing curve, afr 10.6 through the run from what i could see !

does it look like i'm pulling timing when i first get into boost then it try's to recover through the rest of the run ?


time rpm timing
61 2784 23
61 2860 18.5
62 3024 13.5
63 3232 10
64 3536 4
64 3904 5
65 4240 7.5
66 4636 8.5
67 5032 9

i posted a copy of the log which was rpm and timing advance. which you can see is low through the pull compared to the stock timing curve which peaks @ 16 deg !

We can see the timing going up and down that's not the problem. We cant see whats causing it. If you are looking for us to guess that's different but i would rather have a log so at least it will be an educated one.

well what sucks is i can only log 2 things at once till i get my new cable and other logging program working ! i'm hoping its just rich knock when it comes into boost ! going to try and lean it out when boost comes in.
