kr always in same spot.

[zacknhs]

ok as i look threw all of the scans i have i notice that i get kr most of the time in the same spot. it's between 65-74mph and 3500-4000 rpm. i'll upload a scan from yesterday that has kr all over the place. i have been trying to tune the maf again since i tuned it with a hole in between the maf and tb.(opps)

i don't have a w/b so I'm trying to tune by the ltft's
i looked at the PE vs rpm table and i see there is a big step in the stock tune about where i see the kr all the time so i highlighted it and smoothed it once. i loaded it in and drove home from work last night that is the second scan.

can you post a bin file? im wondering if the lq4 is tuned wrong.

That is very normal KR. Your could desensitize the knock sensor to prevent false knock. All the SC V6 cars that I've tuned are very rich,
after I set the AFR to 11.5, the max spark timing is usually ~ 12* @ WOT. You may have PE spark, this table has been added to 2.1.19.
I zero out this table on my tunes.

I would be curious to see the bin as well to see what is going on in there.

here guys sorry i haven't been on here in a wile summer school sucks.

here is my last scan and htp file and i did desensitize the knock sensors by about half.
