No, I just listen to what the car wants and not what "I think it should do". Haha. I have heard that from a few guys now that their tuner said the car "should" do this and it has a knock issue like yours. All I can do is go by your datalogs and what we see, I don't tune based on what I think a car ...

Hey EFICU I apologize for the delayed response. I have been on the past tune you have sent me and did need to make a road trip with about 4 hours of driving with plenty of pulls and did not get a single knock. A/F seemed to be pretty consistent across the rpm range as well.

I was able to log the ...

Okay, interesting, it's not as bad as I thought it might be at part throttle driving so that is good. It's actually just fine honestly.

Yeah the knock is in one of the two places where we had the other knock. And two of these knock were in 5th gear pulls, which is about as much stress as you can ...

Sorry about that! Here it is!

Okay, I figured he must be using a wideband then for tuning for it to be that rich through the primary sensor reading. Hard to believe they are that much different, but it's possible. The richness should not cause the knock, if anything it would help reduce it. But if he tuned it for the wideband ...

So both tuners had the same issue at the same RPM?

Was the tune in this datalog done with a wideband in the stream at all or in the tailpipe? The AFR is in the 11.80’s which is more for boosted setups, 12.8-13.0 is more for NA. Just curious why they tuned it so rich.


First tuner i was getting ...

So we have pulled timing out of the top end. Did seem to due the trick. Did a few pulls with only one knock. Although the the next day i had a 1,2,3 count at 5500 and then its been consistently knocking ever since. I am assuming IAT effected it.

thank you for the reply just posted. sorry new to forums

Desperate for help at this point!!!

I have a 2015 9th gen with a stock k24. Skunk 2 CAI and rear hasport motor mount.
I am getting knocks from 5500-6000rpm mostly from 3rd gear and above.
I have had this issue since last year when going through with an etune and have then had the car dyno tuned ...
