Just did two Logs, Feedback Knock?

I did two different logs on two different days. I am looking at my Feedback Knock and getting a little scared. 7 is my first one and there is a difference in the logs when looking at the Feedback knock for 10. Should I just do another log to make sure its not me and not the car? Besides that does it look okay?

Thanks Chris.

It's pulling a decent amount of timing in the 5500 rpm at 2.2 load. That seems like real knock to me and the timing also looks a bit high, though your mods/tune info aren't listed.

Sorry. Just stage 1 AP V2. With a k&n air filter. But besides that bone stock. With 93 Oct map.

The main thing that has me worried is that under alot of load the numbers decrease which under my understanding it should stay the same the whole way through.

Well it knocked at around 5500 and pulled a couple degrees and that was enough so it pulled another 2 degrees. It might be safer to try the 91 octane map.

Okay cool. I will give that a try. But besides that does it look okay?

If you can post a log of a pull in 3rd gear from 2krpm to redline after you flash the 91 map. If there is no knock then that is a good start.

I wouldn't be so quick to call that knock yet. You started releasing the throttle at just about the same time you get knock. It can be "lift" knock.

 

Pull up to 6500 without letting off the throttle.

 

Also, remove "dynamic advance" and "maf volts" and "a/f learning" for now. It probably won't help a whole lot, but every bit of extra resolution counts.

 

Relog.

Is lift knock just as bad for a car? I've noticed that when I knock, it's either low-load/low RPM and when I lift off. Does this signify anything?

This might sound a little dumb, but does it matter if I still have some 93 oct in the tank when I flash over to 91 or should I just burn threw this tank and fill up with 91 oct then flash over. I have read on other sites that running 93 on 91 is a little more safe than just running 91oct.

If you're going to flash the 91 map the idea is to still run 93 for the additional security/safety.

 

It may or may not be shift related knock, but pulling 4 degrees of timing at 5500rpm and over 2 load would concern me.

Yah I am going to flash over and go log and see what is going on.

I'd relog to confirm prior to flashing but that's just my opinion. Do whatever you want.

 

I'd also try to get the AF learning trims read (the equivalent of a LV) prior to a reset, to see what your fuel trims are. You really need to do this to have an accurate picture of what's going on.

 

To pull an AP equivalent of an LV:

Hey so I changed over to 91 Oct map with 93 gas stage 1, These are the two logs I did. After doing this makes me think it might have just been lift knock now.

No way to tell for sure now since you reset and didn't pull any of the steps I suggested to you.

 

You have no idea what your fuel trims were. Maybe they were really negative and caused knock.

 

Whatever, you don't have knock now so don't concerned, for now.

I plan on switching back to 93, This is still all a learning curve for me. I do appreciate the links that you sent me they are very useful. I have been looking around at other peoples logs for a 05 model. Should I compare my log sheet to others log's or would that not make sense since no two cars are made the same.

Im sorry, but are you able to run K&N filter on OTS stage1 93? I thought the OP should be running a stock panel filter?

I am not suppose to just never got around to changing it out with a OEM one, also I am running a 91 oct map now not 93 but going to switch back to see if I am still knocking

The k&n will mess with your fuel trims and could cause knock. Best to switch it out.

 

My thoughts exactly. No point in the K&N, your probably losing power by using the OTS with it, and getting knock. Change back to stock filter, flash to 93 and have fun. Otherwise, you are taking a bit of risk. If you want to keep the K&N, then get an etune or protune. But by any means do not keep the K&N in with 93 Stage 1 Map.
