I wanted to know if anybody here could review my datalogs. The two most recent ones that I have consist of my drive to and from work. I tried to hit wot a couple times but unfortunately the traffic wasn't permitting. I believe I was able to open it up briefly maybe once or twice each way. Mind you I have about a 45 minute trip there and back so the file is large. On both drives I noticed the feedback knock sensor read -4 something and -5.60. If I remember correctly, in both instances I was in low throttle. The 4 something I heard a nut or screw drop from when I was putting the stock airbox back in. I may have run over a plastic container. Idk. Both were there and gone fairly quickly and only happened once, phantom knock perhaps. I am concerned about my engines health and am trying to get in touch with Precision tuning here in NJ to set up an appt for a protune. Worst case I will have to just swing by. If anybody can give this a better read I would greatly appreciate it.

christ. I took a look at them and its like 225 pages long. So that isnt going to work. Ill be sure to do some short pulls later on tonight when I go back to work. Apologies.

[ShunGokuSatsu]

update. i managed to get 2 or 3 pulls in last night on my way to work. unfortunately I wasnt able to get too too far into it, due to traffic. if somebody could look at these and tell me if they see anything I should take notice to id appreciate it. thanks in advance

First, your logs are stupid long lol! Second, should turn on AFR sens 1 instead of afr learn, show us what your afr's are during the pull. Lastly, you're going wot at 4700 rpm, should try to start around 2500-3000 rpm and finish around 6-6500 rpm.

 

I see the knock you're talking about, I would think its phantom knock ,but it's hard to tell though as you're only doing partial pulls. Sorry that's all I can help with..

I'm running a lwg map. If I open it up at 2500 or 3 it has a tendency to spike. With the af1 learn, it reads 11.14, going by what you're saying that isn't quite accurate. I was under the impression that because that's the limit of the stock o2, it's running leaner than that.

The A/F sensor that parameter pulls from isn't going to show anything bellow 11.1. Try to get a WOT log from 3k-6k. The few knock situations you had were right after the throttle position changed so its hard to say what the sensor was picking up.

 

A mod list would also help, and if you want to get accurate AFR readings pick up a wideband.

The mod list so far is a GrimmSpeed divorced downpipe, invidia q300 cat back, and Cobbs stage 2 lwg duty map. Im going to be swinging by precision tuning tomorrow.. So on my trip I'll get you a log. I've noticed that when I hit a good bump I'll see the knock jump up a bit. It seems to very sensitive. That being said, the heat shielding on my UP rattles and id like to think it's just that. Every time I get a blip it's been at low throttle. When I've opened it up I haven't seen a knock reading at all.

did a third gear pull =\

So what did precision tuning say?

They suggest that I upgrade fuel pump, injectors, and run an external wg prior to tuning.

Fix that heat shield and tighten anything else that may be contributing to the FKL. Also, your boost curve looks like a rollercoaster , hopefully you can get that straightened out soon:).

[Grothe08LGT]

So how is everything looking now?? Get that noise figured out? Curious to see what was the cause of the noise you're picking up.

I put the stock airbox back on. That helped a lot. Have an UP and ewg coming in soon. Then a protune. I see about 2.45 or 2.80 when the same load is applied. DAM is still at 1 so that's good. But besides that it's been running decent. Rich of course, but decent.
