1G Second Opinion on My Log

[LastPANIC]

Hi Everyone,
I wasn't sure on where to post this and I saw the Newbie Fourms (looked pretty accurate) My apologies if i was wrong.
Ill get down to business, So I have been having this Knock problem for quite some time now. Before and after the rebuild of my engine. In the higher Rpms 4-6k ill notice Some degrees of knock ranging from 0.4-8.1 I haven't determined if it is Phantom Knock or real knock and I would like a second opinion please
Note: I have it set up in ECM Link to ignore Knock Until 50% throttle and 3500 RPMS
Listed below is a small build list:

Bolt Ons:
340 Areo Fuel Pump (Rewired with 10g)
1250cc FIC injectors
AEM WideBand
14b Turbo
Hallman Boost Controller (turned all the way down)
Fuel Lab AFPR (set to 43.0 psi)
FMIC (Boost leak Tested up to 28 Psi)
3in Megan Racing Exhuast

Engine:
Manley H Beam Rods
Wiseco Forged 9:1 Pistons .20 over
MLS HeadGasket
ARP Head Bolts
Stock Crank
Stock Head

Tuning:
ECM Link V3

I'm wondering if that's rich knock as your wideband is reading about 10.3.

 

[LastPANIC]

Iv also tried 11.1 maybe i just haven't found that sweet spot yet?

Which MAF are you running?

 

[AWD-Tony]

You have evo 8/3g MAF selected. When knock starts, it THINKS you're at 7k rpms when in reality you're at 5k. I don't know why the rpm signal jumps at that point.

 

[AWD-Tony]

MAF slider needs work also.

 

[Vegas Smith]

It could be those high compression pistons you have? Maybe the car wants less boost because of that. I'm not sure sure. You aren't running a lot of timing so that's good. Do the usual checks for the knock sensor such as verifying correct location and if it's going bad (black goo starts melting)

Here is what a really bad knock sensor looks like. It came out of my 92 talon. You don't want one that looks anywhere close to this. It should have a smooth black finish of plastic/rubber and you shouldn't be able to see inside it.
Just an example.

correct I'm using the evo maf and i did notice that spike? but in other logs i still get the same knock without the sparatic jump in rpms so i ruled that out

appreciate the pic iv never seen a knock sensor that far gone 0_0 but mine is in the stock location and is fairly new still looks good

MAF slider needs work also.

could you go alittle more in depth. I'm still new to the tuning world.. thank you

 

[EVLGSX]

you want your WBfactor as close to 0 through the pull as you can get it. make the maf comp adjustments according to what wbfator tells you for the givin Maf frequecy. Example- wbfactor -4.5% @ 1200hz/ remove 4.5% at 1200 hz in the maf comp table

over time if you keep doing this, you will get it dialed in better, takes time but worth the effort. Closer to 0 seems to = less knock for me

16 is alot for your TPS adjust too, I wouldnt be happy with that. spend some time there getting that setup. Ton of info on that here.

Track the datalog while you pan through your log so you can see the cells its in when the knock is beginning/peaking/tailingoff and pull a few degrees to see if that cleans it up through those areas

I also noticed around 5k 7degrees timing (cell it hit)your rpms jumped to 7k 15 degrees timing (cell it hit) and back to 5k which is just bonkers

too much timing everywhere for where your at with this car though..........at least I think so given the situation your in.

Here's a great video

Adjust your MAF slider and post another log afterwards. As Vegas mentioned, it could be rich knock. I'd also like to see if it still reads 7k rpm instead of 5k. If you track your timing table along the pull, it does jump to the 7k/15 degree cell and that's exactly where the knock starts.

Post a full log. Warming up and WOT 3rd gear pull

ill see if i can get a better pull today but this is one i did yesterday

 

[AWD-Tony]

Looks better with almost no knock. What's with the title "random pull i found"

I was doing some driving just collecting data the log was probably an hour long and I did a few pulls out of habit forgot about it till i looked back over the log haha but its a hit or miss sometimes i can have a great pull and the next one i do i have knock? could this be an electrical issue?

 

[AWD-Tony]

I get that also. it’s weird and I don’t think it’s electrical in my case since the sensor is new. I’m still dialing in my maf but haven’t been able to since I’m waiting for an alternator.

 

[AWD-Tony]

I’m on my phone so I can’t see your log. Think you had about 5’ of timing towards the end of your pull. I’d get AFR dialed in and see from there considering everything else is dialed in.
