Mods are in profile.
So after my incident with the crank pully bolt coming out because I didn't loctite it, bent all valves, when installing the cams back into the head, I overlooked replacing the camshaft seals.
Eventually, it sprung an oil leak a few hundred miles later. Saturated the timing belt, and so I needed to replace it, even though it had less than 1,000 miles. Replaced that and replaced the cam seals and fixed the leaky mess.

After getting it back together and took it for a drive, went into the movie theater, watched the Fast and the Furious 4, came back out and did a small pull, and noticed knock was full on like crazy. SO now my car has a small amount of blue smoke coming out of the exhaust when revved a little at idle.

But now its just dog slow and knock is crazy high.
Logged it today to get this:

Anyone have any ideas?

 

[DSM_Zak]

Noone has any ideas?

I know for a fact the knock sensor has goo on the backside, and a new on is on the way, but I dont want to just throw parts at it blindly, maybe someone has had this same experience, and knows what it could possibly be.

Would a bad knock sensor cause this kind of detonation and timing pull?

....went into the movie theater, watched the Fast and the Furious 4, came back out and did a small pull....

Its this very same reason i was afraid of leaving the parking lot after watching that movie ..


Im trying to get an understanding on which one is your o2 sensor...

Not sure if its the FT02 or 02-F..
It says you have a 02-R which would be rear but 1g's dont have rear o2 sensors so that cant be it..

My guess is that its the FTO2 which isnt even read in volts..

Not toooo familiar with keydriver so some clarification would help

 

[snowborder714]

Please don't bump your thread.

Yes, having 43 counts of knock will cause the ECU to pull a lot of timing (if that's how the log is read - I've never seen something like that before).

 

[DSM_Zak]

I couldn't get it to sync for some reason, so that was all done in spreadsheet.

I was not bumping my own thread, furthermore. BTW if you realized, I was adding information, about my knock sensor so someone didn't post up about "check you knock sensor"
I don't see how thats a bump? Alright. Also, just bauce you have 3,000 post doesn't mean I'm an idiot or a newb, just means I don't sit on a website all day long. I have a job, and life.
I'm sorry but your USELESS post of information I ALREADY KNOW, bumped my thread. So please don't "bump" my thread with USELESS posts. Make more sense?

Just thought maybe noone has ever had these issues before (which I realize is not possible)

Keydiver: Evo Maf comp. 560cc comp. idle at 1K, knock sum gauge, what else do you need to know?

Once the knock sensor is installed this weekend, I'll see what happens.

*BUMP*

DSM PWR: I didn't know anything about it, but the "rear" was the only sensor giving me a change and seemed to be somewhat normal to a "front" voltage, as my car doesnt have a rear. So I assumed the "rear" one was the front. Thanks for have some sort of usefullness

 

[EagleTSIawd]

Looking at your log I see that your maf only reads up to 600hz, correct me if I am wrong but at full throttle and at that rpm shouldn't it be reading up in the thousands.

 

[myturbo]

how much boost are you running ?

im looking over these logs .there just kinda hard to read .im use to dsmlink

 

[DSM_Zak]

I don't know the answer to that one.
I do know its an un-hacked Evo MAF. Compensated with the chip, and plug and play harness from 1g-evo plug. So I know it's not the wiring.
I have no idea what Hz those run.

Sorry about the shitty, excelt picture post, I have no idea how to get it better or clearer, no matter what I did it came ou tlike that.

I'm running 20psi on the MHI E316g

EDIT: BTW the first log, the 02 was reading .33V not .88.

PIC HAS BEEN FIXED AND IS MUCH EASIER TO READ!

I just replaced my knock sensor for the exact same logs. Although mine in bone stock. Full 43 knock counts at WOT. The knock sensor oozed the black goo all down the back of the block, so I convinced myself there was nothing to insulate the 'sensor' parts inside, making it hyper sensitive. New sensor made zero change. I'm using MMCD and my log data looks just like yours.

 

[donniekak]

Sounds like you may have cracked one of your piston ring lands. The blue smoke is oil leaking past the rings into the combustion chamber. Do a compression test. At least pull the spark plugs and check for damage, or oil.

 

[DSM_Zak]

piston ring lands?
the motor was just built not even 10K ago.
How the hell do you do that?

would it do that with a bad knock sensor?
or atleast 43 counts of knock and timing being pulled?

I've heard of a bad 02 sensor doing this but I'm not 100% on that. How is your 02 sensor? Reguardless I need a new knock sensor, so, it only makes sense to try that anyways.

I did replce my 02 sensor, with a good extra one I had laying around. It APPEARED good atleast. If noone chimes in thats my next step.

I knew there was more of this randomness out there. Damn I swear to god my DSM gets every damn symptom of a DSM known AND unknown to man.

 

[SonySlave]

Well Zak it would be a lot easier if you could provide a couple different logs showing rpms from 2000-redline. That would help us read what's going on before and after the knock happens.

I'm telling you dude, you need to just pony up the money for DSMLink and be done with S-AFCs, chips, and palm pilot loggers. I'd help you out but you live a bit far still.

 

[DSM_Zak]

I know, link is on my list after cams and meth, SMIM, and this stupid problem is done.
For some reason my logger wont sync it.

it freezes everytime.

 

[rush2252]

Do some research I read for 5 hours last night literally on 1gs performing 43 counts of knock. Its a common issue with alot of people affected. The ECU pulls timing after 9 counts on the 1g so thats why your running like shit. From what Ive read after 4 hours nobody could give ONE simple explanation. Its referred to as "PK" or phantom knock


EDIT** I just found this by using ask.com and sorting through tons of articles. It appears the 1gs can pull timing upto 16degrees which is the max 43knocks. Here is the link my head hurts reading so much

I'm sorry Zak but you have your priorities WAY out of whack. DSMLink needs to come long before the cams, SMIM, or meth. You plan on tuning that meth with that ### S-AFC? Have fun with that.

You need to get your tuning situation fixed first before you continue adding more power. That E316G on pump gas w/ meth could make 400hp, but you aren't going to do it tuning the way you are. DSMLink was a godsend for me!

At least yours is pretty! My O2 is switching, so I'm wondering about Phantom Knock. I'm also curious if a boost leak would cause/cure this. The link rush2252 posted said "High timing + high airflow = knock". If the ECU is seeing a ton of air come in at WOT, then not all of it makes it into the cylinders, plus a loss of boost pressure. This stuff is still a little confusing to me. I miss my Holley!

The article also said the ECU disregards the O2 sensor at WOT

 

[DSM_Zak]

well the car is pretty sound and running right now (other than this randomness, its def, not phantom knock, my motor sounds very quiet and clean and idles pretty good, replacing the ISC next week.), I just havn't researched link enough to know the differences.

Maybe you're right, Mike, I just know the more power adders I'd like to have, Link is def. on my list, but before I even buy ANYMORE power adders, I will def. be researching, and let alone getting these little bugs worked out.

 

[MY1GDSM]

I would'nt be out doing pulls to redline when getting 43+ counts of knock ...
I would be still looking at the logs... but if you do I would log alot less then all that at that rate you won't have that much usefull info . When are you first starting to see knock?
Figure out your issue sync'in and get a real log up...

 

[MY1GDSM]

Sounds like it to me also...That is If it is smoking real bad...
I would do a leak-down test as well it may tell you alittle more just to be on the safe side, I cracked a ring land once and it took quite a while before I Really started losing compression I did'nt even know I did till I did a leakdown on it..

 

[DSM_Zak]

not smoking real bad at all, just when revved a little and going back down to idle, a little blue comes out. thenw hen driving a little, not massive like a blown turbo.

43 counts is the maximum counts the 1g ECU will read.

At least read the link. I spent the time to post it up. PK phantom knock meaning that there is technically no knock its the knock sensor picking up vibrations of some sort. Some people experienced this when running rich or the Intake temps reached unusual highs.
Read the link in post (#15) itll help

-Kolby

EDIT** not sure im reading this right but @6000rpm your injector duty was only 66%? If thats the case your running uber lean and this could be your knock

unless he is running big injectors ???


have you checked all the timming ? it could be it but i dont know because this is very confusing

 

[rush2252]

Read that link!! wow.. it explains ALOT of useful good info. Im glad I dont have a 1g because it seems like the 43 counts of knock is a common common issue.

-Kolby

 

[rush2252]

Theres another post in the problem diagnosis. The guy with same problem very similar logs double checked timing he said his belt was like one tooth off. He set it back and said it solved the 43 counts. He come to this conclusion by advancing his timing to 10-12BTDC

Just a suggestion but +1 on checking your timing
