put the logger on, knocking!

[ITSME4G63]

Hey guys, ever since I got my car back together (this past Sunday the 7th), when driving it, I noticed a hesitation from time to time. It would just come out of nowhere, one minute id slam the gas and the car moves out!!! Then other I slam the gas and it falls on its face, still boosting the same psi as it was when it moved out. I also noticed this hesitation, when the car moved out and I approached 5k rpms. So I finally slapped the logger on, on the way to work this morning I was looking whats going on, low and behold, its knocking like a woodpecker when I reach that 5k rpm range! 43 counts of knock and I know that means that the knock sensor is being maxed out. I checked the o2 trims, and they are dead on at .83-.85v, the timing at this same rpm is around 21°. What is going on?!!! The hesitiation that comes out of nowhere didn't occur this morning for some reason but when it does Ill be checking the logger as well. The motor has 150 miles on it and so does everything else in it, the knock sensor has like 650 miles on it, there is a minor exhaust leak between the exhaust manifold and the turbo (which I should fix this weekend or next via replacing a good surfaced manifold). Could this be a case of an over-tightened knock sensor? I will check the sensor itself for goo, which I doubt will be present. Another thing, Im not sure if its my alternator whining or the cams, but would this contribute in a way? The knock is at 0 count until that 5 k rpm range! Help!

the car is running a 2g maf with a zero'd out afc1 if that helps. and 550 cc injectors & a 16g, walboro 255 rewired and afpr set at 43psi

Add fuel immediately, the 2G MAS reads a lower frequency for any given RPM compared to the 1G MAS. Add about 10% across the board and re-set the ECU, for I'm sure all your fuel trims are maxed out.

fuel trims are something like this

117%
100%
100%


Oh and I added the car has 550cc injectors.

Oh and If someone could tell me how to extrude logs from a pal m100 Id appreciate it.

 

[KeltonDSMer]

The 550's add about the same amount of fuel that the 2G MAS takes away from reading a lower frequency. The corrections on the AFC will not be very drastic.

I would make sure the knock sensor is in tight, a loose sensor will read knock all day.

Also, check for post MAS pre turbo leaks, for unmetered air will enter under boost.

I set 10%+ across the board, the car never felt better! Looks like I wasnt getting enough gas! Didnt reset the ecu though.

 

[ITSME4G63]

too soon to be true, the car felt better but still doesnt drive right, at 5k rpm I get massive backfrie at wot! and sometimes get a hesitation out of nowhere when pulling from a stop, the hesitation is knock for sure, i see it on th elogger.

Please, just post RPM, Knock, Timing, and maybew O2. That is too hard to read.

[Dream On]

Fix all your boost leaks and pre turbo exhaust leaks, then do another log.

 

[TimG]

Are you even at WOT for those logs? You are basically hovering around 2500-3500rpm and logging a bunch of worthless data.

If you are knocking under a mild cruise, it's phantom knock (aka - lifter tick, exhaust leak)

 

[ITSME4G63]

I think all of these are ful throttle, there are no boost leaks. I will do another wot test today, but that crazy knock happens randomlly.

ok did a log

from previous logs I did notice it was runnign super rich when it started to hesistate around 5k rpms, So I pulled 10-15% fuel away from then and on and voila, the car just like woke up!

What do you all think'?

I think all of these are ful throttle, there are no boost leaks. I will do another wot test today, but that crazy knock happens randomlly.

If the above logs are actually full throttle, then you have a major issue with your TPS. In the first logs you posted, the TPS value never exceeded about 85%. You need to fix you TPS and then make a 3rd gear pull from 2.5k to REDLINE. Log timing, airflow, rpm and knock.

Yeah in those last two logs, your timing numbers are really weird...
