Need info on what tune/dsmlink

[Brandon2gsx]

Hey guys. My names Brandon, I do a lot of research on here but not a lot of posting. I purchased a 95 gsx in March and in trying to get it up to par. The following mods are:
td05 18g, fic 650 injectors, aem fuel rail, vrsf fmic, black works radiator, ported exhaust manifold, srs 3" catback, dsmlink v3, Eprom ecu, autometer phantom boost gauge, Hallman boost controller, greddy turbo timer.

I just figured out how to run the dsmlink on my Mac computer and I've been messing around with logs. Now, I'm some what familiar with it but not too much. I did a 3rd gear pull and heres what I got. Need some opinions..
Rpm: 6684
Airflow: 249.0
Front o2: 0.98
Timing: 6.8
KnockRet: 8.4
ThrotPos: 73%
Didn't catch the afrs but normally I run around 10:5-11:0 at 16lbs of boost. The knock is what I'm worried about

That's a ton of knock stop before you blow her up!!!

 

[Brandon2gsx]

That's what I was thinking. How do I go about fixing it. A buddy of mine said to pull timing .5 at a time until it drops

Up until 4K rpms there's 0 knock. After that it increases.
4150-5200rpm: 1.2-2.1 deg
5300-5800rpm: 3.5 deg
5800-6250rpm: 4.2 deg
6300-6600rpm: 7.0 deg
6700rpm: 8.4 deg

Dude, this isn't 2003. Post an actual log if you want help.

 

[Brandon2gsx]

I wouldn't waste time writing it if I knew how. Sorry though, let me see if I can.

That better?

 

[GST with PSI]

No, not better.

1) Go create a DSM profile: http://www.dsmtuners.com/threads/we...o-create-a-dsm-profile.499707/#post-153564173

2) Go square your car away and capture a log after it's mechanically sound:

Here's the format ---> http://www.dsmtuners.com/threads/wa...r-receive-no-replies-from-the-wisemen.443297/

Here's an example of how to fill it out ---> http://www.dsmtuners.com/threads/first-time-log-wisemen-just-look-away.495794/#post-153536533

Next, make sure you're capturing the correct values for the type of feedback you are seeking. See here for what values to capture ---> http://www.dsmtuners.com/threads/list-of-values-to-log.444831/

3) Upload your log: Click upload file (next to orange "post reply" button below) --> navigate to log --> click "open"

See you in two weeks.

Driving with knock that much glad you sorting it should run a lot better after you reduce it. The boost gauge is so nice to see when you have knock

 

[ceedawg]

Up until 4K rpms there's 0 knock. After that it increases.
4150-5200rpm: 1.2-2.1 deg
5300-5800rpm: 3.5 deg
5800-6250rpm: 4.2 deg
6300-6600rpm: 7.0 deg
6700rpm: 8.4 deg

You will be sending this engine to motor heaven before you know it. You should have stopped when she hit 2.0 degrees or even a little less!!!!! But 8!!!!!!!!!!! Im surprised the motors still sound. Do what GST is telling you and don't/stop pushing the car like a madman before you get it properly tuned we want to see you happy and have her running right.

You need to turn the boost as low as it will go and start from there. I also suggest that you get on ecmlink forums and learn more about how to set up the base parameters and get familiar with the software before doing any more wot pulls. You are definitely, if you haven't already going to do damage to the headgasket or piston ringland.

Thanks guys! I appreciate the help. The car is down and will not be driven till its figured out.

Thanks guys! I appreciate the help. The car is down and will not be driven till its figured out.

Best thing to do is have a wideband hooked up to yr ecu so u can log afr on log with out that no one will ever be able to tune yr car that is the very first step nothing else

 

[Brandon2gsx]

I'm not too sure if this has to do with the knock but my idle was surging also. On startup it's fine, but after driving around a little and depress the clutch, the rpms drop to about 500-700 and the car just about dies on me. Battery is a week old, alternator tested fine, ISC tested fine and motor is good on it.

 

[enriquez2000]

Follow what GST said or no one can attempt to help you with any part of this!!

 

[Brandon2gsx]

Update on the car: ended up getting everything sorted out. Had a variety of wiring that was replaced, sensors, gaskets, leaks, etc. Checked everything to be prepared for tuning and it was good to go. Long story short, my tuner was able to get my car running beautifully at just 17psi, until after one pull the car randomly died. Started it back up and what do you know, she has a knock has nothing to do with my tuner... Think it was just time for the motor to go. Unknown mileage from when I bought it, just wanted to get a good tune because the PO never did a thing to it after his mods. So the car was like absolute crap. So, now the 6 bolt comes sooner than planned thank you guys for your help also!

 

[1990TSIAWDTALON]

How did the tuner get rid of your knock before she went south? Just wondering if you knew?

 

[Brandon2gsx]

Added fuel and adjusted timing I believe

 

[1990TSIAWDTALON]

Yep it bet it perked right up....and then..... sorry man. It can be fixed.

 

[Brandon2gsx]

It what? And yeah, but I'm just using this as an excuse to swap in a 6 bolt haha

 

[1990TSIAWDTALON]

They're both good engines. I am glad that I got to start with a 6 bolt.

 

[8716valver]

6 bolt has my vote
