ECMlink Can't get rid of knock....

[GST with PSI]

First, dumping E85, race fuel, or whatever else you can conjure up is not a solution to this problem.

Second, if you want good tuning advice, you'll need to fill out the template. You saying it's all good is worthless to anyone really trying to help you. We use the information in the template to help evaluate your tune. Without the information, you won't get any feedback. This format allows those willing to help you to easily verify your car is in good working order before time and effort is invested assisting you with tuning advice. You can't tune a car that's not 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/

Next, go create a DSM profile and compile a complete mod list for you car. The more details you provide, the more it helps others help you without having to ask a bunch of redundant questions about what's done to your car. You can view my profile for an example of a comprehensive mod list.


Your log:

At a glance, your timing is probably part of your problem. It's typically sitting at 20+ degrees as you start to roll onto the throttle, then drops way down as throttle input increases and the car transitions into open loop (as it should). In your case, the timing is then being further retarded when the car starts to knock. In the lower RPMs, load is high, and your timing is also high (advanced) while in closed loop. I believe this is translating into knock as you roll onto the throttle, transition into open loop, and further increase the load on the engine at low RPM. Sadly, I think it will be difficult correct an issue like this with DSMlink 2.5, as you don't have the direct access feature that would allow you to access the open loop fuel and timing tables. With direct access, it may be possible to use your log to identify what cells are being highlighted when the car transitions from closed to open loop, and pull some timing in the affected areas. To get the DA feature, you'd need to upgrade your 2.5 to V3 http://www.ecmtuning.com/product_info.php?cPath=25&products_id=37

Does the car knock at WOT? Can you post a log of a 3rd gear pull?

Complete the steps above, and you'll get the help you need. If you don't, you'll probably be stuck with the vague info you've been getting.

 

[Lolmooses]

1). Any boost, vac, or exhaust leaks?
Boost leak tested 5psi above your max boost with no leaks?

Tested system last Saturday at turbo and throttle body using soapy water, could not find a leak.
2). Verified mechanical timing?

Timing is spot on.

3). Verified base timing?

5* BTDC is where it's set at

4). Ignition system
COP or Stock Coil: stock
Wire brand and Age: NGK, less than a year old
Spark Plug brand, type and Gap: NGK BPR6ES gapped at 0.28

5). Motor health (Compression Test)
Cylinder 1:140
Cylinder 2:145
Cylinder 3:150
Cylinder 4:145

6). Performed basic throttle body adjustments?
Idle Switch: simulated through link
Throttle Cable: yes
TPS: used links TPS adjustment tool and adjusted it for 0.63v at 0% throttle position
BISS: ISC Wont go above 19-22 with the BISS screwed all the way in.

7). Compression ratio

Stock 1g pistons 7.8:1 I believe

8). Any known bad sensors or brittle wiring?

Replaced every sensor in the car except for the coolant sensors which were still ok.

9). Any DTC/CEL codes?
no

10). Electrical system
Car off (not running):12.6v
Car running:13.5

11). Base fuel pressure and injector values
Base Fuel Pressure:37 PSI stock regulator
Injector Size (cc/min):450cc stock injectors

12). Properly calibrated and configured wideband sensor
Sensor Brand:AEM UEGO
Calibration Date: Calibrated through linearWB yesterday. It's as close as I can get it.

13). Type of fuel
Type: pump gas 91 octane
Percent of Ethanol: 10%

14). Watched ECMlink how-to videos?

Many times

I made a profile for my 1g like you suggested. All values except for ClutchSw are being logged. Unfortunately I didn't see this thread before I made my most recent log earlier today. In my most recent log I reverted the knock sensor to reading all the time and I noticed it actually starts to knock at 2200-2500 rpm when I'm still in vacuum and continues to climb until I let off the throttle. Before I had it set to stop detecting knock below 3500 rpm and 50% throttle so it made it SEEM like I was knocking right when I started building boost.

Im not doing WOT pulls because it spikes up to 10+ degress of retard very quick, but I do have an older log with several WOT pulls. I've attached my most recent log where I reverted the knock sensor monitoring back to stock.
