1). Any boost, vac, or exhaust leaks?
No

2). Verified mechanical timing?
Yes

3). Verified base timing?
Yes

4). Ignition system
COP or Stock Coil: Stock
Wire brand and Age: Magnacore/2.5 years
Spark Plug brand, type and Gap: NGK-BPR7ES/.024

If you are having electrical issues, you should follow the troubleshooting method inside the FSM (that you can download off this sitehttp://www.dsmtuners.com/threads/download-the-1g-service-manuals.344490/http://www.dsmtuners.com/threads/download-a-2g-service-manual.324090/) and post the resistance reading.

5). Motor health (Compression Test)
Haven't done one recently but the last time I did do one was about 2 summers ago. Was 150-155 in all cylinders. I will do one as soon as the person who borrowed it confesses they lost it and gets me a new one or I get tired of waiting and get a replacement one.

6). Performed basic throttle body adjustments?
Idle Switch: Yes
Throttle Cable: Yes
TPS: Yes
BISS: Yes

7). Compression ratio
Ross 8.5:1

8). Any known bad sensors or brittle wiring?
No

9). Any DTC/CEL codes?
No

10). Electrical system
Car off (not running): 12.4 volts
Car running: 13.9 volts

11). Base fuel pressure and injector values
Base Fuel Pressure: 43.7
Injector Size (cc/min): PTE 880cc

12). Properly calibrated and configured wideband sensor
Sensor Brand: LC1
Calibration Date: Last week 4/3/2015

13). Type of fuel
Type: 93 Octane
Percent of Ethanol: 8%

14). Watched ECMlink how-to videos?
Yes


How does my idle log look before I start doing some cruise logs.

I finally sent my ECU in to ECMLINK to look over my ECU and upgrade from v2 to v3. I'm so dumb. I should've done this ages ago rather than buy stupid things for the car. Anyways. I got it back and installed my ECU to see how things run. It looks good. Fires right up. Did a some idle logging, etc. A few days later I swapped out my exhaust manifold gasket due to seeing bubbling coming from the manifold Got that done only to find out I had an exhaust leak between my o2 housing and DP. On top of that I somehow killed my o2 sensor. The o2 wouldn't cycle at idle which made my WB read rich.

So after fixing my exhaust leaks and swapping out for a new Denso o2 sensor this is my current log. I have done nothing yet other than adjust my dead time and BISS/idle to get my ICSpos as close as I can to 30. Anything I need to address?

Double check for boost leaks before making any of these changes.

TPS and TPS volts look good.

ISC never goes below 30. Its close but try to low it 2 more steps so that it floats between 28 and 32.

Your targeting 900rpm and the average is 856 for the 44 second log. Thats not to far off but it does seem a little “jumpy”.

Airflow per rev seems to be a little high. You need to adjust your MAFcomp to get your airflow per rev close to .25.

Combined fuel trims are always negative. When averaging a selection, they are about -3.0%. You need to adjust your deadtime to get combined fuel trims hovering around 0.

When you change your MAFcomp, it will change your combined fuel trims so keep an eye on Combined FT as you make airflow adjustments. Hopefully after fixing these, your idle will somewhat stabilize from where it is now.
 
Finally got a chance to trace down some boost leaks that I swear my brother and I never seen or heard before. I think my car is seriously messing with me. After they were all taken care of I found my compression tester and tested my car. 150 for all 4 cylinders. Also I swapped out to some new NGK BR7es. I also increased my deadtime from 330 to 345 to get it to where I am now. Did an almost 45 min cruise and ended it with 1 WOT pull. I'm running lean. Do I add adjust my fuel sliders at that given RPM range to lean it out? I need to turn down my boost to ~ 20-21 psi. Still on a stock 1g BOV and looking to help improve turbo spool. I'm not impressed with the turbonetics 50 I'm running. In car feel is not impressive at all. But what do I know.

Here's an idle log and WOT log from yesterday.

Thanks

You ISCposition is off by a few. Adjust your biss screw to get the ISC to hover around 30.

As for your WOT, you need to make these pulls in 3rd gear starting around 2500 RPM’s to redline.
 
From that short pull, it looks like things are lining up nicely. 9.5 is richer than I like to run so you can try leaning out the direct access tables to 10 or 10.5 and monitor knock.
