Hi, this is my first time posting here as I just finally got my car together and first time with speed density. A little background: I started tuning with SAFC2 and buying EPROM chips from dsmchips back in the day. I got out of the dsm world for about 3 years and got back in after coming across a stock 97 GST for a great price. Mods are as follows:

3inch downpipe, megan catback
MHI s16g stock wastegate
rebuilt 7 bolt (stock)
injen CAI
ebay FMIC short route
ecmlink V3
LC2 WB simulating narrowband no gauge
850cc injectors
walbro190 w/ stock regulator
BSE kit installed
ngk bpres6 gapped .28
stock base fuel pressure
93 octane fuel

I followed the guide to get started. I adjusted the airflowperevsd to .25 +/- .1 by tracking corresponding cell in VE table. Adjusted combinedFT to within 0 +/- 3 and STFT hovering around +/- 4 from 0. from there I drove around for about 40 mins and logging data. I then copied the bold numbers to the ecu and saved. I've done a couple of 3rd gear pulls and it seems like it takes about 1000 rpms to switch over to open loop, but during the transition, boost is already around 6-7 psi, afr at around 13.x, some knock building and disappearing once it switches to open loop. during the transition, afr begins to settle around 12.4ish attributing this to the evo8 map iv'e downloaded as base from ecmlink. I am posting some logs to see what ya'll think, what am I missing, mistakes im doing, etc. I am a newbie at ecmlink and I am willing to learn, I just would like some guidance so I don't mess this newly rebuilt engine. I've been trying to add to the corresponding VE table to richen up the afr but no change. Im thinking i'm adjusting the wrong table. Appreciate the help.

first two pulls are 3rd gear pulls, map sensor indicating 21 psi boost. last log is a cruise log.

You keep saying your adjusting the VE table but I'm not seeing anywhere that your running speed density, as Dsmkauai suggested you want to adjust your fuel through the maxoct fuel table in the direct access section.

You have to add the displayed values.

Where's this info at?
1). Any boost, vac, or exhaust leaks?
Boost leak tested 5psi above your max boost with no leaks?

2). Verified mechanical timing?

3). Verified base timing?

4). Ignition system
COP or Stock Coil:
Wire brand and Age:
Spark Plug brand, type and Gap:

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

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

7). Compression ratio

8). Any known bad sensors or brittle wiring?

9). Any DTC/CEL codes?

10). Electrical system
Car off (not running):
Car running:

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

12). Properly calibrated and configured wideband sensor
Sensor Brand:
Calibration Date:

13). Type of fuel
Type:
Percent of Ethanol:

14). Watched ECMlink how-to videos?
 
1). Any boost, vac, or exhaust leaks? No, holds 23psi
Boost leak tested 5psi above your max boost with no leaks?

2). Verified mechanical timing? yes

3). Verified base timing? yes

4). Ignition system
COP or Stock Coil: stock
Wire brand and Age: ngk, 2 weeks
Spark Plug brand, type and Gap: ngk bpres6

5). Motor health (Compression Test)
Cylinder 1: 170
Cylinder 2: 175
Cylinder 3: 165
Cylinder 4: 170

6). Performed basic throttle body adjustments?
Idle Switch: n/a, 2g
Throttle Cable: stocks 2g
TPS: adjusted per ecmlink video
BISS: adjusted per ecmlink video

7). Compression ratio: stock 2g 2.0

8). Any known bad sensors or brittle wiring? no, cat o2 sensor disconnected

9). Any DTC/CEL codes? just the solenoids and evap as they were removed and disabled in ecmlink

10). Electrical system
Car off (not running): ?
Car running: ?

11). Base fuel pressure and injector values
Base Fuel Pressure: 43.5 stock 2g, stock FPR, Walbro 190
Injector Size (cc/min): 850cc FIC

12). Properly calibrated and configured wideband sensor
Sensor Brand: LC2
Calibration Date: 25 Apr 2016

13). Type of fuel
Type: 93 octane
Percent of Ethanol: 10% i think, whatever they have at the pump nowadays
