Since I've upgraded ecmlink from v2 to v3, I am not able to stop the knock.
Was running perfectly last summer at 20psi on 91 octane
This year, the car knocks at stock boost pressure
1). Any boost, vac, or exhaust leaks?
Boost leak tested 5psi above your max boost with no leaks?
No problem there
2). Verified mechanical timing?
Everything is aligned
3). Verified base timing?
5*BTDC
4). Ignition system
COP or Stock Coil: Stock
Wire brand and Age: ACCEL 8mm 150omhs/feet - 2013
Spark Plug brand, type and Gap: NGK BPR7ES 0.028
5). Motor health (Compression Test)
Cylinder 1:155
Cylinder 2:155
Cylinder 3:155
Cylinder 4:155
6). Performed basic throttle body adjustments?
Idle Switch: Adjusted
Throttle Cable: Like it should be
TPS: 0.63 volts closed
BISS: Around 30 at idle
7). Compression ratio
8.5:1
8). Any known bad sensors or brittle wiring?
Nothing that I know
9). Any DTC/CEL codes?
Nothing
10). Electrical system
Car off (not running): 12.2
Car running: 13.5-14
11). Base fuel pressure and injector values
Base Fuel Pressure: 44psi
Injector Size (cc/min):780cc
12). Properly calibrated and configured wideband sensor
Sensor Brand: Glowshift
Calibration Date: 217/06/03
13). Type of fuel
Type: 91 Shell V-Power Nitro+
Percent of Ethanol: 0%
14). Watched ECMlink how-to videos?
Yes
Also,
The knock sensor has been changed
The o2 sensor is new
Old fuel has been flushed
I've richen the air/fuel mixture from 11:1 to 10:1
I could not perfectionate the tune since the knock is stopping me
