1). Any boost, vac, or exhaust leaks?
Boost leak tested 5psi above your max boost with no leaks? None
2). Verified mechanical timing?
yes
3). Verified base timing?
4). Ignition system
COP or Stock Coil: Stock
Wire brand and Age: NGK less than 6 months
Spark Plug brand, type and Gap: bpr7es gapped to .018
5). Motor health (Compression Test)
Cylinder 1: 170
Cylinder 2: 170
Cylinder 3: 170
Cylinder 4: 170
6). Performed basic throttle body adjustments?
Idle Switch: yes
Throttle Cable: yes
TPS: yes
BISS: yes
7). Compression ratio
9:1
8). Any known bad sensors or brittle wiring?
None
9). Any DTC/CEL codes?
None
10). Electrical system
Car off (not running):
Car running:
11). Base fuel pressure and injector values
Base Fuel Pressure: 47.0 (I know needs adjusted, just switched to a more accurate gauge)
Injector Size (cc/min): 1450cc
12). Properly calibrated and configured wideband sensor
Sensor Brand: AEM
Calibration Date: N/A
13). Type of fuel
Type: E85
Percent of Ethanol: Unkown
14). Watched ECMlink how-to videos?
Yes
Currently working with my tuner on an issue that was noticed after my switch to speed density. Did not get very far in the tune before he noticed it. The problem that he is having with my car is that the VE values are super high in boost, the car goes lean, and that is all with the injectors scaled down lower than they already should be even for E85.
What I have checked and know:
- Fuel pressure goes up 1:1 with boost so no pressure issue
- Injectors were cleaned of some E85 goo that they had one them and soaked in seafoam
- Fuel pump was checked for any leaks where it connects to the hanger.
This is what the VE table looks like:
This is what the important part of the log looks like (Log files are also uploaded to this post.)
I am sending out the injectors to FIC to have them flow tested and cleaned because to me and my tuner, that has to be the issue. But I was posting to here just to see if anyone else has an idea of what it could be that I could test in the meantime. Thanks.
