Icon1 Log Review - Troubleshooting CEL & Hesitation - 03-03-2022, 05:10 AM

Good Day

I have been experiencing a few issues with EWG N55. Issues listed:
- Hesitation in any gear and mode:ECO. Comfort, Sport
- Drivetrain malfunction: with the following errors:
+118001 Mixture ECU: mixture too lean
+120308 Boost Pressure Lower than expected
+108F01 Boost Pressure Lower than expected

The issue started about 200Km's after I used some octane additive (used multiple times prior).

Car currently has the following mods:
VRSF DP
Aluminium chargepipe
JB4 + running stage 5

I recently changed the spark plugs and ignition coils.

Please see review my log and advise me

1. What the potential issue may be
2. What are items for concern as shown by the log

Thanks

Sputtered and stalled? That's not going to be JB4 related, especially on map 0. I don't see anything in the log that would cause that since HPFP, trims, AFR's ect. look good.

However boost is below target, maybe a boost leak, or ???

I haven't checked for a boost leak.
Perhaps the better description I should have used is surged...similar to a misfire, but no codes indicating misfires.
Only codes are showing that I'm running lean.

Could my lpfp possibly be dying

Rail pressures looked fine so I don't suspect and LPFP issue. Sounds more like a boost leak.

I have uploaded a new log after addressing my boost leak.
Determined that the boost leak was coming from 2 places on the chargepipe
1. The rubber boot connecting the pieces together (had to replace)
2. Where the CP connects to the intercooler

Please check the attached logs and advise me if everything looks healthy.

You will need to run a full log per the necessary instructions before they can provide feedback.
