Hi guys,
Car: S3 after conversion to wideband
MAF: ori S3 BAM
VVT/SAI/O2/EGT = OFF
turbo: hybrid
SW: 8N0906018BH 0261207751 362999
KFDLULS/KFLDIMX/KFLDRXO/LDORXN/RLKRLDA/KFLDHBN - moded
KFNSWE/KFNWKHLLE/KFNWKHE/KFNWWLE - moded
I have problems with actual boost, which always drop down under specified on high rpm.
Looks like some intervention is adjusting PID control, n75 duty when we have underboost is not raising up, just stay on 75-80%.
When i loaded original BAM without any mods except (vvt+egt+o2), the same issue was visible (200mbar under specified boost).

Log I-part, modify IMX if necessary. Check KFLDRL too.

i raised for tests IMX up to 90-95% for specific boost, it doesn't help.
This issue occures also on ORI BAM software
On previous SW (narowband APY) the same HW configuration was working properly boost specified=boost actual.
Maybe something is wrong due to disabling VVT.

I limit, pre lin wgdc and p, i, and d.
Although I can guess your IMX is very wrong without it.

Nyet, please note that on ori software 18BH (with moded only krkte+CDNWS+ESKONF) i have similar issue, underboost 200milibar, and n75 duty cycle is not going up at all. log 115: http://vaglog.pl/log-002_115_033_L068a1.htmllog 118: http://vaglog.pl/log-003_118_020_2NS9L2.html.. i will check KFLDRL (but i think there was 95%) |

I still dont see any PID variables.
Anyway, possible mechanical issue. boost leak (bpv?), intake hose collapsing, or maybe just out of turbo if you can't find anything else wrong.
Also i don't see throttle plate angle.

Hi Guys,
I managed to collect some logs on new binary
This is time, actual boost almost meet desired.
Problem is just visible on high rpm above 6000rpm.
I left KFLDR in stock, KFLDIMX for high rpms adjusted to 93% (0.9bar) and 95% (1.05bar).
Please help with further investigation, I have still n75 duty cycle below 90% above 6000rpm
