Title: ME7.5 actual load at part throttle higher then requested = P1335 Post by: curamrdan on March 16, 2022, 02:55:41 PM Hello, enclosing example, car is 1.8T with 512kb ecu. Its 180hp version, with setup from 225 (turbo,injectors,maf). Every time at 2000rpm actual load become higher then requested, also airflow at throttle body become lower than actual, fueling become rich.
At that log, thows also P1335 tq monitor level 2 error (no matter when i try to overcome it by FF kfmiz... maps ect). Copied ILR/IOP maps form 225, but still the same situation, since 2000 exactly. I know that turbo has tightened actuator, so reaching 0.5bar, so i little upped KFVPD... axis, but this is happening say 0.2bar... My next attemp will be readjust throttle maps by real values from maf, as its only i see wrong. At wot if follows correctly. What im missing?

Sent from my Redmi Note 9S using Tapatalk do you need anything more then i enclosed? I see it happends when requested boost is zero, but actual is becoming positive and when reach cca 50kpa difference , problem begins. So i must modify ILR/IOP to request boost at low mifa or adjust throttle maps to suit more flow which maf reading(no matter what is more accurate, it may be closer to each other?).

Title: Re: ME7.5 actual load at part throttle higher then requested = P1335 Post by: aef on March 17, 2022, 12:44:43 AM log was performed with unplugged n75 or why is wgdc 0?
log pedal position Title: Re: ME7.5 actual load at part throttle higher then requested = P1335 Post by: curamrdan on March 17, 2022, 03:16:03 AM Log was with N75 connected, but there is not request boost, co no wgdc needed. Its partial throttle (mifa request 20-30%).
Car has aftermarket blow off valve, twin piston type, so i will try to remove it. But when there will be leak, there also will be no boost or atleast will not spool too much.

Title: Re: ME7.5 actual load at part throttle higher then requested = P1335 Post by: curamrdan on March 17, 2022, 12:35:55 PM Done. It was done by bov, stock one solved the issue :)
