Title: [ME7.1] looking for solution for raising starting throttle opening Post by: Rocky on January 02, 2018, 05:13:08 AM Hi friends
ME7.1 2.8 VR6 injectors bosch 630ccm i'm looking for solution for raising starting throttle opening. Starting rpms are very poor, even my target idle rpms are set on 1000. Without touching Acc pedal there is no chance for start. in me7.1.1 r32 damos there is module WDKSOM: "2.40 Berechnung Drosselklappensollwinkel ohne Momentenstruktur" KFWDKSST Sollwert Drosselklappenwinkel im Start - there is start throttle angle. i have tried: BBKHZ: "18.280 Betriebsbereich motorisches Katheizen" KFNLLKHM KFNFSKHM LLRNS: "541.220 Leerlaufregelung-Solldrehzahl" FNSSTM FNSSTKM STADAP: "6.80 Startmengen-Adaption" NSTAK DNBURN0 DNBURN1 DNBURN2 KLDNFHO with no effect. Have some idea how to increase starting rpms to 1200 than falling to normal idle?

U mean this module?: LLRRM: 6.60 Leerlaufregelung Reglereingriff Drehmoment IVDN - LLR: I-Verstärkung bei stehendem Fahrzeug IVDNV - LLR: I-Verstärkung bei rollendem Fahrzeug PVDN - LLR: P-Verstärkung bei stehendem Fahrzeug PVDNV - LLR: P-Verstärkung bei rollendem Fahrzeug PVLDN - LLR: P-Verstärkung bei stehendem Fahrzeug (Luftanteil) PVLDNV - LLR: P-Verstärkung bei stehendem Fahrzeug (Luftanteil) Is this have influence on starting, cranking?

PVDNHOM PVLDNEZ IVDNDTEH IVDNHOM IVDNHOMV My broplem was weak idle and got it sorted. I'm pretty sure that the starting got better too. Try P things first. |
