Im trying to get some knowledge about DSG DQ250.

I have some parameters that can be of interest.. I´ll post them here and maybe people can discuss further. Ill post my progress and testing here aswell later..



2F56 Max Momentenanstieg Anf. bei aktiver Launch Control
(Maximum Torque at launch?)

442 Diagnose: Maximale Ausgangsspannung am Drucksensor

521 max. Zeitdauer für die Freigabe des Abbaues durch die Zusatzparabel

89A maximale Abtriebsdrehzahl Launch Controll

89C minimale Temperatur Launch Controll

8A8 Schwelle Bremsdruck für Aktivieren LaunchControl
(Minimal Brake pressure to aktivate launch)

8AA Schwelle Bremsdruck Bremse lösen in Launchanfahrt
(Brakepressure minimum for launch)


130C Begrenzung Momentenvorsteuerung

134C max Drehzahl für Gang (?)

1744 max. Motormoment Getriebeschutz

174A Freigabe Motoreingriff LaunchControl über Fahrgeschwindigkeit

1774 Sollstrom fuer Hauptdruckventil

17B0  Daten Moment zu Hauptdruck KL

17D0 Maximaler Hauptdruck

25FE maximale Motordrehzahl

2684 Max-Drehzahl fuer naechsten Gang nach RS bzw. HS-Schwelle bei BergabStrategie in D



These are interesting!!

959 Filterzeit Bremse erkannt für Einstieg LaunchControl
(Time before launch?) (800ms)

95A Filterzeit Bremsdruck Bremse lösen in Launchanfahrt
(??)


I anyone have dokumentation post it Smiley

What I have found out is, that clutch pressures can alter a little from the ECU side by minimize the dsg seen torque when driving at light throttle and show 500Nm when flooring. I think that it's the microslip adaptation which can be altered like that. Other thing I found regarding the launch and accelerating from standstill is rlsol filter, at least with small turbo it makes difference to shorten the filter. Wise please correct.

I have tunes some dq250 tcu's and i have a way faster launch delay by seting  " Filterzeit Bremsdruck Bremse lφsen in Launchanfahrt " from 40 ms to 10ms

I have the later DQ250 im reading via KESS tool it worked without any problems. But some need

These are intressting i could try to adjust these parameters and se if launch activates quicker.

Adress from TEMIC Ols above.

959: Filterzeit Bremse erkannt für Einstieg LaunchControl
(Time before launch?) (800ms)

95A: Filterzeit Bremsdruck Bremse lösen in Launchanfahrt

If you use TEMIC ols and you have newer DSG try to compare maps in WinOLS with HiLo and LoHI then its much easier to compare and find maps..

In order to disable kick down i lower the downshift tables for " S " & " D " .i make them their upper rpm values near to 3000rpm and then there is no kick down.



I use kess V2 for read/write the dq250 tcu's i normally read them directly from the tcu conector and i write them via cars obd .
