How to Read and Write DQ250 MQB with Kess V2

Confirmed! Genuine KESS V2 is able to read and write the Control Unit of VAG DSG DQ250 and DSG DQ250 MQB transmissions. but a new 144300K267 dsg cable and the genuine programmer are required!

new 144300K267 dsg cable to flash mqb dsg:

uses the same cable as the old DSG DQ250

Difference between old and new dq250 is that you add a 12v 5 amp switch to the positive main power cable, when it prompts you to cycle ignition, leave the main DSG switch on, and cycle the switch that you just installed when prompted.

Schematic of the cable I have used for DQ250.

Also a photo of the cable set I have made with changeable adapters for DQ200, 250 and 500. The clips for battery connection, box with ignition switch and the connector to KESS box is re used for all adapters.

With the drivers included in ECM Titanium, you’ll be able to modify the operating parameters of the gearbox Temic DSG MQB in order to increase performances.

FEATURES AVAILABLE WITH ECM TITANIUM FOR DQ250 MQB:

*   Upshifting maps: they manage the shift to the upper gear in all the driving modes available on the vehicle (ECO, Normal, Sport, Winter). They indicate in RPM when the gear shift occurs.
*   Downshifting maps: they manage the shift to the lower gear in all the driving modes available on the vehicle (ECO, Normal, Sport, Winter). They indicate in RPM when the gear shift occurs.
*   Launch control:the launch control is an electronical system to avoid the slipping of the drive wheels when accelerating rapidly from a standing start. Thanks to the maps of launch control it’s possible to increase the RPM maximum limiter.
*   Maximum torque limiters:in addition to the limiters of the ECU, it’s possible to modify the transmission torque limiters to increase the performance of the vehicle.
*   RPM limiters:you’ll be able to modify the RPM limiters of the transmission too, to achieve better performance.
*   Timing maps:they’re expressed in ms (milliseconds) and enable the shifting timing modification.
*   Maximum oil pressure:it’s possible to increase the shifting speed, by increasing the oil pressure of the transmission.

It’s VERY VERY VERY IMPORTANT: you should have the Auto ECU Programmer Kess V2, not china or eu clone. with the clone you have no luck with VAG DSG DQ250 and DSG DQ250 MQB.

Also, KTMflash is a good investment for DQ250 MQB

Cheap China clone KTMfash also works good for DQ250 MQB!
