NOTE: Do NOT activate the MaxxECU Default V1.3 CAN output on the same bus as the DSG, cause it will interfere with the control operation and cause trans going to neutral and random strange issues.

NOTE: PDM20 uses the 0x50 CAN message ID for communication, which might be available on some Audi (equipped with airbag modules), do NOT use on the same bus!

 

 

 

How to get your VAG DSG DQ250/DQ500 gearbox up and running with MaxxECU

 

1. Hardware requirement and wiring

Make sure your DSG TCU is supported.

 

Currenty we only support the VAG DSG DQ250/DQ500 gearbox found on VAG MED 9.1 ECM vehicles.

Note: We do NOT support the DSG gearboxes found on vehicles using the SIMOS ECM.

* It seems that some DQ200 have the same hardware number but we never tested them, please be careful as we cannot assure you that the DQ200 will work with our VAG DSG CAN protocol.

Note: It might work with other TCU numbers also, if you are having problems with a specific number, or want to report a successful DSG control, please contact us.

 

Read the VAG DSG (DQ250) wiring or VAG DSG (DQ500) wiring and install the OE VAG shifter found together with your gearbox, unless you intend to use the DSG Shifter emulation.

Note: Stock gearbox will handle: DQ250 400-450Nm, DQ500 800-850Nm before slipping, you need to update your DSG TCU with a improved firmware to handle more torque + new clutch package to withstand more torque.

 

 

2. The DSG CAN protocol.

It is wise to read how and understand how the VAG DSG CAN Protocol works, what is needed and make sure there is no CAN collisions on the selected bus.

 

 

3. Configure needed inputs.

Since you have read the VAG DSG (DQ250) wiring / VAG DSG (DQ500) wiring pages, you fully understand what is needed to make this protocol works and all proper wiring has been made.

 

clip1119

3.1. Activate the digital input brake pedal/stop light active. Inputs --> Digital inputs and make sure the active level from 0 to 1 when you press the brake pedal in the RealTime Data view.

Note: The brake switch is NEEDED for the DSG gearbox to work, you cant engage any gears without it.

 

clip1120

3.2. Mount at least ONE wheel speed sensor, and enable it. Make sure it is configured and properly adjusted. It is extremely important that the wheel speed is 100% accurate! <-- VERIFY with GPS.

4. Activate the CAN protocol.

Now it is time to actually make MaxxECU transmit the CAN protocol to the wired DCT TCU.

 

clip1493

4.1. Activate the Powertrain control in CAN Bus --> CAN settings.

 

clip1348

4.2. Verify that the CANbus load increased with ~25% when the protocol is activated.

Note: if the CANbus load does not increase during the activation, it means you have wired it wrongly or the TCU is not responding.

 

clip1349

4.3. Make sure the Gear calculation is from CAN protocol (OEM) setting, found in Speed/Gear --> Speed/Gear, gear calculation.

 

clip1714

4.4. Select the gearbox type (DQ250 or DQ500), shifter and paddles to be used.

Note: the CAN emulation option should only be enabled if the no Vehicle CAN is presented, you most likely want that option, unless you are in a MED 9.1 vehicle.

 

 

5. Make sure there is no TCU error codes.

Using any ODBII scanner or preferable VAGCOM (VCDS) diagnostic interface, make sure there is not stored error codes, if so, please erase and restart the TCU.

Note: If everything is correct, there will be NO error codes in the TCU with MaxxECU CAN protocol activated.

Note: During a MaxxECU firmware update, please disconnect DCT TCU power, since it will otherwise give you very weird error codes, OR always make sure to erase and restart TCU after a MaxxECU firmware update.

 

 

6. Get to know available RealTime Data values.

 

 

7. MTune DSG Settings.

Now, you are starting to understand the DSG control and it is time to start playing with the MTune configuration DSG settings.

We now just expects you to head over to DSG settings to read, and fully understand.

 

 

8. MTune DSG Control.

This is the fun part, where you will try to put in a gear and give it a little bit of throttle to scream of happiness that the vehicle actually moved (hopefully).

Head over to the DSG Control setting page, read information, understand an start to adjust.

 

 

Note: Shiftcut event is automatically triggered from the DSG TCU before an up shift, and a Throttle blip command is sent during a down shift.
