Quite simple, it started out as an Emergency Diagnostic tool for the GS-range of motorcycles. Now we cover almost all of the models that are equipped with Electronic Fuel Injection (EFI).

What is it?
GS-911 is a unique software and hardware combination that allows the BMW enthusiast the ability to communicate with the control modules in a safe and controlled manner. In the true spirit of adventure associated with these motorcycles, the tool is available with both WiFi and USB interfaces, allowing you to use it wherever adventure may take you.

It has all the advanced features to do most of your maintenance, from advanced Service functions on the Engine controllers, bleeding of the ABS units, to resetting Service Reminders.

What is it not?
It is not a mechanic. It does not automatically fix the problem – it still requires human intervention. Please don’t expect the device to teach you to become a master technician.

The GS-911 is a tool, not an online service manual. We can not possibly document every function and procedure you can do with it for every year and model of BMW motorcycle that GS-911 can be used with.

What else do I need?
A good repair manual. There are good 3rd party manuals with good literature on the BMW bike models and most dealerships sell model specific Technical Repair DVDs. In addition, there are great technical DVDs by Jim von Baden that are available through our online store, directly from Jim and through most of our distributors.

• Read Diagnostic Fault Codes
  • This shows the Fault codes and text descriptions of the faults stored on the Electronic Control Unit.
• Shows ECU information
  • See hardware and software versions, manufacturing dates, and other manufacturer related data.
• Clear Diagnostic Fault Codes
  • Enables you to erase fault codes once the problem has been fixed.
• Show Real-time data (Live data)
  • This is available on all Engine ECU’s and many other ones, and shows the input, output and sensor data to the specific ECU.
• Service & Maintenance functionality
  • We are increasing the coverage of this functionality as we go along… This includes resetting of Service Reminders, Idle Actuator Calibrations, Locking of Idle Actuators for Throttle Body Synchronization, Adaptation Resets etc.

Chipped bikes are always difficult to predict.. however, if it is a quality chip, then all should work well..
I have the BB Power chip in my 1150GS… and the GS-911 works great.. completely like it should !

Piggy-back devices, such as Techlusion or PowerCommander however, change the Injection (and/or timing) signal after the ECU, i.e. without the ECU knowing about it… thus, if you have a real-time value reading of Injection time of 2.50ms, but you are running a PowerCommander that adds nother 10% at that rpm/TPS operating point, then your real-time value that you will read from the ECU will still show 2.50ms, while the actual injection pulse will be 2.75ms (because of the addition of the 10% (0.25ms) of the PowerCommander).

The LED is a status indicator – there to help you… This is a very helpful little function, because you could be battling for hours trying to figure out why you can’t get any communication with a controller on the bike, and in the meantime your comms line is shorted thus preventing any comms…

• Green: your GS-911 interface is powered up and all is good
• Blue: Bluetooth of course – the LED will be blue when it is communicating over Bluetooth
• Orange/Yellow: if you’re getting this while the Firmware is updating – don’t worry… that’s what its supposed to do! Any other time :- hit the [Test interface] button, as your interface requires a Firmware update.
• Flashing Red: once you plug the device into the diagnostic plug on your motorcycle, and it flashes red, switch the ignition ON and see whether it turns green – some controllers seem to take the K-line (comms line) low, when the ignition is OFF – if it turns green when you switch ignition ON, don’t fuss… If it still flashed red with ignition ON, you have a shorted K-line… typically a wiring problem, but could also be a controller problem. Now go to the Setup window and press [Test Interface] this will tell you which K-line and whether it’s shorted to Battery Positive or Ground.
• Permanent Red: A Fatal Hardware malfunction occurred, please contact the HelpDesk.
• Alternating Red/Green flashing: This flashes when there is communication between the GS-911 interface and the motorcycle, and you are connected using the USB port.
• Alternating Red/Blue flashing: This flashes when there is communication between the GS-911 interface and the motorcycle, and you are connected using Bluetooth communication.

The GS-911 is not getting any response from the ECU(s). This could be because of several reasons.

1. that you are NOT choosing the right model.
2. if you have chosen the correct model and you still don’t get a response, then there are one of two problems…

• the diagnostic connection between the connector and the engine controller is severed (highly unlikely, but possible), or
• the ECU is not powered or not in a condition able to reply (more likely)

Reasons for the latter could be:

• Immoilizer/Alarm still engaged,
• kill switch NOT in the RUN position,
• Ignition NOT ON
• Neutral NOT selected.

The best way to check this would be to have the bike in Neutral, and start it… while it’s idling connect GS-911 and connect to the Engine controller – If you can connect, then you’ve had one of the issues in (2) above… if you can’t then you have a wiring problem.

Functionality is upgraded by downloading and installing the latest client software. If a firmware update on the GS-911 device is required, this will be done automatically once you have the GS-911 device plugged in and run the updated GS-911 Windows software. Thus it is completely field updateable and does NOT have to be returned to us (or our resellers) for firmware updates etc.

Our release cycle works as follows:

The GS-911 PC English version is the main version and we aim to update it every 2 months. Once the English version is updated, the translations of the PC version are initiated – thus translated versions may be behind in the functionality of the English version.

The Mobile software will be updated as needed and where possible – but in general the update cycle is slower.

Yes it can! – as of the 904 release version (that means April 2009)! This is available on ALL models that support Service Reminders (as of factory build September 2007).

To view and reset Service Reminders:

• Select your model Series (e.g. F-Series)
• select your model (e.g. F800GS)
• select “Special Functions” (on the same panel where all Control Modules are listed)
• select “Service reminder”

…the rest is pretty easy… child’s play! 😉

Here you see the Service Reminder screen… it shows current detail, such as Odometer reading, Motorcycle date, and Service Due date & mileage.

2 Buttons…

• one that resets the Service Reminder with default values (one year from today AND 10,000km/6,000mi from current Odometer reading.
• another that allows you to choose your own custom date as well as custom mileage (for advanced users 😉 )
