Anyone try their GS-911 yet?

I have the Bluetooth model. Spent 10 minutes trying to initialize with the notebook with Bluetooth. No go. It showed the correct port number, and the notebook saw the GS-911, just never opened the rest of the program and only got about 1 green bar on the Initializing screen. The green LED on the GS-911 changed to Blue like it was going to start, but never did. So much for Bluetooth.

Shut program down and used a USB cable. Restarted program and it launched. Guess the Bluetooth is a bit fickle.

Here's the odd stuff I found:

It says there are 8 Fuel Injectors (??) and a TEST button for each of the eight. The notes say "You will hear a clicking noise when the injector gets the test signal." After pushing the TEST button for injectors 1 through 4, I heard nothing at all. Injectors 5 through 8 clicked as it said. Dunno what that's all about as the MAX BMW sheet says it has 4 Injectors and not 8.

Then, the Tank Valve Vent Test is much the same as above. "You will hear... on U.S. model bikes only." Nope. I didn't hear anything. Odd.

Other tests seemed to work. I didn't perform the exhaust or flapper valve test or do any correction which they say is used "To correct for stretch in the Bowden cable or if their parts are replaced."

I performed a running Lamda test and mine drifts outside their green lines constantly. Their green range is 200-600 millivolts and the TWO Lamda sensors (one Lamda for two cylinders so you have two) were running 100 to 700 on mine. Two bars, a red and a blue for each lamda sensor, just dancing up and down through their green median. Dunno.

When you click on Service Date it will launch a window telling you you have only 10 VIN possibilities to use and do you want this VIN as one of them? Selecting YES kicks you to the Change Date and Mileage Screen which now unlocks for that VIN bike. Mine said next service was 5-11-2011 and/or at 8,000 miles.

No fault codes were found anywhere and I was hoping to see one as I had a very strange shutdown in traffic today where the only way to get the bike to start was to turn the key off and on, hence rebooting the computer. The starter switch was just dead to anything but a key cycle (kickstand up/down, clutch in/out, and Neutral with a 'No Start' on any?). I dunno what happened, other than it did take a lot of gas 3.6 gallons so maybe it ran dry while stopping?

Hope this doesn't become one of those haunted right switch things like what happened on their K1300GT line and resulted in a recall.

Hey Mack, I've got the BT version as well... although I only got it in anticipation of hooking to my Blackberry whenever they get that figured out. So far I've just used the USB to the bike and it seems to work fine. Don't recall the injector test too much, but seem to recall I didn't hear any clicking either. I've got the O2 sensors unplugged on mine due to having the PCV installed on the bike and it throws a code for each. Nothing on the dash, just a code on the GS-911. I also have one for the fact that I have the rear valve (exhaust) unhooked. Again, nothing on the dash, just something on the ECU that has to be read by a computer (or GS-911). The servo test seemed to work fine... you could hear it operating the servo and re-calibrating it. I primarily bought it for resetting the service light and mileage till next service. It's a great little tool to have in the toolbox.

there are eight injectors - four in the throttle bodies and four mounted in the top of the air box.

Good to know, just I never heard the clicks off the 1-4 injectors they showed so that puzzled me - and Max's parts count of 4 too. Injectors 5-8 definitely clicked a few times each with the key on.

From their parts list on Max site, it only says 4 injectors for the total, but when I look at their exploded rat's nest diagram, I can see 8. Looks like 4 rails with 2 injectors each in the diagram. Then again, their parts list only says 1 rail too (?). Whoever did the tally of that part list is off a bit on quantities.

Here's a better diagram:

Looks to have a full pressure rail on top, and a pressure controlled rail at the bottom. Don't know why I don't hear clicks off the upper rail with the GS-911 if that's injectors 1-4 in the GS-911 program?

Back on the GS-911, I never heard the click of the tank vent solenoid either. Didn't try it with the tank filler open if that's a requirement? Both Lamdas (if it has two because I saw two lines?) were outside their upper and lower green zone too by 100 millivollts. Surely they both cannot be gummed or varnished up in only 1,800 miles? Possible, I guess.

Hi Mack,

I've had the GS-911 for about 3 years and use the BT between my BlackBerry and the GS-911 on my GT, don't you?

I'm not an BT or a phone electronics geek, but I know 2 things: 1) the BB version of the mobile SW doesn't have the S1K on it yet (Still hoping for soon), and 2) I've never had any luck between the BT on my laptop and the BT on the GS-911. I don't think the PC app supports BT, the PC version is only meant for USB. I think it's the very specific mobile device java interface that the PC app wouldn't be using.

My PC connection results were similar. I couldn't hear the injectors and I couldn't hear the Tank vent - but it probably has to do with the external conditions (or my ancient hearing).

As for the Lamba sensors, did you have the bike fully warmed up? There is a lot of discussion on the GS-911 forum and advise from Stephan at GS-911 that these sensors don't work (aren't actuated) until some temperture level is reached. I da know.

You should use their HelpDesk or the Forum for asking how the device works and how for each test. I do all the time (even though the forum is inundated with air-head beemer dudes from around the world trying to fix their ancient broken down bikes).

You obviously bought the "non-Pro" version of the device. Yes, it keeps track of up to 10 different BMW's you can connect to it for diagnostic purposes. They keep track, and after 10 different VINs are attached, you can't perform certain "reset" functions - like service date/ milage, untill you pay another c-note and get registered as a "pro".

As you have learned, the GS-911 only reads codes held in the ECU, and just because you had a stall (or ran out of gas?) there is not necessarily a "fault code" for everything that can happen, like "you dummy - you ran out of gas". Your engine kill does sound strange, but I wouldn't get paranoyed about the switch-gear on this bike - yet.

Hope this helps some.
