Camshaft sensor readings on F800GS & WTF

<< < (2/2)

WayneC:
No manual will assist in interpreting real time data it is the province of the pro mechanic and they struggle at times, we are all learning

What I do see in the data is a difference in knock sensor readings between cylinders which would suggest an imbalance and poor combustion on one cylinder

You can read a little on the basics here

Re ignition angle these machines use variable ignition timing speed/load dependent and the info is showing it is working

Re camshaft sensors, some machines use 2 sensors, a crank sensor and a cam sensor to determine ignition timing others like the 650GS use one sensor.

Interesting you would provide a link to an outside vendor. That website also provides no explanation of specifications, as in 'this product measures misfire in readings from 0 to a maximum 500. Consistent measurements of +/- 50 away from normal indicates a knock (misfire)'.

Its kind of a nifty toy that we are still guessing its purpose and mysterious uses!

Effisland, I get the impression that you are expecting the GS911 to act as a magic wand on your bike, telling you exactly what is wrong, why it is wrong and how to rectify it.

Sorry to disappoint you, but, that's not going to happen.

As WayneC has tried to explain, the GS911 can only reflect the error codes the ECU/BMS has stored.  These are all set by BMW, internally in your bike's ecu and NOT the GS911.

If you have a mechanical problem such as a broken piston ring or bent valve, the GS911 has no way of "seeing" this.  Similarly, the GS911 has no way of determining whether a spark plug is dead or not.  It will also not be able to tell you whether the injector is blocked.  Some level of mechanical expertise is required in conjunction with the use of the GS911 as is some knowledge of how the sensors function (as in the link WayneC posted). 

The readings from the GS911 can give us a clue as to what might possibly be wrong.  For example, a cylinder that's temperature is very much different from the other cylinder could point to a cylinder that is running too lean,  Yes, that could indicate a blocked injector, but the muck in the injector cannot and will not generate an error code for you to see with the GS911.  It could also indicate that you have a blown head gasket, but again, a blown head gasket doesn't generate an error code.

Yes, it is interesting that WayneC posted a link to an outside vendor.  It is just as interesting to note that none of the sensors on your BMW are made by BMW.  They are all sourced from companies that actually manufacture sensors.

The same can be said for your brakes.  They will most likely be Brembo Brakes, as found on BMW, KTM, Honda, Suzuki etc etc.  Just because it is on your BMW doesn't mean it was made by BMW, but, I degress ....

It would be far more useful if you plotted the values you have presented in chart form.

For example, it is very difficult to see whether your lambda sensor is working from the chart you have posted.  It is much easier to see it like this:



As for the codes and what they mean, you will have to contact BMW for that.

Have you done a compression test on the motor? 
Have you done a leak down test on the motor? 
Have you checked valve clearances?

If so, what were the results?
