Good morning all,
Would really appreciate a second opinion or real world experience of this fault........2014 1200 multistrada, went for morning ride,all good,stopped for bacon roll,started bike,revs went to approx 3,500 then settled after about 20 seconds to a lumpier than usual idle,upon trying to pull away it was like the throttle wasn't connected to anything, no rev increase and some pops,switched off and on again then it idles properly but still fluffy at very small throttle openings. No codes on dash ???? Possible map sensor?? Thanks all andy
 
Nah then Andy, welcome to the flock, I'm sure your gen two mutly would have given you an EML if the ecu sensed a fault with the MAP sensor.
Without diagnostics always fun to fault find, I've had 2 mutly's and not had that particular problem.
Someone who is wiser in the ways of the force will hopefully be able to help.

I had something similar with my 2011 Multi 1200 during the summer. Sadly I didn`t even get to have a bacon roll , just an overdone Greggs sausage roll at a filling station. Life can be so cruel sometimes.

The bike symptoms you describe were almost exactly the same and yes it was the map sensor.

Great,thank you very much
 
The map sensors seem to fail in one of two ways. An electrical failure will raise an error flag and is easily traced. In this scenario, the bike tends to run ok, sometimes a bit awkward to start, but because the ecu sees the error, it takes data from the other map sensor and applies it to compensate for the failed sensor.
The other way, there is no error flag, but viewing the live data with engine running, it’s obvious that the sensor is reading incorrectly. The ecu isn’t aware of a problem so there’s no compensation applied. The motor definitely runs worse with this failure. The obscure data causes fuelling changes that usually result in excessive fuel trimming.
