You should check the earth connection to the ECU. If this is poor it will affect the voltages the ECU is seeing and can cause all sorts of errors....

Yes, I had the same problem. I tried all that you have done and ended up cutting the bolt out with a reciprocating saw. Details are in this thread...
Yes, I went through all that on my 2010. I ended up cutting the bottom bolt out with a reciprocal saw. Details are in this thread about 2/3 down...
There appears to be two wiring versions. Early bikes up to 1998 have a single wire neutral switch. The neutral switch and the oil pressure light...
