Yeah I use 2 sensors to detect up or down shift then the neutral light to show an 'n' on the display.
The whole thing is a bit of a novelty and just a project for me to play with arduino and coding, so the odd missed gear messing it up until I reach 6th or neutral isn't a big deal to me.
The cleanest method I've seen was on the TDMs as they use a nylon disc on the spindle which you can wire contacts to, so the actual gear location can be truly indicated. I'm not sure of the fazer has the same fitting so will be looking for one as my next project if it does.
