The hard map is switched by joining the map wires together, and the soft map by disconnecting them. If the OEM map switch is wired in, position 1 joins the circuit for a hard map, and position 2 breaks the circuit for a soft map. I have tested and verified this with a test meter.
The difference between the two maps is very subtle, and in a lot of cases undetectable. I find the bike seems to hook up better on very slippery stuff with the soft map, although the bike seems to ride exactly the same.
I would say that anyone who is experiencing a massive difference, or seeing higher power on map 2 is imagining it. A double blind test is required - A freind randomly sets the mapping to 1 or 2, (toss a coin, heads 1, tails 2) then tapes over the switch. You then ride the bike, and try to guess which map its on. Repeat 10 - 20 times, then study results. if the difference in mapping is clear, you should be right 100% of the time.
I remember reading once, the any power differences less than around 10% cannot be reliably detected by seat of pants methods.
Ps, the mapping on my old FI TE450 was very noticeable - the soft map just cut out the upper revs power band, I would say around a 25% loss of torque / power. I never used it, as if I wanted it to ride calmly, I used lower revs, where there was no noticeable effect with the mapping anyway.
