TE/TC Decoding Map Switch Position

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.

So I may be correct?

Yes, how you describe it is as it should be - very subtley calmer on map 2

Oh man im still in doubt (no offense) to whats what haha, the testemonies are always back and forth. Nice to hear you got bike dialed in though

OK my 1st post (coming over from the 'orange side' w/ a shiny new '16 TE300. Re: the OEM map swich that is integral to the front brake master cylinder; since the documentation that came with the bike brand new 48 hours ago did not cover this I decided to figure it out for myself scientifically. the manual does mention that the black and the gray wire, that when plugged together (i.d. closed circuit) invokes the performance curve. Unplugged (i.e. open circuit) invokes the non-aggressive curve. I then broke out the Fluke 87-V multimeter set to 'ohms' and checked the continuity across the actual wiring going to the switch. Pos'n I = continuity (closed circuit). Pos'n II = no continuity (open circuit), so....putting two and two together we find that position 1 = performance and position 2 = non-aggressive. That was easy wasn't it!!!

Welcome and enjoy the new 300! I sure am.

This thread is 2 stroke related so no switch under seat. Only the plug under the tank.

And that's exactly how I tested and proved it!

Could be just me but tried both thos weekend (shutting off to switch between) and 1 seamed less radacle than 2, hmmm
