Just checked and corrected my '18 1000's TPS today.
A question was asked in this thread if the '18 is the same as the '14 thru '16- yes, my '18 was the same procedure as the 14-16.
My TPS was set at _c. I readjusted to -c and put it all back together. If everything goes well, this should be a half hour job. (My bike took about an hour- see my note #2 below)
A few notes-
1. You only need to lift, and not remove, the tank to access the adjustment screw. The gas tank lift adn remove procedure is in the owners manual.
2. I had a problem with the two chrome plated screws on top of the tank which hold the left & right "beak" side covers. Upon reassembly, neither of these screws wanted to thread back into the flimsy support bracket. I needed to re-tap both threads of the support bracket before the screws would thread up. (maybe extra zinc plating on the threads?) These require an M6x1.0 size tap, if you want to buy a tap.
3. You'll likely have a contraption of sockets and extensions to get the Torx safety bit to the adjustment screw. Be sure to wrap some electrical tape around these tools to secure them together so that these tools don't drop into the wiring harness.
4. The test plug is found under the RH rear of the seat. Not sure if this is the same as the older bikes.
Results- A very big improvement- VERY big. The overly snappy throttle is gone. The lower rpm powerband is now much smoother, with none of the previous ON/OFF throttle response. The bike is easier to ride in every gear. I'd strongly recommend for everybody to check their bike's setting.
A great big thank you to everyone who contributed to this thread. I very much appreciate your sharing the information.
