Anyone tried running nearly all +4's in the ignition on a tuner map. I tried this map and it seemed to give the bike a lot of pep in my 2016 WR450. I could imagine the previous fuel injected WR might start with a similar advance and then + to a similar finished advance when at +4. It doesn't seem as if there is any pinging at all. I'm not sure if Yamaha would design the tuner to put too much advance in the bike.
Note: Obviously I am running premium fuel but straight from the pump and there is some fuel + in there. So far I have only tested it for 9 miles or so in Rower flats where there is a slightly rocky at times uphill loop trail.
