From The Stix 2 Da Brix
If I tune on a hot day say 98 with 98% humidity will it affect numbers if I tuned on same dyno at 65 with 20% humidity? If so explain as I don't quite understand.
That's odd, the IAT and MAP sensor on the Raptor should account for a change like that. And you would be suprised how a dry 85+ day can be close to a 65 humid day in air density, since the more humid the day the less air you're getting into your intake charge.... Now your bike has me pondering :lol:Spider unfortunately the weather does change the performance and A/F. I had tuned my rappy near perfect via the sparkplug when the weather was dry and hot (85 or hotter) and when I went out on a 65 degree humid day the plug came out black after the ride. I guess the only remedy would be an auto-tune.
