I just went out and tried using the open/closed gauge and for the other three I used Horsepower, Gallons Per Hour, and MPG. Using that combination I went onto a 50 mph road and floored it from 0 mph (which doesn't mean much in an R18 auto, haha) This time everything worked fine. wtf. I'm happy it works, but it's weird.
I also tested it from a 30 mph roll and it worked as well. No more 9999 mpg and 0.0 HP and the GPH was still reading and didn't go to 0.
It worked when it was closed and when it was open. Highest HP I hit this time was 128 hp.
