I have an 04' Rubicon and have had it in the low 50's with a little left in it. I've been told they get close to 60 but havent had enough road and nerve to go all out yet. As for the D1 - D2, D1 is your riding setting, called the performance selection it allows the trans to shift later for better performance. D2 is the Torque Mode - or as they say "Use on minimum traction situations". What I find different is the shifting point is different for the auto trans. And of course ESP is for the manual/electronic shifting. Best place to view pix is the honda website 05' - 07' have the same body styles, colors vary by year. Here is the link:
