I don't entirely understand what Nate can and can't control on the ECU, but I think the other thing that Nate's new numbers for my car tell us is that to have maximum performance in Reno, there must be room in the maps, or whatever to allow the ECU to take advantage of the lower air density, at minimum by advancing timing further.

Does that sound right?

I have no idea if the ECU knows anything about altitude, or air density.

Nate, Help... I'm over my head, but for us altitude folks, it is an important issue. We want as much power in Reno, or at 7000+ feet even as possible without blowing up our cars when we go to Sac, or SF for the weekend.
