Power Commander III Installation

I recently purchased a PC III from a member here. Installation I am assuming is pretty straightforward. I'm looking for manuals on the internet. I don't have any mods right now, and will be running the Zero map for the time being. I've read mixed reviews that the Zero map smooths throttle response. Luckily I have a windows PC laying around, as my daily driver is a Mac.

If you have a PC, let me have any recommendations and advice for getting the most out of it whether or not you have mods. Eventually I'll be doing slip-ons and a decat and may alter the fueling at that time.

My $0.02, I wouldn't install it. Over the years we've seen all sorts of engine trouble, including a blown engine from a lean mixture, from the Power Commander. A slip-on doesn't require any remapping, and a cat delete can be handled with the on-board fuel-trim tools that Yamaha has installed in the ECU. Throttle smoothness happens at the wrist first...software second.

Interesting... I hadn't heard any of this. I have become accustomed to the twitchy throttle so that is less of a concern now.

I've always been under the impression that most bikes come lean from the factory, especially in the mid-range, and that increasing airflow even a little bit should coincide with an increase in fuel. I know that the PC isn't the only way to do this, and it isn't totally necessary, but I also hadn't heard of issues. Of course I wasn't specifically looking for problems people have had.
