I've had the PCV and Auto Tune on the bike for 5-6 years and I haven't touched it except to install a couple maps and accept one AT adjustment. Never used my LCD-200 yet. This stuff is so complex if you really want to get into it that I doubt many people even are aware of what they can do with there PCV. I had to call DJ ytech support 4 times yesterday. Last time, I heard a lengthy sigh before the guy said, "Hello, Dyno Jet technical support, can i have your name please.....same spelling as the last time you called?" LOL Sorry, I paid enough $$ for all these gadgets and I do intend to figure out every last thing that they do.
I'm going through the PCV with a fine tooth comb right now and will do a write up that covers everything step by step. It's too bad there are not more people using PCVs these days but I do see why part of the reason for favoring a flash is the simplicity. Hopefully we won't loose sight of the value of products like the Power Commander, Auto Tune and Ignition Module. I'm diving into it.
