I have to say that unless you put it on a dyno and tune it you will not get the most out of it. If you go to a tuner that has been certified in tuning them he will have the ability to let the computer that is attached to the dyno make all the changes to optimize the PCIII. It walks them through about 20 mins of instructions where the tuner accerates, holds the throttle at certain RPMs and some full throttle pulls to get the A/F ratio where it needs to be. I only gained about 2hp but the throttle is way more smooth and crisp it was worth the $175.

Sharing maps isn't the best idea - ESPECIALLY if the maps are custom tunes for specific motorcycles. There are too many variables. Just because one guy's works well for him, doesn't mean it'll work well on your bike.

Use the stock maps available from Dynojet (they are conservative enough to be "shared"), or get yours tuned by a professional. A lot of people can attest that it is definitely worth the $200-300 investment. Besides, if you don't, what's the point of having a $250 Power Commander in the first place? It isn't doing you any more good without a sufficient tune.

this is my map if anyone wants to look at it for research purposes.
this is a custom tune for my 2001 with a d&d slipon and k&n air filter
accel pump is disabled
my bike ran EXTREMELY rich before this tune so that will explain alot of the negative's in fuel

actually I finally got around to checking out your custom tuned map.. and it's somewhat similar to the one I'm doing right now. There are differences though where the swap from more to less gas occurs. It just goes to show that there's no way.. those refab maps are optimal at all. A change of +/- 5 gas is decently significant. And we vary more than that sometimes. I'm also tuning off real driving data.. but I have no clue whether they used a variable fan to push air in.

Anyways: With rather similar mods..

at closer to WOT areas I'm adding most around 3k-4.5k then it scales down. decrease from 7k-9500. Then it's merely slight increases till topping out.

What I'm tuning to is around 12.8-13.2 at WOT. TPS 40% and under is from 13.5 - 14.

The awkward part is that I don't have any double digit decreases in gas at WOT. After I'm done I'll probably DYNO again and compare to my zero map..

I feel like the numbers will be slightly inaccurate though because at WOT.. I can see major differences between 1st and 2nd gear. Obviously the engine gets more air shoved in at 80 mph than 40 mph.
