Power Commander

Is this a race? I'll have to use my W-650, it's quicker than the Drifter...and much to his surprise, a guy on a very loud 103 inch RoadGlide.......

I have a PCIII on my 99. One of the short comings of the PC, and any premapped type system, is you really need a Dyno and a guy who knows how to use it to it dialed in. Doing it any other way is just guess work, might be better, might make it worst. All adjustments are handled through the software that came with the Power Commander.

Guys have had problems with the Hypercharger on Drifters, some have fought through itand get them to work, other have just gotten to the point where the get rid of the Hypercharger. Not much help, I realize, but if you decide to mod the PC III settings be sure to save the original one in it so if all goes bad at least you can always get back to where you started. The PC III website has several differant setups. You could possibly try several of them to see if you get any improvements.

Just as a note: I have never gotten anywhere near the mileage claimed by some. My riding style and terrain possibly play a large part in that.

Again Troll!! I just got to start typing faster

I was looking into installing somebody's aftermarket fuel tuner, too. I wrote to Cobra, since they seem to make the most reasonably priced one, and they told me that theirs, and indeed, everyone else's just ADD FUEL to the existing map. I looked at the power commander fuel maps and the rpm range they address, and the area I need to tweak is not accessible by anybody due to emission control rules. If you download and install the zero map, that is the basic factory setting, and it makes a power commander a pretty expensive piece of cargo. Any other map will just add fuel above 3000 rpm. Not much of a help. By pulling out the baffles, you decreased back pressure and noise level, and increased air flow through the engine, thereby lowering intake manifold vacuum. The higher the manifold vacuum, the efficiently and economically it runs. The MAP sensor sends signals back to the computer that tell it what kind of load it's experiencing. The heavier the load, the lower the vacuum, the richer it runs.  I just got back from a 400 mile one day ride, and keeping speeds to about 62 mph, I got 42. something MPG. My speedo is off exactly 2 mph over the whole range, so 62=60 real world mph. Just no way to really "re-jet" fuel injection....

My 99 Drifter has a PowerCommander III along with Vance & Hines Longshots with a Kuryackn Hypercharger. I bought the bike this way. The bike never really got great gas mileage and since I pulled the baffles it has gotten worse. The PowerCommander website has a map for my bike but with a stock intake.
Would I need to make a change to this map to allow for the hypercharger or is the baffle removal more of an impact?
I must assume that once I download the new map my fuel consumption will improve. I also have occasional backfire. This I dont know if a download will fix. I know that fuel can be adjusted for each range directly on the powercommander but not sure what adjustments to make.

Thoughts?

Thanks
