- June 09, 2011, 15:04:57 PMI have a Power Commander III that I no longer need. I had it Dyno'd in when I put on my Thunder Mfg teardrop intake and my Bub long pipes, I have the CD's with all the Dyno information and mapping that resulted from the Dyno work. They dyno work alone cost $400.00

- June 09, 2011, 12:44:18 PMQuote from: 1SG CAV on June 07, 2011, 22:54:43 PMThe Powercommander website only shows 2 Vance & Hines downloads. One with and one without baffles. Nothing with the Thunderbox. Are you suggesting I use the download for the Hard Krome exhaust?Hey I know your problem. I have a PC III and a hyper-charger on my 02 1500. You can go to power commander web site and down load the map for Vance Hines without baffles and Thunderbox. This is the map I use on my bike. The thunder box is the components between the hyper-charger an the throttle body. With this map My bike runs great. Dyno the bike is truly the way to go. Hear in Oregon it cost me $250.00 Vance Hines is the closest thing I can come to for pipes. I have Hard Krome two walled headers (straight pipe) on my bike. You can do mild adjustments yourself. I will tell you that if it starts to run like crap. first check for broken wires. dailed in you'll like the way it rides.

Dyno looks like an even better idea... to me anyway!

- June 07, 2011, 09:28:22 AMI love puzzles....I just had a thought. Inside the stock airbox, on the right side, is a small sensor, the A.I.T. sensor. I don't know if this sensor is present in the air intake you have...but it could be crucial to the operation of the system. It senses the incoming air charge temp. and makes fuel adjustments based on it. Normally, the fuel trim would be richer in 50 deg. weather than in 90 deg. weather. There are also 2 idle air solenoids in the airbox. If those are not functioning correctly, or leaking, that too would enrich the mixture. Just some idle thoughts... I really have to get a life...

- June 06, 2011, 16:57:44 PMSince the day I got the bike the mileage has always be off. When I first got the bike my range to empty was about 125 miles. Since pulling the baffles the mileage dropped to 85-90 per tank. Either the initial download was wrong or you might be on to something.
I am calling a few local shops to get pricing on having the bike dyno'd.

- June 06, 2011, 16:38:37 PMSomebody either installed the wrong map for your bike, or there is another problem, like....and I've seen this on cars, a lot...the fuel pressure regulator diaphragm has a small hole in it and fuel is being sucked through the vacuum hose. I would start by installing the zero map, which takes the pc III out of the fuel control picture and lets the factory programming proceed. Does this thing smoke under load? Are the pipes sooty? Check the air filter in the box, since it's open to the "ram effect" maybe it's plugged with dead bugs and other debris

- June 06, 2011, 16:34:17 PMFirst, any of the boxes have to be adjusted based upon your pipes and breather. The Dyno is the most effective way of doing that... as has been noted, anything else is guesswork.
I have a cobra box on mine... the box is set up for the bike and pipes used. You can then adjust it for variances in that setup. A dyno can also be used to adjust. Not all pipes have the same impact on the bike. Different pipes impact the FI in different ways.
You are getting terrible fuel mileage, but you made that decision when you removed the baffles and kept the hypercharger. Since you have the pcIII have it dyno'd. You might improve mpg's enough to pay for the dyno in a season or two.

- June 06, 2011, 16:25:45 PMI cant complain about the performance of my bike. It had all that stuff when I bought it. I pulled the baffles because I like it a touch louder. My beef is the awful gas mileage. I hit empty at around 85 miles. Maybe 90 when I'm only on the parkway. I wouldnt consider myself heavy on the throttle. But this stinks.
I would agree that playing with the settings on my own is hit or miss. I just hate spending the money to have the bike dyno'd.

- June 06, 2011, 14:49:12 PMI 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

- June 06, 2011, 14:35:54 PMI 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....

- June 06, 2011, 13:16:01 PMMy 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
