I recently purchased a power commander, and finally got it to power up using a 9V battery. I downloaded a map from the power commander website, for a completely stock 2005 Ultra Classic. I installed it today before a 100 mile ride, just to see if there was a difference. Now unless I am imagining it, there was a markable increase in throttle response, idle was smoother and top end performance seemed to increase. I noticed at 70 mph the rpm was around 2800 where it normally is 3100 or so. It also seemed the bike pulled a lot harder(had 26H Andrews cams installed earlier this summer)and did not bog down when the rpms got down around 2000. Can't wait until I get the new air cleaner and true duals on to see what happens...Also noticed my gas mileage dropped, but that could have been from the several 80 mph(twice over 105) speed spurts...LOL

You are going to find exactly what you did. Better running everywhere, gas mileage down this can be controlled to a point by a good tuner or even Dynojet Auto Tune that I run, cooler running, and just wait when you get some air moving through her you will really wake her up with your cams and PCV already in. Sounds good make sure to get the right maps from Jamie rather than cans from Dynojet some are good for some conditions don't get me wrong but Jamie's will be much closer to right on.

 

I'm REALLY confused by the 300 rpm drop. In my world you need to make a gear change for that to happen.

 

The map you loaded was for a stock UC so it should have been a wash. The "stock" map must change some things then?

 

science- rpm is rpm

tuning can't change that, either instrument or operator error

Thought you could just hook it up to the PC without any external power?

 

If its on the bike

 

Like I said, I am not sure why either. I know when running 70 mph, in the past the tach read 3,000-3,100. When I hit 70 today, it was showing 2800-2900. Could be a tach error, could be my eyes were tearing from joy, or could be the fact the bike was running so good, it didn't take 3100 rpm's to get to 70. Just made me happy with the performance.
And I figure the stock download from Dynojet did have some changes in it, cause a lot of things were a little different...

Like the other member said, if it is on the bike, then no external power needed. But I don't have a laptop, so there is a 9V adapter that plugs in and will power it up, long enough for the pc to find and recognize it and download the map. Has to be a new 9v battery, cause it takes 8.2 or so volts to get it powered up, according to Dynojet..
