Power Commander fuel maps

I know that a few of you have installed the Power Commander and I wanted to find out what fuel maps other people were running. I have the K&N air filter in a drilled air box, the Leo Vince Exhaust, and I plan to install Dr. Pulley 26 gram sliders next week. I live at over 5,500 feet above sea level , so I am wondering if anyone else has ever developed a map that would work well for me, or if I will need to pay to put the bike on a dyno to get the best results. Any suggestions?

When I had my Power Commander mapped from a certified tuning center, he warned that my map should not be used in higher elevations. As I recall, he said around ~6000 feet.

Check with a certified tuning center in your area and ask them the same question, which they should know based on your elevation. If this is true, I would not use other customized Power Commander maps ... though if you travel to lower elevations you could switch maps.

I don't know of anyone that has mapped their wing for high altitude.
Even so, someone else's map will only be a ballpark as every bike is
unique. If its not a financial hardship to have your bike mapped, I
suggest you do it for a perfect result.

Thanks for your insight. That is pretty much what I was thinking. I have an appointment set up for next Friday with a local Dyno shop to get the PC dialed in and install the 26g Dr Pulley sliders. I am anxious to see what this will do to enhance the 0 to 60 accelleration. Whatever map the PC is set on right now really sucks. There is no power from 3500 rmps to about 6000. Then it starts to run OK. I will let you know how it turns out.

Sounds like you've already installed the PC...

BELOW IS EDITED TO TAKE IN TO ACCOUNT BILL'S COMMENT IN THE NEXT POST: (Thanks Bill)
If you can get them to do it, have the dyno shop do 5 test runs:
1. PC installed (Factory map)
2. PC installed (Zero map) =to not having PC installed.
3. w/PC and Dr. Pulley sliders in (Zero map)
4. w/PC and Dr. Pulley sliders in (Factory map)
5. w/PC and Dr. Pulley sliders in (Custom Map)

I assume you are using the USB version of the PC?
They can also lay all five graphs on the same sheet for a comparison.
Bring a USB drive with you so they can give you all the data on USB,
all maps and graphs.

Then you can post your graph results here in your album and share your map as you see fit. You will also be able to make minor adjustments from
your map on your home computer and reprogram your PC yourself via
its usb port. Maybe a summer and a winter map.

If I'm not mistaken, you can just unplug the PC to get back to stock, right?

Or use the Zero map.

Last Friday I took my bike in to the shop to have the 26 g sliders installed and have the power commander dynotuned for my altitude. The changes are noticable. The engine runs significantly smoother and it feels "cleaner/crisper". When I open the throttle, the sliders readily boost the engine rpms to about 5500 and there is a noticable improvement in accelleration over the stock set up. It is not as quick as the J Costa was, but it is decent and my gas mileage is still in the 56 mpg range.

The dyno chart indicates that the maximum horsepower is a bit over 36 hp at 6400 rpms (90 mph). Peak torque is 30.5 lb/ft at 4300 rpms (57 mph), but the torque curve is very flat (28.5 lb/ft to 30.5 lb/ft) from 3200 rpms (35mph) to 6100 rpms (85 mph), so the power delivery is steady and strong through that entire range, which is great for passing.

These numbers are not as impressive as those I have seen from dynotests on Silverwings at sea level, but from what I have heard we experience at least a 15% to 18% drop in horsepower due to our altitude.

Someone was talking about installing 21 g sliders. I would be interested in hearing feed back from you concerning the performance and gas mileage that you are getting if you don't mind sharing your experience. Thanks.

What was your hp number before this upgrade?

Dan

Dan:
The maximum pre-tune horsepower was 29.37.

Are you sure? That's a 25% increase!
I guess the altitude makes a huge difference.

Well, technically it was a 22.8% increase. But yes, I am sure that is what was reported on my dyno chart.

When flying with a naturally aspirated piston engine the rule of thumb is that at 7500' ASL there's a 25% horsepower loss due to the thinner air so the numbers above sound about right.

There was one more piece of information on my dyno chart that I found interesting. They reported my speed (as measured by the dyno) at the various hp and torque measurements. The top speed shown on the chart was 114 mph. I am assuming that this would be actual. However, I doubt the bike would be able to reach that speed out on the road due to wind resistance.

I have been over 100 with a stock bike (aside from a shorty windscreen and K&N filter. The bike still seemed to have plenty of pep at that speed, so I wouldn't be too confident it wouldn't make 114.

Maybe so toolbox.
I had my 2007 up to an indicated speed of 113 mpg and it still had juice left. I may have to test out my 2009 to see what its got.
