Power Commander for 2003?

I'm about to buy a 2003 (US model), and while day-dreaming about mods I've found that DynoJet lists a Power Commander for only 04-08. I've tried looking at part numbers for the fuel injection unit, wiring harness, etc, but haven't been able to determine what the difference is. Does anyone know why the PC won't work in the 02-03s?

Mine is a 2003 Works just fine with it.
Use the Powercommander III USB.

Yep same for me in UK...... My Swing is also a 2003 model....

Hey Edbancro,

Same here. I have a 2003 also and have no problems whatsoever with my Power Commander. It should work fine for you.

Ok. I am seriously thinking about putting a power commander on my Swing. Can those of you who have all ready done so give me an idea of the benefits of a power commander. I know what the manufacturer literature says, but I want your real world opinions. More power? smoother? better fuel economy? how much?? Thanks...

Well, you already have the exhaust and variator. The PC (with a custom map for your bike) completes the necessary trifecta for as much power out of the bike as you can get without turbocharging or nitrous.

The three together give you about a 15% increase in rear wheel HP, and a smoother and wider power curve, and proper fuel/air ratio across the board.

Somewhere on the other board I posted my dynojet test results. Suffice it to say it is a worthwhile investment.

Dan:
I think I have looked at your dyno results and they were very impressive. In addition to the power I am also hoping to improve my fuel economy. If you keep your rmps in the 5,000 range what sort of mpg do you get?

Fuel Economy? What's that?

No, seriously. I ride two speeds:
1. The speed of the person in my way, or
2. "balls to the wall".

Also, my bike has a serious aerodynamic problem (in addition to me), and alot of extra weight. I couldn't give you accurate mpg info if I tried.

Dan,

I thought you only had one speed .... I'll let you guess which one.

Bill,
Other people have every right to take their time.

They have no right to take MY time, and that's what they do when they're in my way!

They don't allow lane splitting in Florida.

Have you done a search on the forum here...... This thread should give you some intersting reading, and there are a few others...

As I understand, most bikes fitted with a power commander (PC) can on average make up to 5-10% increase in bhp and better torque, IF they have a decent map... The best map is one that is made specifically for a particular bike on a rolling road or dynamometer...... Given that the S'wing isn't exactly a powerhouse, a PC on its own is not going to make a huge difference in power..... But it will make a big difference in fuel economy, engine response and smoothness.... Really it is quite sublime, and noticeable... But might not appeal to all... read this thread, which also gives you a few figures and comparisons....

Aswell as giving the best fuel air mixture at any given revs, the PC can be specifically tweaked to optimize / boost different areas of your power band.... Like for example I saw a weird 3 position switch on this fellas track bike, on the left handlebar very close to where his left thumb woud be..... It was for low, medium, and high areas in the powerband and simply switched between 3 different PC maps whilst on the fly... But that bike delivered something like 150bhp plus at the back wheel.....!

However as Dan has mentioned if you have already fitted a new exhaust and sports variator, then the PC really is like the icing on the cake in that it makes the most of all the other improvements and essentially maintains your bike in a great state of tune

The fella that dynoed my S'wing said that a 20% increase in bhp is a very good result, among the best he has seen ... But the real bonus was if the stock figures are anything to go by, the 30% improvement in torque..... (but don't forget, this includes the variator and exhaust mods...) My 0-60 time was about 7.5 seconds and is now nearer 6, which is a significant improvement especially around town and it sure helps brighten up those boring commuting runs

And finally, if you were to take things easy, accelerate gently then you could expect an mpg in the 60s... I managed 59 I think as my best, sticking to speed limits and going easy in town, but it is incredibly hard to ride like that as with the performance mods the S'wing just begs for that throttle to be opened a bit more than you need... Thus I tend to get the high 50s on longer trips on the open road, but as a lot of my riding is in urban areas I tend to get high forties, occasionally low fifties.

Hope this helps...... Have fun

Bernardo and All:
Thanks for sharing your experiences with the PC. My initial motivation was to try to get my fuel economy back into the mid 50's, but now having read the comprehensive discussion provided by Bernardo, I would probably put on a PC just to boost the performance even if it ended up lowering my fuel economy! It sounds like a very nice modification. So, this Christmas I think I may just end up getting myself a PC and heated grips... Oh boy!

I sure appreciate all the advice and information you guys provide, but my wife says you guys are very expensive... I guess you can't please everyone...

She should be happy we don't charge as consultants.

Very funny Dan - I will be sure to point that out to her...

Glad to help

And don't forget that ultimately the PC will help save on fuel cost!!! even if it takes a year or so to recoup the cost of it, and the dyno tuning....!

You can bet that I will be sure to point that out as well Bernardo...
