What does the power commander do? How does it work? What are the benefits.

Can my bike benefit from it? or will I lose performance due to the air system that has been engineered for this particular model?

How much Robert DINERO?

Below is the test, and specs for this bike.



ZX-11's ram air is a closed system: The front inlet duct is the only source of incoming air to the airbox. This sealed system accomplishes two things: First, it creates a ram effect that pressurizes the fuel mixture through the carb throats, and increases intake velocity. Second, it provides a steady diet of cool, dense air by completely isolating the carbs from engine-heated air.

Airbox ducting alone creates a pressure rise in the carb throats only; without also increasing float bowl pressure, the engine would merely lean out and run poorly as pressure in the throats increased. Early reports had the ZX-11 fitted with an electronic fuel-management system, but Kawasaki engineers found a far simpler -and lest costly- solution: They vented the bowls to the incoming air source -the mouth of the duct- through a tube that boosts bowl pressure as airspeed and intake velocity increases.

Drawing cool, dense air into the engine increase power across the board. But because the intake pressure created by the ram-air system is governed largely by incoming airspeed, the ZX-11 must be moving at high speeds before the system has a significant effect on power. The Kerker dyno, equipped with two-speed cooling fans rated at 45 and 85 mph, showed the effect of airspeed on the ZX-11's power.

With the fans at 45 mph, the ZX-11 ran as much as three horsepower stronger from 3500 to 7000 rpm than with the fans at 85. Conversely, the 85-mph head wind created a boost in power from 8500 all the way to 11,000 rpm, where the ZX again ran three horsepower stronger. Obviously, Kawasaki calibrated the system carefully: The ZX makes its biggest low-end and midrange numbers at low road speed, while high-speed running nets the biggest top-end numbers. Judging by the ZX-11's 175-mph top speed, we suspect the ram-air system may pay even greater power dividends at ultrahigh speeds.

rrrright. You go get your powercommander for your 92 ZX11...

Pick me up some muffler bearings when you're there.

that's almost as crazy as the guy that asked my buddy if he had a jet pack on his fuel injected R1

What genius! Brilliant observation, watson! Ram air, the future of motorcycling!

I had to double check the date to make sure this wasnt posted in the SRAD days...

While the information posted about the Kawasaki and the sealed airbox is correct, I still don't understand the meaning behind this post.

stream of consciousness, disjointed thoughts. The cut and paste article is jurassic in sportbike years and doesnt fit or frame the question at all.

dunno.

Assuming you're serious, the PC will only work with fuel injected bikes.
Question answered, thanks.

For all you other dick heads, If I knew anything about the shit I would not have asked, sperm breath. :banana

PS: look at my bike and see what a 92 zx-11 looks like, dorkos. :pisson

dude wtf are you talking about?

you didn't even ask any question.

hahahaha, speaking of sperm breath, your mom definitely should have swallowed.

What was the highest grade you attended?
A question starts with "What".
You are the only dick breath that did not understand the question, now go back to third grade.
Furthermore fuck face, leave my Mom out of your silly post, grow up.

Listen, I'll leave your mom out of it, but there's no denying that you should have been a stain on the bathroom partition in a crappy bar somewhere in alabama.

You asked what a power commander was. Then, immediately answered some question that had no bearing on a power commander, but rather had to do with ram-air on a CARBed bike.

If you read carefully, you see that NOBODY but you has any idea what's going on here. I mean you don't even need to read carefully, it's just apparent in every post.

Now, you explain to me how anything besides your question was even remotely related to a power commander, and then when you rack your brain trying to figure out what the fuck you were thinking coming down off your alcohol induced copy-paste session, you can shut right the fuck up. Thanks for playing.

:urowned by your own stupidity! Congrats!

What does knowing what your bike looks like have to do with anything?

Hang on, let me look in my mirrors, Oh yeah now I see your ZX11..
I am man enough to admit when I've been beat, as we all know it's not the bike it's the man riding that bike. Don't sing your praises to yourself until you have met me on the road.

As for Miss burnyourheartdown, grow up little girl.
26 years of riding various bikes has taught me to appreciate things new and old.
I don't act as though I know everything about everything, at 45 I still have a lot to learn, but I admit it is the difference.

This all started out as a simple question of what does a power commander do, and a select few of you turned it into a lets beat on this guy.

RayOSV is the only one who gave me an inteligent answer.

And I realized that I only answered part of the question. The purpose of a PC is to map the FI on a bike with greater resolution than the stock controller. The end result is better throttle control through the rpm range (less/no surging etc.) under a wider variation in environmental conditions (temp, humidity, altitude, etc.). Custom maps also allow precise air/fuel control with different types of exhaust and air filter systems which tend to make a bike run leaner than stock.

I think some of you guys are having winter widthdrawl problems or something. Lighten up. :)

You the man. Just how I like, to the point and all bases covered.

Thanks Bro,

Better resolution, really? I would think that with such piggybacks, as opposed to stand alone, you're limited to the dimensions of the stock maps.

I'd be interested to hear what someone who really knows a lot about the PC would say about this. I really don't think the PC is capable of redefining the addresses and dimensions of the maps, just able to edit the values within and calculate checksum. In automotive OEM fuel injection systems, it's more than difficult (and probably can't be done without manufacurer Damos (definition) files) to make the ECU access areas that it usually doesn't (and who knows if there will be room within the file to augment).

By "greater resolution" do you mean a more customized tune done cell-by-cell or are you actually referring to increasing the dimensions, and so total number of cells, in the maps?

I think maybe is was this post that got you off on the wrong side bud. Starting off calling people dickheads and spermbreath. Then you wonder why people get an attitude. For someone in their 40's you act like a teenager calling names...

The former, of course. Plus, as I understand it (not an expert at all), some older ECU's can't themselves be re-mapped while some of the newer ones can (?).
