Looking for advice regarding Power Commander

Looking for some advice regarding a power commander.

I just found a great deal on a brand new power commander 3 for my 03 zx6r. $225 total shipped.
My bike has 31,700km on it, or about 19,000 miles. I have a Danmoto Carbon GP slip on exhaust and a K&N air filter.
I live in Nova Scotia, Canada and haven't found anywhere near me yet that has a dyno and could make a custom map.
I looked on the Dynojet map database and could not find a map for my bike with my exhaust and air filter.

So basically, is it worth it for me to buy this power commander?
Will it still benefit me even though I don't have a custom tune?
Is there a base map that I could use with it that would cause an improvement in the bike compared to not using a power commander at all?

Any advice is appreciated. Also, if anyone has the same set up as me and already has a map for that set up could you please let me know? Thank you.

Read the following: The Breakdown on Fuel Management Systems

The Juxtaposition of Flashed ECUs and Fuel Controllers

Then decide.

Thanks jd41. I've read through both of those and I still don't have an answer. I was hoping for clearer advice I guess. Will it still benefit me even though I don't have a custom tune? Is there a base map that I could use with it that would cause an improvement in the bike compared to not using a power commander at all? Those are the two questions it boils down to, I was hoping for a yes or a no, or even if someone may have the same set up as me and could point me in the right direction for a map.

If anyone else has any advice I'd love to hear it. Thanks again.

I honestly would buy it if I was not going for a custom tune. .

Haha sorry I am more confused now, did you mean to say you "wouldn't" buy if I was not going for a custom tune?

I believe a power commander just modifies the fuel table. A custom tune would involve quite a bit more. Specifically the spark/ignition table.

I was considering picking one up as well and would like a lot more clarification on how the 03-04 EFI works in general. It was the first year on this model for EFI and works differently from more modern EFI systems in that it has no O2 sensors for any real feedback. From the service manual, I see that it has inlet air pressure and temperature sensors as well as an atmospheric pressure sensor. That tells me that the system should be able to use a base map and work out differences in temperature and pressure at various elevations, but some forum search results tell me that a map from user X in who knows where will not necessarily work for my bike at my elevation, etc. as if I were trying to get jetting recommendations for carbs. Isn't the Power Commander just modifying the base map while your ECU makes up for differences in atmospheric conditions?

I understand that no two engines are the exact same, but it seems as if you could at least try the various slipon fuel maps from the website until one felt right. This is of course useless if you need every last horse and are going to the track, but it goes without saying you should pay for the custom tune then.

Also, for novak, if you haven't already I would definitely recommend a valve adjustment (if it hasn't been done or if you don't know the history of the bike) and a throttle body sync before you throw any money at any sort of fuel mapping. This is on my list and is the real reason I haven't looked too seriously at a PC, yet.

If your getting one, look for the AutoTune and quick shifter.

Many don't have access to a tuner and if your bike is modded good chance it was never tweaked.
This should help with performance.

Thank you everyone for the replies.

I had a valve check done last season and everything was within spec. I had throttle body sync done as well and will probably do the same this spring as well.
I don't do track days, I strictly do street driving.
I figured a power commander would smooth out the throttle a bit.

I know I can frig around with some of the maps online and see if one works well with my bike, but what I'm wonder is does the power commander come with a base map installed that is any different from the stock map on the bike now?

Basically, without having access to a dyno, without having acesss to AutoTune or quickshifter, with just having the power commander with either a base dynojet map (not stock ecu map) or one of the downloadable maps (two brothers, akra, etc) is it worth is for me to buy this power commander? Will I see any improvement in throttle smoothness and idle?

Again, any other info is much appreciated! Thanks to everyone who has contributed!

IF You ever plan on getting it tuned, yes.

OR wait and pay full price when you get around to it.

Not planing on more mod's or tuning why bother. One more thing to break.

IMO, frigging with maps unless they are for a bike with your exact or very close setup is nut's.
Your playing roulette with A/F ratios since you don't have a good gas analyzer hooked up.
Could you get away with it, yes. Could you fry some exhaust valves being to lean, yes.

That was why I suggested getting the AutoTune.

Last word, either do it right or leave it alone. That's just me.

I was kinda worried that if anything the bike could be running a little lean now that I added the Danmoto exhaust and K&N air filter. I thought the power commander would help make it richer.

I emailed Dynojet and they recommended trying the #M207-002 map which is the two brothers slip on with stock or aftermarket air filter map on their database.

If that tune is for your bike, and other mod's are similar than go for it.

You could look at your plug's to see if there white, but getting to them is a bit of a challenge.

Autotune is only for PCV. I dont think PCIII has access to one. So you'll be on your own or dealing with a tuner. I doubt you'll burn a valve but you probably wont get the best map possible on your own. Even when you are doing some manual tuning.

225 seems high. I think you can get a used PC3 for less secondhand. I dont know if they made a PCV for the 03/04, you'd have to look.

Also careful with the danmoto exhaust. I'm getting rid of mine because its not meant for my year, but I've heard theyre risky.

The power commander is brand new in package, so for $225 total I think that's pretty good.

I was wondering what is so risky about the Danmoto exhaust? I ordered the correct exhaust for my bike and year. I haven't had any issues with it at all. The bike runs better with it on then is did when I had my Shortened Hindle exhaust. What's the concern?

I dont know much about new prices to be honest. I try not to buy new if I dont have too (like a helmet. I will always buy helmets new). Don't see why if the part is working and not going to be seen.

As far as Danmoto goes, they are just susceptible to the normal chinese manufacturing risks. Low quality and tolerances. In this case there have been reports of fires on bikes with these.
