Power Commander

I am almost sold on getting a power commander for my 04 Just from reading here it sounds like a mod with a great return on investment. With that in mind, where is the best place to get one?

I have no plans on getting new pipes, but like what folks are doing with the 1" cutout. What opinions are there about a PCIII with stock pipes?

Thanks folks

I bought mine on ebay from Parts411 a few weeks ago to the door for $268.00.

I have a Leo Vince pipe, and love the improvement after the Power Commander.

Can't speak to other mods...

Get one, and enjoy!!! :biggrin:

Check Indysuperbikes.com. Pretty good pricing there.

I noticed by looking at the Power Commander website today that the new model (PC V) has an AutoTune accessory, which basically turns it into a closed-loop ECU.

About time! Stock car ECUs have been doing closed loop for over 10 years.

Of course, the PC V isn't supported on the VFR. :angry:

Yes it is, you just need to remap it.

PLUS. Without the Autotune, the PCV works just like a PCIII (albeit with one additional throttle percentage) for basically the same price, and let's you later go to Autotune if you'd like.

Unless you can find a PCIII for much cheaper, I'd go with the PCV, basically the same, but you can later upgrade it if you want to!

No suggestion for the "best place to get one." But, It smooths out all that throttle response crap you used to just put up with between certain RPM's. Kind of a driveability solver! You will like the linear power delivery without flat spots all the way through VTEC kick in to redline. You know, the way the factory shoulda' set it up in the first place! Do download and try Cozyes map, though. You'll like it. Enjoy!

PCV also includes O2 elims, so the end price is less than the PCIII.

Good price--- More Power Racing $282 shipped.

My '04 was OK before installing my PCIII and O2 sensor eliminators (which I bought during a VFRD group buy a couple years ago). Before I installed the PCIII, I had 20k+ on the odometer, the VTEC transition wasn't bad but it was noticeable, and had some surging in lower gears at 5-6k rpm.

The PCIII smoothed it out nicely. The surging is gone and sometimes the only sign I've hit VTEC mode is the increased sound from the engine. I highly recommend it. :fing02:

If you're going to mod the OEM exhausts, most people start with gutting the cans. Should give you an increase in volume without investing big money or doing a lot of cutting, etc. With the stock cans, go with (VFRD member) Cozye's PCIII map. There might be a different map for gutted cans, but I don't know for sure (since mine are stock).

I don't claim to know much about this stuff, but I just installed the PC3 on my '04 with Cozys's map uploaded to it and for me it was truly a night and day difference. Picked mine up at Motorcycle Superstore $279 shipped. I had a fairly sever throttle chop and the 4.5-5k stumble. I went the .99 cent Radio Shack resistor route which was simple to install. The whole install was a cake walk actually. Trust me if I can do it, any one can ;p

My highly anticipated PC III showed up yesterday, I installed Cozye�s map and I need to say it has made a significant difference in the ride ability of my 02. Prior to the installed my bike suffered from that annoying flat spot in the magic 3500 to 5000 rpm range. While I loved the VTEC kick it was a little unsettling at times and riding the bike in the VTEC band is going to get you a ton of police like trouble. So now my bike is serviceable and will give me all that I need for the average joe commute, fun on the back road twisties and great roll on performance when I need it. The most noticeable and welcomed change is low speed riding and the way the Cozye�s map handles the on off throttle.

I did by pass the O2 sensors using the radio shack 330 resistors, but getting those dam connectors to separate was the toughest part of the entire install. I have yet to compare the mileage and document the difference between pre and post op.

The only thing that I have to do is learn how to configure my own map. While I see the ranges in the map, I don�t understand how we would arrive at one variable over the other.

If there is anyone out there that has a simple method to analyze or build a map, or at least a simple explanation of what the individual numeric ranges mean, I would be interested to hear you ideas.

Long way to say, this is by far the best $300 I have ever spent.

I have the PCIII now. Onboard and loaded wuth a good map. I found a deal through Cycle Gear, they matched an internet price. It is on and I like the results. I also opened up the pipes a little. The Craftsman drill bit solution is what I went with. Easy, quick, and a good first step. After that, I felt it necessary to do something about that clown car horn the bike came with. NAPA has replacement horns up around 132 db for under $20. Now the bike has balls and horns.

do you have the napa part number for the horn?

I am curious about the new power commander V with auto tune. I have an 04 with with a pc non usb and o2 eliminators, catless pipes, bmc and so on. I am running Tinys map and it runs really good but may be a bit rich. The auto tune feature seems pretty cool to get the bike running just right. Anyone have an experience with this?

They had about 10 hanging on the shelf and I just picked one with the single bolt on th eback, they all looked like they had it too. I just picked one and it worked. You might want to pull yours off (10mm) and compare. All in all, nice to be heard. Give it a go.

You list your location as northwest. The wife and kid are visiting her mom in Cali for a 3 weeks and I'm always looking for an excuse for a road trip. If you'd like to meet up somewhere and check it out, I'm up for it. Just PM me.

Just so you know, a member currently has a PCIII usb for sale for under $200......

A PCV will work on a 02-08 VFR? Why does it say 2009+ only on the DynoJet site?


I'd love a PCV just to switch between two maps on the fly. Coyze's map doesn't work at high altitude for me, the bike almost doesn't idle at all when I get up on some of the Sierra mountain passes (>8000ft).

Because the map is for 2009+, I think. I know for a fact that any PCIII with the correct Honda connectors will work on any VFR if you load the correct map.

Check out Coderighter's thread, it has all the info on that you need!

Gotcha... so the only reason to "upgrade" from PCIII to PCV would be for autotune, since right now there ARE no maps for the pre 2009 bikes. Looks like I'd have to make a map to assist with the VTEC transition. Still, it's tempting... I'd like someone to compare PCIII+Coyze to Autotune.

Actually, the PCIII maps will work on any PCV. The only difference there is the addition of the 15% throttle position. So you could take a PCIII map, such as Cozye's, add that one throttle position (you can just split the difference between 10 and 20) upload it to your PCV and you're all set.

So the reasons to go with PCV are: it's basically the same price, one more throttle position, generally comes with 02 eliminators, and the ability to upgrade to autotune at a later time if you want.

Ok, the fact that Dynojet doesn't have PCV map for anything other than a '09 makes no difference.

All you have to do is open a stock '09 map with the PCV software, re-size to half screen. Then open PCIII software with whatever map you like, lets say Coyze's, make it the other half of the screen. Now simply copy and paste the rows vertically by throttle position skipping the 15% row. Currently, the PCIII averages between throttle positions at a given RPM. If at 4000 RPM you have +4 in your 10% throttle and +8 in your 20% throttle its going to give you +6 at 15% throttle. So using this info, you can now go through the 15% throttle row and fill it in with the average between 10% and 20%.

At this point, you will have the exact copy of the desired PCIII map! Once downloaded to the PCV, it will perform the exact same!

ANY PCIII MAP CAN BE A PCV MAP!!!!!!

By the way, you will find that you can lean out the 15% alittle because it's more in the "cruise" area. You can also make the 20% a little richer for better throttle response because it's pretty much out of the cruise area. This is the reason they added the 15% position, to better define the "cruise" area.


I have posted images of the PCV stock '09 map and the PCIII stock map for '06-'08. They are the same except for the 15% row. This tells us two things-

1. '06-'09 VFR have the same mapping.
2. The PCV and the PCIII "operate" to change the mixture in the exact same way.


The PCV gives you all PCIII features plus-

1. Autotune option.
2. Mapping by gear, which is needed to do a proper map on '06-'09 because they have factory "map-by-gear". On any model, you don't have to run cruise settings in 1st, 2nd and/or 3rd making those gears much smoother.
3. Enrichment by temp, could use this on warm-up or add more fuel when running hot to help cool things down.
4. Operate Dynojet Quick shifter
5. For those of you thinking blower, there's a input for a pressure switch (0-5 volts) so that you can add fuel based on boost pressure.
6. You can load 2 maps (if not using Autotune) that can be toggled on-the-fly.


Note:

Their 15% in the table below is not an average of 10% and 20%. They dyno'd for their numbers. The average method I stated above will just give you a PCV "copy" of your PCIII map.

I'm not looking for a reason to get the PCV instead of the PCIII... I already have the PCIII. I'm looking for a reason to upgrade :).


I'll probably wait to hear from someone on a 02-05 who switched from PCIII+Coyze to PCV+Autotune.
