Power Commander V - Advice

I order a Power Commander V  for my STOCK 04 VFR800 and wondering if you guys have any advice on maps, install location and such. Thanks :)

I recently downloaded the Cozye's Map Modified for an 06+ VTEC from the downloads section and I am in the "trial" stage. So far it appears to be working well. I have only gone through 1 tankful so I cannot comment on the milage, but it does look like I am getting a little less milage that with stock setup. That being said, I think it's a small sacrafice for the large improvement on the low end stutter. Check out the Downlods section on the forum and look at the Power Commander downloads, people will leave comments on how it worked out or didn't work out for them. I know as soon as I get a few more tankfuls run through, I'll be posting my comments.

Cheers

Cool. I was thinking the Modified Cozy djm map, but not 100%. I'm kinda worried it's gonna damage the engine or something.

That map is for PC3, how did you manage to get it to work with PC5?

I don't have the PC V yet, but I just installed the software and loaded the Modified Cozy djm map.pvm, so it should work. I'll know for sure when I get the PC V in a week or so. That file has the .pvm extension, so it must be for the PCV.

I stand corrected, I tried to use this map by using the "import" tool in the software. For some reason it wouldn't take, so I did end up using the Modified Cozy djm map.dvm. I had to break out my laptop to double check, my desktop shows that I downloaded the Cozye's Map Modified for an 06+ VTEC so that's the one I thought I had used. I'm not sure why the import process didn't work but from my understanding of the software, this is supposed to all you to "update" your older maps to the new format.

As far as damaging your bike, unless the map is so radically tweaked, the worst you should get is a too rich or too lean condition. Where the former would more likely foul your plugs, but the latter could cause more trouble. You should be able to tell right away if it works or not. Of course the best way to avoid any worries is to have it properly Dyno tuned or to use the Auto Tune device, both will cost you a bit more, and would require the disabling and/or removal of the PAIR valve system.

Cheers.

So I wonder what would be the best map for an 04 VFR800 with stock setup? I'm a spirited rider ;)

tried all european maps here in UK for my 07 vtec with staintunes.
Solution: Dyno set up by the amazing Paul of Dyno bike. All I can say now is WOW

I was thinking of doing the PAIR mod, but is it needed since I installed the O2 eliminators that came with the PCV?

Not to thread jack, but it's on the same topic and didn't want to start a whole new thread.

Just ordered my PCV for my '06. I'm running a LeoVince Carbon exhaust, K&N air filter and otherwise I'm stock. I'm looking to smooth things out a little and just tune it appropriately for my mods. I'm hoping to get the best mpg I can, at least while in higher gears. What maps should I be looking at? Oh, and if I don't install the O2 eliminators, I take it that could save me some fuel efficiency at the expense of still having some of that snappy throttle as I go from closed loop and back.

Looks like this is pretty much made for my setup (Dynojet for LeoVince): http://www.vfrdiscus...t-leovince-map/

And this looks about right for what I'm looking to get out of the bike (cozye's modded for '06): http://www.vfrdiscus...for-an-06-vtec/

Anything else out there? Maybe I sort of combine/average the two?

M8, I have to admit to still toying with idea of a PCV for my 08 but the cost, especially with a dyno run on top, seems to me to be prohibitive at around £500 for the 2. Is it really worth that much or did you get it all done for less? Thanks.

I just installed the Leo Vince Evo 2 cans. I love the look and sound, but it runs really poorly without the DB killers installed, which obviously defeats the purpose. So, I guess it's time for a PCV. I was looking at their website, but it's not clear to me if you can switch maps on the fly (it may be nice on longer rides to put the DB killers in - does anyone know if this is an option?

Also, what else is recommended to change besides an upgraded air filter? I don't want to mess with the PAIR valve or O2 sensors unless it's really necessary. In short, I'm not trying to go crazy here, just smooth it out and enjoy my new cans.

Thanks,
Jeff

PC 5? I have to ask , if the bike is stock, whats wrong with the stock map they provide for the stock bike, thats where Most their engineering effort is applied to. If they cant get that right, that doesnt say much for their product.

From the research that I did, in order to get the proper readings on the Dynometer you'll need to disable or remove the PAIR valve system. If you plan on just using an off the shelf map, or someone else map, then you should not need to worry about it. The O2 sensor eliminators are a must though. And yes, with the PCV you can toggle between two maps using a contact closure switch. However, if you use the Auto Tune module, then you'll lose the ability to run two maps, as the AT module takes the second map location. Here is a post I did showing how I put in a toggle switch that works with the PCV and did not require any drilling or a lot of money.

Perfect solution! Just need to get over paying for our summer vacation and I'll order up a Pcv. Until then, I'll just leave in the DB killers.

Agreed. I've been on the "hamster wheel of pain" regarding tuning since 2010. I purchased a PCV, Autotune, Motad headers, and had a custom tune done, all on the original 2002 ECU.
Since then I've dropped in a 2006 model ECU, kept all the mods (Staintunes, K&N, Motad headers) and completely removed the PCV and the Autotune. Bike runs f*cking fantastic.

The more research I do on EFI tuning, the more I believe that the Powercommander really can't fix what we want it to fix, and that's jerky throttle response. IMHO, it only "works" at large throttle positions where the ECU is in Alpha-N mode, because the Powercommander is also an Alpha-N (throttle position-RPM) device.

When you get down to small throttle positions on the bike, the ECU is a Speed-density system (Manifold pressure-RPM). After all this time, I have decided that overlaying an Alpha-N map adjustment over a Speed-Density controlled fuel mixture is a roll of the dice. It may work, but for which gear, and what altitude?

Ergo, I say only a full replacement ECU like a Motec using a wideband O2 sensor for true closed-loop mixture control will really provide a *proper* fix for low-speed jerky throttle response. However if yours has been tuned with a Powercommander and works well, keep it that way!

OK, you got me. Explain how dropping in an '06 ECU fixed all your issues with your '02 and the mods you have. I have an '03 and am doing very similar mods. Are you saying swapping to a later model ECU is the simple soulution, easy peasy? How does that work and do I just order the part from the Honda dealer? Anything else to know?

Anyone know how to get a PCV with autotune to work on a 5th gen? I've got a Y2k with '98 ceramic coated headers, about to install a Motad Scorpion canister, BMC air filter w/ Coderighter mod, Toro PAIR mod, O2 eliminators, de-flappered & de-snorkeled... I think that's it... for now...

...and completely removed the PCV and the Autotune...

So, like, Kaldek, is your PCV for sale to another member who might be interested in getting a good deal? :-)
