Power Commander V ?'s

[HondaJon_imp]

I'm gonna try the PCV as it is out of the box with just the Staintune first and see how see does. If I am happy, I'll leave her alone, if not, I'll install the K&N, pay the $200 and get the custom map done.

I will also post it for everyone here to use.

And Ack, I did e-mail Dynojet, We'll see how they respond.

I put on the Staintune and was very happy with the sound. Have had 2 PCV's before on other bikes and wanted to run on the CB and felt it probably would improve when using the Staintune. So I installed the PCV, unplugged the O2 and replaced with the supplied "optimizer", blocked the pair hose, and ran the stock muffler with the PCV and the supplied "stock" map. I thought it was improved over stock. Then I installed the Staintune again and started looking for a custom map source.

Talked to Power Commander and visited a fairly nearby Dyno Tune source with some questions. Asked about the Air/Fuel ratio hose not being able to get past he cat. Dynojet suggested I run the Autotune module. I had the autotune on another bike and it worked well. Only thing, the O2 bung on the stock headers is 12mm thread and you need 18mm for the wide band O2 that works with the Autotune. To me, too much trouble to try to get some guy to install a 18mm bung in the stock header and expecting it to fit in the small space where the stock O2 is now. The DJ guy said they sell their kit to the dealers called the Stealth Extractor which they drill a hole ahead of the cat, install a rivnut and close off after the tune with a screw, to get to the exhaust on the upstream side of the cat. Sounds plausible.

Now I ask the tuning guy what about the cat? He says they do all kinds of bikes all the time and just shove the tube in and don't worry about it because the cat doesn't change the afr reading that much. I don't see how that's true because cars have a O2 sensor on both sides of the cat. So I don't want to pay for a Dynotune if I don't think its accurate because they sniff the exhaust downstream from the cat in the stock header. When I mention the stealth extractor, they don't know what im talking about. He says they can just dyno the bike then and see if there are any map areas that are way off for the afr and just change map area values by hand if the stock map needs it..... not a real dynotune or custom map.

So here I am. Can't go to Vegas for the hq guys to do it and I don't really trust the local dynotune shop to do a proper job. Might just have them dyno to see if anything is way off, make small adjustments, and run it as is until Power Commander comes up someday with the appropriate map for my setup.... or any setup other than the stock one.

Deanohh,

Thanks for your insight on this, I hadn't thought about how the CAT would affect the exhaust reading.

The stock map is sounding better and better.. I'm surprised DJ doesn't offer the autotune in different thread sizes..It seems like the way to go.

I'm just looking to dump that low RPM stumble, if I wanted another rocket, I would have a ZX-14.

I've read too much about k&n air filters letting too much dirt pass through. I don't trust them and use stock for everything. Some guys like em, just not for me.

I have never heard that one. I have been using K&N air filters for YEARS with no ill effects. I have never seen dirt getting passed them either. Besides....the filter media in K&N filters is finer than the stock paper elements anyway so the physics makes no sense for them to allow more dirt than a stock paper element.
To each his own. (don't want to start an oil type war).

I just added a K&N. The fit was a nice and snug like the OE. It does take the throttle a bit better. Which I expected since the stock exhaust is gone. I like it - K&N #HA-1301

I installed the Power commander V yesterday and the low speed stumble is now gone. Bike seems to run cooler as well. The unit obviously takes care of the EPA mandated “lean” condition. I think it was a well spent $269.


I am going to stay with the map that came with the unit. I'm only running the Staintune slip on and most likely won't do any other mods unless Pipemasters would like to donate me a set of their 4 into 4 pipes . I may try the K&N, but don't think it will make any noticeable difference given the vault-like design of the airbox.

It took me about an hour to do. The YouTube video Dynojet posted is quite helpful, but little things like figuring out the fuel line disconnect and how to run the two power commander plugs behind the frame (it is super tight) added some time.

Honda did an amazing job of hiding all of the electronic bits underneath the tank, but accessing the two center plugs is gonna be fun.

The K&N filter does help. I see PC has a stock map download on their website now. It must be different then the map we have? I'm not sure what's in our unmapped stock Commanders?

[Deanohh_imp]

The map that came pre loaded on my PCV is the same one that is on their site for download....... stock exhaust system, stock air filter....M16-040-01

[Ack-CB11_imp]

Thanks, I'll load that one up and see if things pick up. I'm hoping it's not to long before a few more show up on the website.

the map that is on the pcv will show up on the program when you plug your computer in or click get map. The map number will be at the top left side. Click on fuel to see the fuel table values. Open map and save map interact with your computer.... Get map and send map interact with the PCV.

if the downloaded map is for some reason different from the map on there now, the save map will put a copy on the computer if you want to keep the original. Then with open map you can put the downloaded map into the program. Then send map will put the downloaded map on the PCV.
