  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

449 / 511 recap and info

Another question, if I buy the programmer V and FMF pipe then will I still need to take it up to the dealership to remap it? Or will the programmer adjust it based on the maps provided with the purchase? I think the programmer will do the trick, but I don't know?

If you get just the PCV it comes loaded with a map for stock. If you want a map for a open exhaust it can be downloaded and loaded into the PCV via USB and a laptop. You can also go in and modify the table yourself but this is guess work unless you spend some Dyno time doing it. If you get the Autotune add on to the PCV it included a wide range O2 sensor so it is actually reading your exhaust gas and working constantly to keep the mixture perfect. The PCV is manual and the autotune add on makes it automatic like you described.
 
Cheapest and stills runs like a scalded dog. Power up plug, FMF quietcore 4, and open exhaust map....
No stalling, no popping on decel, smooth throttle response, all the wheelies you want with just the throttle,
No cluch popping.
I never heard back from you about adding BMW map#3 in my upgrade thread. So that map did work out for you??

The Autotune costs about the same as dyno services and is what I recommend you purchase with the PCV. A less expensive option is to get a remap done on your stock ecu with map set #3.
 
Maybe it is already installed as the thing is almost unrideable without it IMHO. Scary lean and likes to stall / toss you over the bars.

Factory power plug - runs OK
Factory power plug and decatted muffler - better
power plug and real muffler - good
Send your ECU to ZipTy to remap - very good
JD and muffler - now were making some power
PC5 and muffler - Tons of options, maps and big power

Oops forgot about that most excellent option so I added it to the list. :thumbsup:
 
they should have given it to you. I will try to dig up a pic but it is a little loop of wire (might be all it is so you could make one) that plugs in right under the seat.
No jumper installed, jumper sitting loose on ECU:

All I did to protect the O2 sensor harness connector was to fill it full of dielectric grease, then use a piece of adhesive lined shrink tubing over it and then crimped the open end of the shrink tube with a set of needle nose pliers to seal it when the tubing was still hot. Above the head on the right hand side are two electrical connectors / relays mounted so I removed the zip tie holding them together and sandwiched the O2 sensor harness connector in between them and then also zip tied the wiring for the temperature sensor in the rad that in now hanging loose to the 7602 rad braces I installed:

Why did you remove the O2 sensor? Not necessary to do so but will runt he same ether way.

The plug came with it, it is one less thing to rip wires off when going through tight bush, it took 5 minutes or less to do and if the O2 sensor is not being used why bother having the O2 sensor heater powered?
 
I have ridden the 511 enough now with this installed to think I don't need the PCV etc....very pleased,
Smoother lowend, just richer all over, better throttle response, I think I will ride it like this for sometime,
and skip the TC airbox etc....really think this is the ticket, I know there is more power to be had, but it's
Really nice now, I am of course talking about the open exhaust map
 
Well fellows, I just ordered the programmer V, FMF Q4, and an ignition switch (to keep my loser friends from taking my new toy for joy rides when I take a pee break). Should all be delivered to my house soon. Then I will be back on here reporting the results. I will download the open exhaust map from the DynoJet Powercommander website and install it onto the programmer and then remove the stock muffler and install the FMF Q4 exhaust. Depending on the results I may opt for the "autotune" component; but I suspect the open exhaust map will suffice. Before I start tinkering with it; any advice would be greatly appreciated.
 
When you get the pcv installed, you may have to download and install the stock air box map. After that, your options are a 250 dollar dyno visit or an autotune.
 
That's not too terribly encouraging. I thought the PCV would suffice with the FMF exhaust. Are you sure it will not work with the PCV and FMF exhaust? PCV website allows me to download all the maps onto the unit; and then could I select whatever map I chose without getting it "dyno'ed" or using the autotune. I plan on leaving it set in one setting once its mapped. Sorry for the stupid questions; it am making assumptions based on the Yamaha WR250x which I added an FMF exhaust and programmer with a particular map and it ran great afterwards. It too could have used the autotune but never needed it.
 
The powercommander 5 and autotune are the best options. But you will have to try it without and see how it works for you.
 
It won't mess anything up if I run it without the autotune to see if I can live with the changes? Also, I read another thread on here regarding the longevity of this brand of bike and the expected life span "averages 14,000 miles" is this correct? Man, that is not a comforting thought; because I come from a history of putting that many miles on my bikes in a years time. A bit worried ....
 
You will be fine with the PCV alone. Very good maps and several map options. Heck you would probably be fine with the remap on the stock ECU ZipTy does.

Thats a lot of miles to put on a off-road oriented dualsport bike. Not sure my butt would survive :eek: Most motorcycles short of touring rigs tend to take several years to run up 14000 miles.
 
These are race bikes that are street legal. I have "other bikes" for pounding miles...DRZ's KLR's Terra, lots of others,
Are good for that purpose, enjoy the TE for connecting the trails, and play riding. If you use it as a commuter, etc...
It probably won't last the mile of some of the "other" bikes...I tend to ride 12000 to 15000 a year also, just not all
On my dirtbikes."
 
Yeah I am a bit of a rider :-) ... It's not much for me to put 200 miles of dirt riding in a day ... I like to ride; it's about exploring and enjoying the good single track where no one has been in years :-) ... Most of the time it's around 100 miles per day
 
And the iron butt award goes to....

With that kind of mileage, perhaps you should look into Seat Concepts. You can turn that slightly padded 2x4 into a nice cushy thing that won't make your cheeks look like a baboon.

All the horsepower in the world won't make your butt feel better.
 
Lmao! Yeah I do suffer from baboon rear from time to time. But the seat is about the same as the wr250x I have so it's not too bad comparatively. I am more concerned about the lack of dependability. But I am not going to change my riding practices; if I have to rebuild her every year then so be it :-). I love the way she rides and looks.
 
Unless you're pretty handy wrenching on bikes my advice would be to find a mechanic who's got experience with FI and Power Commanders and
have him install it and dial it in. If you can afford both the PCV and Autotune that would probably be awesome but a good mechanic can get it
dialed in with the software without having to spend the money for Autotune.
The Dynojet website has a list of certified shops that they're affiliated with but really you just need to find someone who knows FI or attempt it yourself.
A lot of trial and error and guess work if you go that route,though. Once dialed in, though, it's the shit. Good shit. :thumbsup:
