    ...So if I already have FMF's on my Baja (flashed at the Dealer accordingly) and I want to run the CPR air filter, what is the protocol?

    Thanks!

    Here's the link to their site and off to the right is the Maps. http://www.rottweilerperformance.com/Downloads.html

    You'll either need Tune ECU http://www.tuneecu.com or a Power commnder V but if you don't already have the PCV go with the tune ecu which is free software and then build or buy a cable and load the map. It's very simple to do, it'll save your previous map so you don't lose it just make sure you hook up either a charged extra battery or a trickle battery charger so there's no hick-ups during the Re-map.

    Hello All,
    Thanks for your inputs, it was very useful.

    I saw a lot of votes for the "CPR" system.
    In addition I might need to change the mapping.
    Currently I have the Akrapovič mapping, should it be changed after installing the "CPR" air filter system?

    Cheers!

    Aaron, can you tell us what model you have? We have been dedicated to procuring FI maps for different model KTM Twins through our own dyno sessions, using Auto Tune for PCV and loyal customers as well that have had reputable tuners build maps and may have something that will work for you. Check here: http://www.rottweilerperformance.com/Downloads.html

    If you are using TUNE ECU, we have some files for them as well as this link here: http://www.tomhamburg.net/KTM_Tune_list.html

    Both KTM Twins and CJ Designs carry the easy to use Tune ECU cable and the software can be found here for free or with a donation to say thanks for such a great program: http://www.tuneecu.com/

    If you tune for an exhaust only -or- a Rottweiler Intake only, you don't "double" the percentage values with both. You will be safe with the AKRO tune for intake only and a little lean with the AKRO Tune for both exhaust and Rott intake. We do know that many of our customers do this with great success but nothing is as good (or as crisp) as a dedicated tune or the use of Dyno Jet's Auto Tune. Still, you can get away with building up one step at a time.

    You will find that our support runs deep as we originated the system (not a cheesy garage copy) and have some good in depth support and knowledge on the product so feel free to call us anytime you like and ask away. We have over 1K systems in use without one return, ever, so be assured that our system is a quality product.

    Cheers,
    CPR Fab / Rottweiler Performance

    BMC oiled cotton (like K&N) with a UNI pre-filter. The UNI catches so much dust that I wash and re-oil the BMC just once per year. Regular K&N filter oil on the BMC. No Toil on the UNI. Depends on the riding as to how often I clean the UNI. Perhaps every 1,000 miles of dusty riding. I ride a lot on the NW high deserts, and it's dry.

    I also installed the Head2Wind jetting upgrade, 4,000' setup.

    of the legitimate brands, there is no question that the rotti box by cpr is the way to go. they designed the system, have phenomenal customer service and put the time in to support the product with their informative website. (if you browse it) it filters and breathes better than any other brand and will actually yield real hp. the drop ins dont do squat imho. after carful investigation i bought one and have been grinning ever since.:lol3:lol3:lol3

    +1 for the cpr rottweiler box...

    Pretty much sums it up, did pipe, cpr, sas, cannister and had it dyno tune, what a difference, not only in power but in smoothness and delivery. Not to mention the room and ease of access. Thinking another storage box would sit nicely right behind it.

    +2. I've had 7 different airbox/filter set-ups so far. Sticking with the CPR. You have to stay away from the aluminum base plate.. Too much heat soak with it.
    This with a DNA will get you 3ft lbs, 3hp+- at REAL WORLD INTAKE AIR TEMPS.

    These set-ups were a fail. It took the raised roof c/f top and tall K&N filter to get even with the modified stock box.

    The one sitting across the subframe is the original Mars box that Motohooligan improved on. Again we are talking real world riding after hours on the trail. Not throwing on something and going for a spin around the block before everything gets hot.

    We have one. It will be ready for the KTM rally in September. Look for us there with the tool box and a few other goodies we are trying to keep quiet!! :evil

    ITG with aluminum plate all the way as it costs half the CPR alternative.
    Heat soaking of the aluminum plate is very easily rectified by using insulation material underneath it.

    While this all sounds good in garage theory, it actually only prolongs the agony, I.E., ramping time it takes to heat soak. One of the advantages of actually creating the system, is actually doing the research. Reading another thread on aluminum base plates will reveal statements like this:

    (On aluminum base plates:) "The only thing I noticed was it did seem a bit off on power after it was very warm." - "After riding a lot and pretty warm out, it didn't seem to have the same snap. No bogging, just didn't have the same power to loft the front wheel."

    When we originally started the R&D on this system, we almost trash canned the idea completely because of aluminum bases, but we didn't know that was the culprit. We thought the engines has an adverse reaction to breathing well or something. This has been seen on some Ducati and BMW models. Our first test units used aluminum base plates because they were more economical to make and looked pretty but we soon learned that every pull we did on the dyno lost more and more power and by the end of the session we were nowhere and nearly quit. One last ditch attempt using a polimer plastic hybrid blend of base material and hallelujah, there it is! Big HP found and armed with temperature probes we found that intake temps with our new base plate material never got over 122 deg F, even on a hot day. This is why most modern intakes are plastic. Pasting reflective tape will only slow down the heat soaking by a few minutes. (But sounds good on paper) Not to mention the damage that an aluminum baseplate will do to the throttle bodies from engine vibration. There is no way to isolate this damage other than make the costly investment to do it right with injection molding. Enter Rottweiler.

    The current crop of low budge garage copies unfortunately have not done their homework and making something that looks the same, isn't the same. There is alot more that goes into this product that you would think and it has been proven with our strong commitment to our loyal customers. Of which, we have never seen one return with over 1000 units in service. We roll most of our profit back into current and new products (Look for us and those at the Colorado KTM Rally!) and buying low budge knock offs will get you exactly that, a low budge knock off.

    I run the Uni oiled foam panel filter:

    [​IMG]

    No need to remove the airbox. No need to remove the SAS system. No need to remap the FI system. Just install and go. All the benefits of oiled foam without the hassle of the Rottweiler.

    It comes down to this:

    If performance gains are your thing then the Rottweiler will give you a couple of HP but will require a lot of work to get it up and running.

    If performance gains are not your thing and you want an oiled foam air filter that installs like the stock filter then the Uni is for you.

    For me the 113 ponies my 990 R puts out are more than enough! I just wanted a cleanable/reusable oiled foam filter.

    Cheers.:freaky

    Nearly 10 horsepower to be precise. (about 10%) But yes, you do need to remap as it will flow much more. To most KTM owners that is an easy price to pay for the gains. (There are many cheap/ free and easy alternatives to remap) Removal of the stock airbox is only done once and takes about 3 hours, (not very difficult) and dumps 3.6 LBS off the bike. 6 LBS in total with the SAS canisterectomy. Drop ins only replace paper with foam and are only about 1 1/2 hours difference in install time.

    In the long run over the life of the bike, filter access time is actually shorter as there is no longer a lid and snorkel to remove (10 or so bolts) and the filter comes off by hand to clean. Add a pre filter and cleaning / access are much easier than stock once in place.

    10% is a decent gain.

    This is a really good point.

    I'm just a bit too lazy for it. Also, I feel like I'd be getting in a bit too far over my head with removing the airbox and SAS, and remapping the FI system. If I could come to your joint and be walked through it that might help. Just not sure I'd tackle it on my own.

    Your 113 HP is on paper too--not at the rear wheel and not even at the crank. I haven't seen a 990 of any type that the carbed 950 won't run as good or better than. I have always found your numerous posts on how the CPR is a hassle to sort of ironic. It is one of the simplest modifications I have done to date--a couple of hours in the garage. With the foam CPR pullover filter in addition to the main filter there is not a better system for riding in extreme dust.
