    Has anyone purchased or had experience with an item from Wunderlich called a "performance controller". I have seen it listed on BMW Santa Cruz web site and am curious about it. Thanks.

    Wait for the power commander to come out . It's gonna be better. It will let you tune the mixture more precisely. I think the one your talking about is made by techlusion wich only lets you adjust low mid and high. And you can't lean the mix . Only richen it. Which is most likely what yiour gonna want to do anyway. The power commander lets you adjust the mix in like 100 points through the rpm scale. I've been waiting for it to come out for like a year and a half. Bastids!........Oh ,I'm presuming you want it for the 1200. They have them for the 1150 already

    Gray Ghost,

    My 1200 was the test bike for the original Techlusion "controller". Dobeck Performance in Belgrade, Montana is the original designer and the manufacturer.

    I CAN attest that my 05 is more powerful as well as smoother than it was pre-controller. I did also add a full Remus exhaust at the same time. I'm happy with mine and have had zero problems. BUT....It was installed and set up by experts.

    Do a search....... as this subject has been covered before.

    I just installed a full Remus system and gotta say "wow"! Don't think I need a controller, but there is a little back pressure. Could that be from a lean mixture or an air leak? On full throttle the system is smooth as silk with more power. How could anyone want more?

    I have the Techlusion performance controller on my '04 R1200GS and the difference is noticeable, particularly in hot weather.
    I believe that the Power Commander will be a better unit, as for previous models, but it somewhere around 400% more expensive: you get what you pay for.
    BMW Boxers typically run lean to meet European emission standards, so richening the mixture can improve a number of areas, except of course, fuel economy.
    In addition to improved low end pickup, better mid range, and smoother running, I also noticed smoother gear changes while commuting. I think what happens is that on standard mixture settings, i.e. lean, the engine tends to die rapidly off-throttle and then the transition on-throttle is soemwhat abrupt. A richer mixture smooths out the transitions, and thus the gear changes, but I'm only theorising. But I have found gear changes much better in stop-start traffic.
    As for fuel economy, after much fiddling with the unit, seat of the pants stuff only, no dyno, I my current settings have reduced the normal touring economy from 20.5 km/litre to 18.7 km/litre, a reduction of around 9%.
    Is it worth it?
    Not sure.
    I suspect that if I was doing a lot of city work, then I would say "yes".
    But for mainly country touring, which is what I do, I don't think the performance improvement, at an acceptable fuel economy reduction, is worth it for me.
    I tried some richer settings which gave greater performance gains, but with a 25 - 30% increased fuel usage, which is what you would expect.
    Anyone want to buy a used Techlusion for their R1200GS?

    PM Daotoys. Also do a search in Gspot, there's a good thread on it.

    As has been said there is a great thread on this subject on the site, this http://www.advrider.com/forums/showthread.php?t=108845&highlight=techlusion should take you straight to it.

    As far as Power Commander goes I've used their products on previous bikes but any question about availabilty for the 1200GS got the response that currently they have no intention of producing one but kepp in contact as that might change in the future, as yet it has not.

    Wunderlich as a company rebrand other products for sale, the power controller as has been mentioned is made by Techlusion so whether you souce one direct from the manufacturer or Wunderlich comes down to location and cost, being in Europe I went for the Wunderlich version.

    I have a set of Remus headers with a BMW Akra can and a green airfilter (its exactly the same as Wunderlichs blue filter just sourced direct from the manufacturer as it was 33% cheaper) and the addition of the contoller in my opinion is worthwhile as the bike runs smoother and there is a noticeable increase in power and torque.

    While it does not have the range of adjustment a Power Commander offers it's available now and does not require connecting to a computer to alter the settings.

    I'm not sure it's a must have modification but if your changing exhausts and filters it's one I would definetly consider.

    <BR>Has anyone here done their own installation of either the Wunderlich or Techlusion on their 1200?

    If so could you answer a question or two?

    Does the product connect to both injectors AND both O2 sensors?

    Thanks.

    Yes, it does. Installation is all plug and play. Takes about 30 minutes. Less than half that to remove it.

    Since we're on this topic, and if someone was comparing this product with the one from Rhinewest, are they basically the same? Or is thiere a significant difference between the two?

    TIA

    completely based on what I recall (highly suspect, so you should search the topic), the Rhinewest chip produces a richer mixture across the board, whereas the Techlusion is adjustable in various ranges.

    I don't think I've seen a dyno comparison.

    On the site I noticed it says, "Intended for OFF ROAD use only!" Hmmm...is this because of EPA restictions for on road use in the US?

    likely that it is illegal to mfg such a product. I asked the company that makes the techlusion if it was illegal and they said "probably, but you're a weenie for asking" :wink:

    Strictly speaking the controller will change the emmission levels making it unsuitable for " road use" not only in the US but Europe as well hence the disclaimer.

    Hmmm... I am tempted. PM me with price if you are serious. I need to get some k's on my new GSA so I could pick it up (I'm in Sydney)

    For what it's worth... I have an '06 R1200GS that I started with stock and then added a full Remus system keeping the stock air filter and the DB Killers (canister restricters) in place. There was a marked improvement in power especially at the top end but the bike definitely ran leaner as a result...

    I then added the Techlusion controler with the recommended settings for the stock bike--fantastic! The bike runs smoother throughout the entire RPM range eliminating the lean condition and mild backfiring on deceleration. It's not so much something to increase power as it is to improve smoothness, engine response and drivability by reducing the inherently lean condition that was even more amplified by the aftermarket exhaust. It's now creamy smooth like what I think the bike was meant to be. Gas mileage did drop a bit from around 44mpg to 40mpg but for me it's a small price to pay for what now feels like an engine that's finely tuned to perfection. I think it was a bargain for the improvement it provided :)
