This Unit Delivers on it's Promise, But...
This unit does everything that it promises. The power delivery is smooth and robust, the popping and sputtering on deceleration has stopped (full Remus header/can), and while my mileage did take a hit, it wasn't has bad as expected ( I am still getting about 43 mpg if riding fairly conservatively).
Where this unit falls short of my expectations, is since installing the unit, my Mileage and Range tracking are now totally worthless. When planning rides and routes, particularly on the fly, I rely on these two features for tracking fuel, and route planning, as it pertains to fuel stops, etc. The Range and Mileage readings are now showing approximately 10 +/- greater fuel economy than I am actually getting. So, it will read 51 mpg, when I am actually getting 41 mpg. A 50 mile difference relatively negates using these features for route calculation/fuel consumption when things get tight.
I sent an email to Wunderlich USA regarding this issue, but did not hear back. I then contacted Dobeck Performance, the actual manufacturer of the unit. In a nutshell, they said the way the unit reads the oxygen sensors, and then recalculates the amount of fuel that is injected, makes this situation unavoidable. I was also advised that if I was on a lengthy ride where fuel calculations were needed or critical, I could disconnect the ground wire to the system and that it would disable the performance controller, allowing original fuel mapping pass-through.
Were it not for this particular issue, I would have given the unit a 5. At this point, I believe that the "ridability" gained, exceeds the mileage/range accuracy issues. But, I am calculating mileage manually now at fuel stops.
The bike runs great!
A real improvement in my 2004 R1200C Classic!
I knew when I bought this model that it wasn't a roadster/sport-touring bike (like my last BMW: an '04 R1150R) and I wasn't looking for that, but ergonomically, this is the model for me. Except that it wasn't very smooth in slow-going, parking-lot speeds and around-town performance.
The Performance Controller nearly eliminated the 'anemic' low-RPM throttle response ('flat spot') that I was experiencing. I took a few test rides after the install, with the BMW Tech making an adjustment after each one, and each time was better than the previous. After I feel it out for a while longer, I may 'fine-tune' some more adjustments/settings.
For now, there's practically no more slow-speed sputtering in stop-n-go traffic. I'm really very pleased with this mod.
Works as advertised
Installation was easy. The instructions were good, until it came time for programming.
A call to the manufacturer did the trick!!
The wiring harness is way too long. I guess my next project will be to trim the wiring between the control box and the "Y" junction.
The program seems to light up the performance and throttle response.
I have not had a chance to check mileage as of this writing. I hope the drop is not too significant.
I was initially a little intimidated by this products instructions, and the demo for adjusting. I installed the tuner with a friend on stand by but didn't need help, everything went great! Adjustment is a breeze, if you don't get it just the way you want it the first time it's very easy to go around again! With the Remus header and slip on, it makes a HUGE difference in the way this bike behaves! Well worth the money!
Works As Promised
My ride the 2007 R1200s , no cat,remus exhaust,zard silencer,
K&N filter. Installed easily,fits nicely under the seat. Used the
tuned setting for the R1200s and I\'m pleased with the result.
Throttle response crisp , no popping from being to lean. Gas
mileage drops a little but well worth it.
Installation Instructions Not Clear
The product is good. But I had trouble with the installation guide. It said to take out the ignition plug and put it on the plug on the PC. The removed plug, you plug it into the the PC also. Since I have a F650GS Twin, the instruction didn't say that I had to repeat this process for the other ignition.
Finally, it said the lambda sensor was right behind the rectifier. We looked and looked and couldn't find anything that matches the illustration J components. We found something close to the frame (towards the rear shock) and we were lucky that that was the lambda sensor alright.
Overall, the baseline numbers work great. Will be trying out different settings in the coming days.
This was very easy to install and to tune as per instructions. Recognizable response on all gears and power boost even without sport headers and exhaust. Will tweak further as I ride more. Overall a great product and simple to use even for the most basic bike enthusiast.
Easy to Install and good performance
Choroge The Rider
My BMW are K1300S,K1200R,R100RS,and F650GS Twin.
Original F650GS is poor power I feel than OHV-2V.
This controller is,
Very easy to set-up,Good acceleration,and more power.
Does the business
Very impressed. I installed on a 2007 R1200GS I just bought with about 14.5kkms on the clock. The bike has Remus headers and can and as a consequence was 'popping' on the overrun - which always concerned me (dont like bikes running lean). The ordering from the states was a breeze - even to Oz - and the installation a piece of cake. Took about 40 minutes with the hardest bit working out the neatest run for the cables rather than anything difficult. Immediately after install the popping is gone which is great. I'm now playing with the settings to see what differences the various mix ratings give - currently running on the default 'tuned' setup - which is fine. Definately a 'must have' if you have a GS with modified exhaust etc.
I installed the controller on a 2007 R1200R with stock exhaust and a K&N air filter. The installation was very easy and the setup was also easy to do. The bike does seem smoother and has greater power. The fuel consumption is also greater. I took a 400mile day trip through the mountains of SC, NC, Ga, and Tn with and without the controller. Without the controller I averaged 52 mpg. With the controller I averaged 44.3mpg. My average mpg during normal riding was approximately 50 mpg. During my rides in the mountains, I intentionally kept the RPM's between 5K and 8K. During normal riding, I am usually below 5500 RPM. With the controller the bike turns 3200 RPM at 60 mph. Overall I have enjoyed the controller. The setup seems to be spot on even without a dyno tune.
R1200LC - Awesome performance upgrade
Purchased the Performance Controller beacuse of positive reviews on WWW.chromeheads.com. What a huge difference. Set controller to recommended setings for a high-flow air filter. Now the acceleration and feel in 6th geer at between 3-35000 RPM is much stronger. It doesnt feel like it is "lugging" anymore. Additonally acceleration in all gears and RPMs is enhanced. It also was effective at removing some of the rumble upon deceleration w/ an aftemarket Ztech exhaust (no catalytic converter. Highly recemmended.
