There doesn't seem to be much of an improvement with the accelerator on the 20% and 40% runs
It would be helpful if mavn published his dyno results on this thread. I notice there's a 'picture' on his website. Can we see the actual dyno charts ? - ideally with a 40% run if this exists.

where is mine
ordered mine 9 days ago and it still aint here
did you guys have to sign for yours

It doesn’t show it on the graph, but the Accelerator Module makes the bike much easier to ride around town, gets rid of most of the roughness, make it much more pleasant to ride, worth every penny I’d say.Have a look here.

Ah... i might know the answer to that.
I thought mine was taking a while to be delivered, until a nice lady knocked on my door and asked if it was me who uses a BMW bike, i thought opps exhaust may be too loud
but no, the address on the jiffy bad was badly written and my address number even though it should have been 39 looked like 33, so it had gone to the wrong address.Might be an idea to ask any neighbours near by to see if the same thing could have happened.
Hope it turns up.
BTW fitted mine this afternoon but not had a run on it yet.

I will check
Cheers Claw i will check

Sorry to be thick but does this thing fit "in line" once you remove the existing single plug at the temperature sensor? Ta. Mine has just been delivered (very quick) so will test out at the weekend.
I have a device working on a similar principle on my Ford Galaxy which definitely delivers more power and more mpg. It cost me £50 and adds 40-50 miles to every tankful. After 165k miles, I suspect I have had my money's worth even for a 20p resistor.
Mine arrived Monday, ten days after Mavn said he'd mailed it; possibly seasonal volume is causing delays. Anyway, like others I found it quick and easy to fit. Tried it out today and experienced the same improvement others have - noticeably smoother, and more low-end grunt. Also, not sure if it's my imagination, but it seems to sound a bit deeper. Recommended!

I think he's struggling with the high demand for his product. I ordered another one for a mate last week, and i'm still waiting for the postman.
I must say, i cant keep off my GSA, even in the shite weather we’ve been having, i just have to ride it. Its just sooo smooooth and grunty now.

Yep, that's how its fitted, 5 min job at the most
Ta....first job Saturday morning, then.
I have been reading this thread with interest. Can someone tell me if it would be better to run these with the standard Air filter. At the moment I run with Kehinan headers and a K+n on an 08 GSA with 19000 miles of trouble free running.
Do tell ...
... where you chaps are ordering from ? I've read both threads and it appeared to me that Mototech (?) had taken over the supply of these widgets, but I can only find a link to the more expensive widget on their site

tested mine
Fitted mine yesterday and went for a ride today, now i am not the best to comment as in fairness i just get on and ride whats underneath me and the roads were wet and a wee bit slippery, but i could feel no differance at all.
Im not too dissappointed tho cus its propably just me and i havnt ridden the beast for 2 weeks as ive been commuting on my KLE 500, but even if it just helps it run not as lean i will be happy.
I reserve the right to change my opinion at any time

Mine has arrived and my mate is testing it first and he also has reported little difference, but in all fairness it is a 'with cat' version and my mate is on a de catted bike!
My mate is an engineer with particularly intense tuning/tappet/end float/balancing abilities, so his bike is very well sorted without this mod.
I await my test next week

[/QUOTE]Hi I just want to 'quick' react on the dyno performance comparison test with the Power FRK module.
First I want react on the way they write how the Power FRK module works and how misleading the info is...
<<The Power FRK Module works as follows:
It detects and interprets the engine RPMs by the alternator’s sine wave pulsing in the power supply to the IAT sensor
It interprets the rush of air as you open the throttle using the IAT sensor’s variant signal. This is how we determine load.
Using the above two variants the Power FRK Module will modify the IAT signal to call up on-board mapping in the optimal performance range based on the demand of the rush of air into the air box and the corresponding RPM.
THE POWER FRK detects the engine revolutions and the Power FRK comes into operation only when the engine revolutions increase. The Power FRK Module senses the RPM and Pressure changes in the air-box and automatically modifies the signal of the IAT sensor on acceleration only for maximum power.
As engine revolutions decrease and you are running at constant speed (Steady State) the Power FRK Module stops its IAT signal modulation. Your ECU will return to normal programming and will also allow the ECU to go into “Closed Loop Operation” mode when riding Steady State Mode.
Powerful Performance with better MPG/KPL as the combustion efficiency is enhanced by excellent flame front propagation from optimal Injection and Ignition mapping.>>
1) First have a look at their installation instructions (http://www.powerfrkusa.net/setup/bmw-installation-guides/r-1200-gs/). You will see that it is mounted between the motronic module and the temperature sensor. It has also 2 pins in the connector. Just like the ACCELERATOR module. I asked it several times from Mototech to explain how different technology their module is towards mine. Up to now no reaction! So how can the Power FRK module detect the engine RPM, the IAT sensors, MODIFY the IAT signals,etc...??? Their explanation above is just bull... The fact is that it is more or less the same way constructed as the Accelerator module. Check out various forums and they will confirm that it is just a resistor value between the 2 leads. At least I'm honnest in what the module is build off and already wrote this in this forum what is inside.
2) Having explained their technique, I want to make some remarks on the DYNO run. There are already DYNO tests available comparing the Power FRK with other same types of modules. (I can forward the link if needed). These are done by customers who bought such a Power FRK module and not done by their representatives. These results were very close (falling in the same range). I don't understand why the dyno tests were not done using Power versus RPM's, like they are usually done. It is also not so difficult to get better results. Just use different values of resistors. I could have send out a much stronger one to Mototech where the results of the accelerator should have been beter. What these tests doesn't indicate is that if you make it too strong, the richer the fuel mixture become and you will run into difficulties during the riding of your bike (= field test no dyno test), like engine shut-off during (de-)acceleration, hugh increase of fuel consumption,... You can find again this on forums. The filosofy of the Power FRK is that if a customer is not satisfied with the one that has been send, they change it with another one that has another resistance value. (just a thought that came to my mind when I saw the test results: why are there about 50 dyno runs taken? Normally you put the 2 modules in the bike and test it. Was there so many trials needed to find a version that performed better?)
3) The basic thought of the module that I created was to let the engine run smoother in low revs, nicer throttle response, ... I believe many users reports the same advantages... And this for 1/10 the price Power FRK is asking!!! So I don't think more expanation is needed. I just regret that there is no explanation that I'm wrong that their product is also just a resistor and not a very sophiscated technology. Yes it is nicer boxed, with CD...!
