So why all here say hilltop is the best, maybe all have bad bikes.
I have no idea, but you pays your money and you make your choice. I have no experience of the tuning firm that you mention, and i wouldn't use one anyway. Each to his/her own.

But at times so called logic can me misleading . Having knowledge can sometimes override the ability to be understanding and perhaps be pedantic in some replies to honest and unproven questions .
Take for example the different BP part numbers .
All different for the 1150 , 1200 , lc1200 and now the 1250 . There’s the question , they must have differences not the painted picture of instant failure noted by some . So it would be fair to say that the new one still works . I’m still trying one as it’s easy enough to switch around . Difficult to judge yet but let’s see . If I’m wrong I will hold my hands up and tip my cap to the informed logical posters .

What's the point of an original air temp sensor if the ECU over rides it's information?
Great explanation as usual.
Yes but when you do not want to sea you are blind.
How does the saying go?
"You can lead a horse to water, but you can't make it drink"
The reason that we are still talking about this five pages in is because a) some still don’t understand how the BMW ECU works, or b) because my experiment to measure the negation wasn’t fully read, or it wasn’t understood, or c) because you believe that if 45,000 units have been sold (nearly $7M US) that it must work.
There is no need for logic or feeling in the case of BoosterPlug. It’s claim that it shifts the IAT 20C (if the probe is positioned properly) is true. You can use a GS-911 and directly measure that. I have published the results many times
Boosterplug’s claim that a 20C shift in the IAT causes BMW bikes to enrichen the mixture 6% is true. I have measured the effect and published the results many times.
BoosterPlug’s claim that the BMW ECU doesn’t have Short and Long Term Trims is FALSE. I have set up experiments (read all the experiment steps in the link), measured the results and published them.
BMW’s claim that is uses Long Term Trims is TRUE. The Long Term Trims are in various GS-911 logs, you can see them for yourselves. BMW ECUs calculate a table of Multiplicative and Additive Long Term Trims.
If you disconnect the O2 sensors at the same time you install the BP, the added fuel will be permanent. But as soon as you connect the O2 sensors the effect goes away.
Here is the link with the concrete measurements that show the existence of Long Term Trims: https://advrider.com/f/threads/2004...-af-xied-for-bmw.749080/page-40#post-23675190
I repeat: understanding that the BP has no long term effect (more than a tank of gas) does not require any sophisticated or tricky logic. It is easily measured and not with one’s feelings or seat of the pants (the calibrated asshole theory ) but with simple measurement instruments (a Wideband O2 sensor/datalogger).
But one tank of gas (petrol) then a coffee the theory may repeat its self , I’m not after long term gain , just the time the plugs adjusts the initial performance and does the same correction again ,time after time ..like I say I will ride it , swap bikes , coffee and discuss
Has anyone tried one on the new 1250 GS as they now make one .
The feeling is great already but maybe could be made better as the device riches the mixture on a monitored system , similar to tunning houses making them less lean , but without the ecu remap route.
Stick
Let’s leave this as a BoosterPlug thread ...
Managed to get out today on the bike , felt bloody great . Then rode back on another bike (1250) and I was surprised on the difference , mine seemed better , the latter not. Maybe a placebo pill , but I asked the the other owner to try the same , and he agreed with me . I know some will disagree but it felt better and sharper .
The bike swap was due to a new bike , so these two bikes are similar same year , same end cans , same style of rider except the plug ……I may have not have published a paper on this but two fellow riders chatting seemed to make me think different.
I have no idea what you are saying.I'm happy for you that you like the BP.
As for how the engine react to it, it's a different story.
I'll show the readings from my 1200LC GSA (the 1250 is more complicated to read due to the wide band sensor, however since both ECU's acts in the same way, the information is relevant)
Here is the fueling in closed loop, warm engine, no modifications.
The throttle is blipped at 3 seconds and opened at 6 seconds and held to 10 seconds.
---------------
This curve shows the voltage to AFR values from the O2 sensor.
--------------
Then we added the Boosterplug, and this reading is from the very first run, with the BP freshly installed, (i.e hardly any adaptions at this point)
The engine is warm, and the throttle is opened up at 10,5 seconds and helt until 18 seconds.
In both cases the fueling oscillates between rich/lean, and no visible difference in the fueling.
-----------------
Sooo, what does a real richer fueling looks like?
Here is the very same engine with an O2 manipulator added:
Red curve is the voltage from the O2 sensor, while the blue curve is the signals sendt from the O2 manipulator to the ECU in order to make the ECU deliver a richer fueling.
I have no idea what you are saying.

Your wiggly lines may mean something to some but not to me , sorry but apricate the reply , but I cant work out if its good or bad.

I said the plug from riding the bike (1250 gs ) seems to make a difference , sharper , I have no graphs etc just feels better , and it was not only me.
