which one is the easiest to install and which one would you recommend
New Accelerator Module tested

aah, could not wait for reply, so have just ordered the extended module. now i cant wait to plug and play.
And still only half the price of the booster plug, which essentially the same thing apart from a fancy resin box
Both products are simple plug and play (see photos on my first post). The only difference is the extended version has the extra cable which you can route where ever you like (preferably away from engine/exhaust heat).

Mine arrived today and installed in my 2007 R1200GS Adventure with 38,000+ miles.
Recent valve adjustment and rocker arm adjustment. Still running the original spark plugs (old ones look fantastic,fuel mileage still the same,new one's waiting to be installed at 40K).
Test run of 20 miles in city and on highway.
Today,cloudy 67°F, 82% humidity.
No real significant change in acceleration or idle on side streets at speeds of 20-45mph. Stop n go driving seemed the same as before plug install.
High speed driving @4000rpm's, little less vibres in the bars,...but still no real big difference with or without plug.
I must say,my bike has been running flawlessly. I always keep it in tune,use premium fuel,ride it spiritly but don't beat on it.
All in all I'd say a 10% improvement but that's about it.
Will test futher this weekend.

Mine arrived today.I have a 200ml run arranged for tomorrow on varying roads,so I will let the collective know my thoughts.

Today,I did 300 miles of highway 70-80mph's and back roads 25-55 mph's.
Also was accompanied by a buddy with a 2006 GS Adv "Non-modified/stock" bike. We switched bikes several times to compare.
Startup's from complete stops I or we couldn't tell/feel any power differences,only that the bike did feel a *tad* smoother.
Accelerating in turns/sweepers/straights again at different speeds,everything pretty much felt the same from bike to bike.
Only difference we agreed upon tho,was with the Accel-Plug the bike/engine was definately smoother and especially at highway speeds.
But remember my bike with the Acel Plug has 38K+ miles and my buddys bike has 24K miles. So maybe my engine is a touch more broken in.
Monday I'll fill the tank and record gas mileage.
Did 247mls yesterday 2up varying roads some town riding.
I found the bike to be much smoother when riding at slow speeds through towns in traffic etc.
The only other difference I could feel was that roll on acceleration in any gear was significantly smoother.
Worth £30?
Definitely IMO

It sounds like your bike is running pretty sweet anyway.
It seems that the most benefit in fitting the Accelerator, is felt by owners of recent 2008/9 GS’s. These appear to have a very lean fuel map as standard. Older GS’s would seem to run richer, so the difference in performance is not as noticeable.

Last nights fillup was 6.26 gals,travel was 278.4 miles which comes out to be 44.43 mpg's. Riding as described above. So,pretty much the same mpg's as always.
I think as a one more time experiment,I'll remove the *plug* and see if any changes in smoothness,power and mileage. It only takes a few minutes to do this.

Combined city lo and medium speeds with stop n go's..nothing really too noticeable. Maybe a slight lessening of vibe's on the throttle hand but thats about it.
Highway driving...definately a lessening of the buzz in the throttle hand at 4000 rpm's. And so that might be a determining factor for those who wish to purchase.
Accelerations 'bout the same,but really hard to tell if any kind of performance gain.
Resistance readings taken on the plug unit shows .4 ohms at 78-80°F.
.9 ohms at roughly freezer temps for 5 minutes. In the sun at 85°F 4-5 minutes .2 ohms.
In closing...unless the bike is put on a dyno in a controlled environment,*seat of the pants* info is about all your gonna get/feel. Again a placebo effect could/will affect outcome.
Goodluck to those of you who choose to purchase one.

Also to be taken into consideration is the newer models (I believe '08's and later) have different cam setups,transmission gear ratio's and taller rearend ratio's. Probably to help make up for the "bottom end loss" from leaner/tighter emmision laws.

Just a bit of info wrt the Accelerator.
On the Dyno tests we did, it was found that while the Temp inside the Dyno was 24deg C, the addition of the Accelerator module (connecting the bike to the 911 Diagnostic unit) then fooled the ECU into believing the Temp was 17.3deg C.
Now this is great as the drop in Temp should tell the ECU that it's colder and therefore the air is more dense - therefore add more fuel.
The big problem was that when we connected the bike to the Dyno and the 911-plug we found inconsistent behaviour of the engine.
The graph looked like a spike on steroids..............
Then we realised what the bloody culprit was........... the Lamda sensors!
The Lamda measures and "sniffs" the mixture coming through the pipes and then tells the ECU to ignore the reading gotten from the Accelerator - and the ECU then tries to compensate.
In theory if the Accelerator module is connected - have the Lamda sensor modded as well to sniff less air - which would then give you a substantial improvement on the way the Accelerator affects your bike!

Having read everything, it appears that only owners of 2008 and 2009 models will benefit most from the Accelerator Module. I ride the older 2007 model and presume that it may be different in terms of emission settings due to emission laws. However, I wonder if it still improves the 2010 model which has a smoother OHDC engine with more torque at low revs than the preceded models.
Feedback from 2007 owners would be appreciated though.

Mine arrived and was fitted today in less than ten minutes.
I'm off on a 3500 mile wo up trip down through France and into Spain next week so should be able to post some observations re: performance and fuel economy when I return. Mine's a 2005 model.

just got mine today, 06 GSA. where is the best place to put the sensor, in front or rear of bike?
The mk1 version has been on my HP2 now for couple of months and it just smoothed everything out escpecially on low tick over revs doodling between traffic. Only recently with warmer weather I noticed that the power has definitely increased slightly as I find wakcing the throttle open finds me most times with he front end in the air 
Fuel consumption has neither dropped or improved really. I might try the new version out and see whether it affects the bike in any way. If you have £30 spare and nothing to lose go for it
