Accelerator Module

[mavn]

I had intended to write an appraisal for each device but I can’t it’s just too difficult to write down what is a very subjective thing, in the end it’s just a feeling you get and I was unable to describe it in a meaningful way (I did try).

What I can say is I rode the bike for about 2 hours today with the tank side panels removed so I could swap between the standard set up and module enhanced mode, in all I swapped about 6 times and every time the bike was best with the Booster fitted.

Fitting the AccMod improves the ride as others have described in earlier posts but the best ride is with the Booster.

So is it worth spending the extra, in my opinion yes.

An Offer.....
If there is a local Tosser who would like to try theses on their bike for a few hours and then add their thoughts on here PM me to arrange a ride out. Can’t say fairer than that!

Magnon, thanks for the feedback. It would be interested to see what the fuel consumption will be with the Boosterplug. The main difference could be the selected value of resistance at a given ambient temperature. That the NTC is mounted externally or internally doesn't matter too much (IMHO)

My accelerator mod arrived yesterday(ordered on 13/12)which I thought was quite good for time of year. It was quick and easy to install. I took it for a run today over the same route I took a few days ago of approx 80 miles to compare(fast B roads and a few town centres). The difference was immediately apparent, generally smoother in all situations and even better to ride than usual. MPG on the exact same route went from 50.4 to 52.3. So from my initial impression, another very satisfied customer!

My first post on this site but just to say I'm another staisfied customer. I ordered on 18th December, it arrived this morning, a lot quicker than I expected, and I fitted it this afternoon.

Just on starting it up in the garage I could tell the difference as the pickup off idle is noticeably smoother and less snatchy and that carried through into riding generally. I didn't try any town work but I imagine that's where the improvement will be most obvious, as hopefully it should cure the horrible on-off throttle response. I think it's the best money I've spent on the bike so far.

My Accelerator Module arrived today and fitted it without any problems. Took it out for a short ride but conditions were poor, 3 - 4C and light rain, and visor misting. Bike is an '08, with Pipecraft headers, standard can and filter.

In today's conditions it was hard to detect a dramatic difference but the bike felt good. It seemed very willing and responsive and even in the rain I enjoyed the ride. I had a sense that it was pulling smoother in higher gears which was good for cornering in the wet, less risk of spinning out. Looking forward to trying it out in better conditions. I wish it had it fitted while driving along the Croatian coast road in July, for overtaking all those cars and coaches.

This needs more time and better weather to evaluate properly but I'm not planning to remove it in the near future.

Nice one Adie

Welcome to the forum Chris
Loads of really useful info and stuff here ain’t there.


So, the current consensus of the Accelerator Module.

39 x Accelerator Mod orders confirmed by GSers on this thread.
25 x Positive reviews after road tests
14 x Awaiting delivery/road test feedback.
0 x Negative reviews after road tests

It seems that this little device gives significant benefits to most 1200GS's, regardless of age and mods.

Happy New Year to you fellow GSers

Impressive. What's the overall experience for those with 1150s?

Put my order in today we can test them on the way to Morocco

For 'The Laughing Mole'.

All of my comments have been w.r.t. 1150 useage.

Basically an echo of what the 1200 chaps say. A different (better) 'bike.
I have been using higher gears for a given route and overall it is much more flexible / less fussy. Fuel consumption? Haven't measured it. Definately isn't worse. I do feel I'm being kinder to the drive-line: less shunting / shock loading during throttle on-offs.

V. pleased.

 

[chipsonfriday]

As an 'early adopter' of the Accelerator Module I must say I am extremely pleased with the results. Even more pleased that so many other GS'ers have also found the module to be a brilliant benefit.

I just want to take the opportunity to wish MAVN the best in the new year and every GS'er that has his great product. Such a simple device (despite the technical discussion over who's is better) at such an affordable price has just got to be acknowledged as one of the best mods that can be made to a GS (and RT). Well done MAVN.

Just look at the response to Yonkyo's original post to see the interest it has stirred up.

Happy New Year and great riding in 2010.

Some thoughts

It seems this thread will go on forever, that’s great as it generates so much discussion. I will soon be ordering a unit but whose? I have read a lot of threads on many sights over the last few weeks inc Adv Rider and others which I should of bookmarked for referencing.
My conclusion is:
You have a choice of 3 units, Accelerator module, Booster Plug and Power FKR module. Each is priced differently from a low £27 up to US $300. They all basically operate the same way but vary in suffixation.
The immense technical discussions about resistors and the desire to understand the principle behind the module’s operation could be confusing the issue.
Basically WHICH ONE IS BETTER? Well there is a simple rule; generally you get what you pay for!
Magnon through his testing showed that the Booster, in his opinion, performed better than the Acc Module. The thread on ADV rider had a big positive response to the PKR module.
So which to buy? Looking at the websites of all the module suppliers Accelerator Module is informative but basic. Booster Plus is very comprehensive in technical details and general information FKR has many dyno graphs but is short usable information for the layman.
My choice will be the booster plug as I feel it does a better job overall, appears to be very well researched, developed,tested and the price is reasonable for what you are getting.
Just to throw a spanner into the works , I wonder what the extra money for the FKR will get you????

Safe Riding
Clive.

Clive, You have the Italian, the Belgian and the Danish products listed.
The Dutch have their 'Recycliser', too. Sorry for making your choice even harder.

It seems that they are all good. And in the end, I chose one the cheaper units that does the job. (Very pleased with it, btw.)

We'll have to wait and see whether a definative good, better, best - consensus emerges. And even then, that might subjective.

 

[Beemerman59]

I have just ordered an Accelerator module as I figured for the price it's worth a try at least. If it cures the jerky low speed throttle response and nothing else I will be happy. Price goes up on Jan 10th to 32 Euros (plus Paypal charges I guess) which would still be one of the cheaper mods you can get for a GS.

I heard about the Dutch one but could not find much information about it in English so I left it out. Yes, I agree the Acc Module looks and sounds good., and excellent value for money. and if i was in the Uk I would probable buy one. Temperatures in Oz go from winter in the south, say 0'C to 40'C plus in the middle of summer so this influenced my choice of units for its flexibility.
Just how much better is the Booster than the Acc Module? Is it worth the extra? we will just have to wait and see as you say

Clive,

if you're getting an acc module sent to Oz, don't forget to factor in €30 for postage, which makes the price not far off the USD120 delivered for the Booster Plug in the group buy in the vendors section over at Advrider,

me too

hi,after reading all the favourable comments i too have ordered one of these leads-i just hope it doesnt knock the mpg much as i do value my bikes economy,time will tell.

 

[DutchBryn]

Cheers Clive. Please don't confuse No. of posts (from me) on this thread for expertise. I can only say how something's worked on my bike, and for where/when I ride it.

I took a 'view' after reading through Dutch and Flanders forums. Both Rec. and Acc. units seemed good. One came out slightly later (possibly?) benefiting from development lessons of earlier one. At this price, don't expect folk to book days at the MIRA test facility.. So it helped (me) to pick one that had been developed in an area where I ride a lot. And for me, zero to 40 is fine.
The Dutch are the proud Scots of Europe, so cheaper is better (and not worse, for me) ;-))

From my experience your mpg will drop. I'm now down to around 43mpg where once I was getting up to 52mpg. BUT the temperature has changed and I thing this has alot to do with it. I don't know where the others are coming from when they say their mpg have increased when mine has decreased running similar bikes. To get a better reading you have to reset your mpg reading and then wait and see.

Could it be because they are fannying about in the lower rev ranges testing if the module does anything?
There could well be some fuel economy to be had out of one of these modules but I think some of the claims are a bit wild to the point where some are claiming nearly a 10% improvement. The computer isn't a very reliable means of testing it either. Its ok for a rough tank range but when it comes to +- 1 or 2 MPG its not the best.

I haven’t ridden mine in these freezing temperatures (been over in Spain). But two of my mates have also reported increased fuel consumption. So I’ve suggested they disconnect the Acc. until the big freeze is over.

Lucky you Yonko - but I bet it was cold coming back

I must admit, when I ride my bike I'm out for a bikers ride rather than riding around town or in traffic. During 2009 I started an advance motorbike course where I now ride slower to speed limits quite strictly but I do accelerate hard between speed limits say going from 40 to 60 for example I will open her up as hard and fast as it's safe to enjoy the thrills of riding a bike within speed limits - always amuses me leaving streaming cars behind me! This may account for low mpg but having said that I still used to get late 40s early 50s before?
