Accelerator Module

[Snow White]

I have a standard 06 R1200GS with the module fitted. When i bought the bike I was a little surprised about how lumpy it could be at low revs, post fitting the module It certainly made a positive difference to the ride. I thought it was a good investment and has certainly improved the rideability around town. Only problem I'm currently having is shift work and frozen roads meaning I'm having to take the car to work rather than the pleasure or the economy of the bike (generally between 48-52 mpg)

Appledell, remove the cable from the bike (make sure the ignition is off), set your meter to the ohms scale, readings will be in K ohm, ie 5,000 ohms ferinstance'.

Test across the pins in a plug at one end of the cable (it should be the same result testing in ether of the plugs).


Test each wire from one end of the cable to the other, one of the wires may well be virtually zero resistance so don’t worry.

Good luck, any probs, post up

OK - removed the plug (totally) - On one side total deflection. on the other 1800 ohms

Is this ok?

Has anyone here fitted an Accelerator to a standard bike with original exhaust system? If so, I am interested in feedback on any improvements.

Cheers,

Matt

Hi Matt,

I've got a box-standard 2006/56 GSA, fitted the Magic Wire recently, the difference is clear. No more "jerking" beteween 1st and 2nd gear when the engine's cold.
Much smoother ride.

I’ll try and help, your lower picture maybe trying to indicate zero resistance but the meter isn’t adjusted correctly to show zero. Put the two probes together tightly and turn the adjuster on the right till the needle is indicating 0, ie zero ohms resistance. When its showing zero, try again...

(If it won't go to zero, you may need a new battery).

Hi Martin,

I'm such a knob ed

OK on one side 0 ohms (adjusted)

on the other side 9500 to 10000 ohms (on the same scale as the original pictures -if that makes sense ?)

Thanks

Mike

Hi Martin,


Thanks

Mike

please mail me with any more testing as really it shouldn't be on here. martin dot ebdon at ntlworld dot com or work with maven, its only fair... martin

no major MPG variation

Nope. No electrical issues here. Not heard of any others either.
Fuel consumption is a bit erratic in these low temps tho.

Let us know if your mpg changes.

UPDATE:

Thought I'd give a few figures re: my recent fuel consumption.

My bike:
-2006/56 GSA with nearly 19.000 miles on the clock
-standard exhaust (but I'd love a "TT" Twalcom!)
-no headers yet (soon... I know Sarge...)
-everyday riding in Central London, minimum 30 miles, except when there was 2 inches of solid ice down my road...
-weekly ride of at least 100 miles
-solo riding most of the time, once every 2 weeks with pillion (9 stones)
-panniers & topbox usually full of spare oil/tool kit/compressor/big chain/disc lock/1st Aid kit/etc...
-riding style: not fast, not slow, depends on weather, weekly blast to clean the can...

-Fuel consumption for the past few months before I fitted the Accelerator:
best: 11.37 miles per litre
worse: 8.32 miles per litre
average: 9.18 miles per litre

-Fuel consumption AFTER fitting the Accelerator:
best: 10.74 miles per litre
worse: 8.28 miles per litre
average: 8.75 miles per litre

Sorry I haven't converted in MPG but that's how I keep track of my pit-stops!

No major difference.

THANK YOU again Mavn!!!

That is what I experience as well. Slight increase in fuel consumption up from 6.2 to 6.5 l/100km

Accelerator Module on a HP2e

ordered on the 17th of Feb 10 and it arrived in lil ol ireland 2 days later
will fit today

I have also experienced increased fuel consumption during this cold weather.
From approx. 47mpg Av when 10c+ temp.
to approx. 43mpg current Av in 0c - 8c.

Engine still performs wonderfully though, so not i'm not to fussed about paying for a little extra gas.

 

[gavb0]

Mine arrived today will fit this afternoon soon as the snows gone i will post my findings

 

[Trevor Phillips]

And another buyer

It turned up this morning, ordered Sunday night. Not bad from Belgium. 10 minutes to fit, with the wife mouthing off holding the umbrella. And more than 5 of that was removing the front seat. Tomorrow we see what it does. I might be stupid enough to fit it in the rain, but I'm buggered if I'll test it in this filthy weather.

 

[original_concept]

Please excuse the self quote..

Further to this, just rode 350 miles to Scotland and cannot believe the consumption. A shade under 50 mpg, fully loaded with all boxes and at an average recorded speed of 55 (the roads were OK so I was not slow on the motorways). The best I have ever had was about 45 on a run. Again, much easier to use on the snow covered back roads.

Curious...

A few days ago I was returning down South. Having filled up at Wetherby services at £1.20 a litre!; I decided on getting my money's worth and set out to not to go over an indicated 70mph [1][2].

Well, the damm thing managed 55mpg (I saw 60mpg sometimes, when dropping to 40mph). At the next fillup with 205/210 miles (ISTR) covered I only filled up with another 18-19 litres.

My normal MPG is unknown, coz I never pay attention to it.

This is a stock 2009 spec GS.

[1] uhm.. apart from a little tete-a-tete with a 600GSXR.. teehee..

petrol usage

Just a quick note on fuel consumptioon.

Since fitting the module my fuel comsumption has dropped from 46.3mpg to 39.6mpg, as my bike has shown very little or no improvements, if it stays like this i will remove it, however im not dissapointed at £29.

If you dont try things you will never no

My experience so far as well. But I am going to give it a bit longer. Also agree that not disappointed - worth a go at the price.

 

[rossi46]

surely the fact that the bike is using more fuel must mean that it's not running dangerously lean, hence reducing the chance of burning valves ???

Burnt valves isn't what the 1200 suffers from. A burnt valve looks heart shaped where the heat has melted the head of the valve. With 1200 engines the head completely drops off at the join between the stem and the head, valves are generally made from two parts welded together. Generally caused by too much seat pressure or crap design.

Fist Ride Report

Just returned from riding around Rajasthan, northern India, for 3 weeks. What an awesome trip and I would recommend it to everyone.
This is my first report on the Booster Plug. The first thing I noticed was the slight increase in idle, only slight but I am sure it was up. Secondly the take of from lights and slowing down was less jerky. Gearing down was smooth even when the gear was too high for the selected gear, before it would jerk around a bit. Acceleration is improved, I went to pass a slow car after a roundabout and hit the gas and it almost lifted the front wheel. Quite a surprise. Next, the fuel consumption appears to be down but I will need more time to evaluate this properly.
In summary I am very impressed but I will take it for a longer ride on Saturday 2 up and see what happens.

Outside temperature was from 25.5 to 31 degrees Celsius

I've ordered a BoosterPlug from Jens, just waiting for it to arrive.. in the meantime been working through this very interesting thread. FWIW I went with Jens' module like some others because it seemed like the most clear explanation of what the module would do.

So far there seem to have been a lot of positives for both Mavn's and Jens' gizmos and seems like at least within certain temperature ranges they should be kicking out comparable adjustments. Hopefully I'll be able to report good things too and I'll be happy to share once I have the thing installed.

But I'm interested if either Jens or Mavn or some of the techier tossers can expand on why a bike might not respond so well to this mod. It seems from the mpg figures that LBL and PW are both seeing richer mixes with the modules installed but no performance improvements. Why might that be? Is it that the mixes on these bikes are already richer than standard for some reason and the mods are pushing beyond optimum? Seems like it would have to be something to do with engine/intake/exhaust setup rather than something unrelated like a dragging rear break or whotnot which can obviously make a bike feel low on power but would be improved relatively if the engine was suddenly pulling more willingly.

Anyone willing/able to comment?
