Accelerator Module

[Yonkyo]

I fitted one of these yesterday.


It’s called an Accelerator Module (i know it just looks like a piece of wire...but).

Quote:
“It is a module I developed to give the R-boxer a smoother acceleration. The motor picks up much nicer at lower revs, motor is more fun to ride. For more info you can surf my website.

Normally the motoronic module reads temperature and is one of the main parameters to determine how much fuel needs to be injected. This only during acceleration of the bike. Once at constant speed, the lambda sensor takes over. Now by cheating the temperature by 20 degrees C, there will be more fuel injected only during acceleration, with the lot of benefits as a results.”


Well? I need to go for a proper long run really, but my GSA definitely felt different.
Throttle response felt crisper and more like it was connected the rear wheel. But what was immediately noticeable, was that I could pull a higher gear from slow speed… e.g. A corner where I always use 2nd gear, I could now use 3rd gear without any complaints from the engine.

In summary…so far I’m impressed.
It’s too early to give a comparison on fuel consumption yet.

09 GSA with Remus headers, standard can and air filter.

Ok, i'm interested so it’s going to enrichen the mixture a little I presume,

How’s it affect town running/slow running, good?

Where from – how much…

It is just a resistor.

costs about 30p and the cost of the plugs.

 

[Yonkyo]

It cost 29euros inc. P&P, which i figured was worth the gamble.

You know the value of the resistor needed and have tried this then...

Oooo - I see a market appearing for 'custom maps' £50 a time.

my 20min test was part town and motorway.
The engine felt noticably more tractable at low speed, i.e. when filtering through traffic etc.

like i said, I need to go for a longer ride, but it seems to do what it says on the tin, at a fraction of the cost of the Power FRK module etc...

Don't know the actual resistor for the 1200GS but this is a well known way of 'fooling' the ECU and has been used on cars for many years.

The resistance of the OEM system changes with temperature and this is used by the ECU to determine how much fuel the bike needs to get started etc.

This 'Accelerator' puts a fixed resistance in the path and therefore the engine thinks the ambient temperature is always cold.

There used to be a down side to all this in that too much fuel was pumped into the engine in certain circumstances and would wash the cylinder bores of its lubrication.

I suppose we could ask Yonkyo to put a meter across his old sensor and the new one after they have been sat together to stabilize in temperature…

I’d do it for you Yonkyo, but I’m 200 miles away LOL

Anyway, I think 29 euro for a plug and play fix like this is good enough value

Perhaps only if there is no nasty negative effect on the engine after you have used it for a extended period of time

The risk ‘as they say’ is entirely yours

Awe well, there before the grace of God go I…..
Always, a risk one takes when you are an early adopter of new tech.

Watch this space…

According to the chap selling this item, it makes the ECU think it is 20 degrees colder than it actually is rather than being fixed. I guess he has worked out that this temperature difference is enough to add about the right amount of extra fuel?

I hope it works, as he will be able to knock out a load of them.

I'd need Dyno proof

Exactly!

I will be testing Accelerator & Power FRK on our dyno next week when I can try both modules together.
The tests will be carried out back to back to get an accurate comparison.
Will keep you informed

It would be usefull to run the €37 ReCyclizer against the others at the same time

For a well rounded report...

Thanks Motoech

 

[Gruffalo]

ill be keeping a close eye on this thread, been looking at getting some new headers for the gs, but if this will do pretty much the same thing for £30, then im all for it!
