Accelerator Module

WELL NOW..................... :augie let's see :beerjug: ... erm....... erm........ :D now what did I drink again..... aha it was that amazing 18-yr old Glenmorangie :augie

will find out for you - wasn't me that did it. However I was told that the Lamda sends a voltage up to 800mV to the ECU and you need to get it to have a maximum output signal of 500mV - this could be done with physically closing some of the Lamda probe sensor holes I believe... BUT will find out and post as soon as I can get the info. :thumb2

Cheers Goose, all info is valuble :thumb2

Jeez great mind think alike...............

Have downloaded similar info for you, but what this chap told me was that even using one or two washers to "raise" the sensor out from the exhaust in fact works. I have posted a graph as well showing the range up to 800mV - he says to get it to give a maximum reading of 500mV.

I would personally go with the spacer option, unless you have a spare set of Lamda probes that someone with a Oxy-set could use to maybe braze a couple of the holes closed? But carefully as I do not know the heat-limitation of the device.

We were chatting today and using 2 x galvanised washers would also do the trick. Nice thing is that one can add or remove easily!

is that 2 for each sensor. what is the combined thickness? and will you please post your mV reading when yours is done and your comments on performance.

i have an 06 GSA. it seems alot smoother on acceleration, but when on idle, say at a red light, it seems to idle a bit rough. might just be the location of the temp sensor. any ideas?

Both Lamda's will get 2 washers each.

Jeez - my bikes running leaner than a teenage anorexic.

Without reading a gazillion pages on here and assorted other websites, what does the descerning 1200 rider buy that doesn't cost a smal fortune?
 
So having run around with the MK1 for around 300 miles... I took it off today and went for a 2 up jaunt around Derbyshire....around 130 miles in all, and around 20deg C I'd say....

Bike seemed a bit..... woolier than I recall with the module fitted.....

Now the question I need to know... before it goes back on ( 2009 GS)... Is it likely that the module is going to cause any form of damage over time?

I don't want to plough through pages on the subject, and I think this modifying the Lambda probe has muddied the water a bit... as I'm not going to the trouble of doing anything to that :confused:

Can I ask what the benefits are in modifying the Lambda probes?

The page linked to… http://www.energeticforum.com/renew...odification-using-spark-plug-non-foulers.html suggests the mod makes the bike run leaner?

Ebbo - just remember that modding the Lamda's on their own was not the issue. When using the ACCELERATOR plug, the Lamda's need to be changed/modded.
The Accelerator's basically a Resistor that decreases the signal voltage from the airbox to the ECU.... so now the bike thinks that the air is colder therefore should add a bit more fuel, however teh Lamda checks the O2 levels coming out of the engine and wants it to match the "signal"that the ECU rceived from the Accelerator - so ideally the Lamda should "sniff"less O2 otherwise teh ECU tries to compensate all the work the plug's trying to do

Being a numpty I thought the lambda only came into play when the throttle is at a constant opening, and the accelerator module affects the fuelling only when accelerating.....:confused:

That is my understanding too - the lambda sensor takes awhile to catch up, otherwise using the accelerator module would significantly increase fuel consumption - which it clearly does not.

That is pretty much what I thought too - But I'm always open to ideas, open mind and all that...

I fitted mine the other day and took it for a squirt on the weekend. Mine is a 2006 model with a Staintune muffler. The bike feels a lot crisper on acceleration now and has lost the woolly off idle feeling that it has had since fitting the Staintune muffler. It actually struck me as being a little too harsh and rough under acceleration, although the bike needs a bit of a fettle after coming back from an 8000km trip recently. Its winter here too and the day was reasonable cool, maybe around the 25°C range, so I don't know what an Aussie summer will do for it. Seems to be little money well spent though, so far.
 
150 miles around the Peak District on Sunday, no module , two up .... computer says 47mpg

150 miles around the Cotswolds yesterday ... module, two up ... 48.8mpg

Still no comments on the effect on the engine long term.... but earier concerns seemed to centre on too much fuel washing the lubricant away..... now 1.8 mpg more could hardly have an effect :confused:

if you are getting 1.8mpg MORE with the module then it stands that more bore washing is occuring on standard bikes!
