Booster plug?

[YellowDog]

Does anyone have one of thses installed on their BMW?

Basically this chip sits between the airbox sensor and the ECU.

It kids the ECU into re-jigging the mix to give more power and smoother performance.

They now have a model available for my Tiger 1050 and was wondering if there are any happy Beemer users out there for a bit of feedback ?

bump, you've got me interested...

I read some stuff on a BMW site that the Booster Plug addresses some serious inherent BMW issues.

It looks like the cheapest and simplest mod around to get 6% extra out of your bike, plus other benefits.

Think I might just order one and see how it goes.

cool. let us know how it goes

Its a resistor that fools the ecu into thinking its colder than it really is, making it run a little richer , maybe 10% at a guess.

Yep, it would be quite easy to replicate. Measure the voltage and current to the sensor at several temperatures, say starting on a frosty morning, through to a hot afternoon. Then you know the characteristic of the sensor. A simple voltage divider would allow you to then "pick" any amount of "temperature correction" you wished.

Its likely that a modern engine is waaay lean except at start up, so the comment on the manufacturers web page about mixture being quite non-linear is possibly quite correct.

It may be easier to fool the ECU by tampering with the air flow meter - tell the ECU that there is 10% more air than there really is, and t will inject 10% more petrol.

Well I did get the Booster Plug and must say that the difference is quite noticeable, particularly with top gear power delivery.

It also seems to have ironed out the odd snatch issue that I had.

Low cost easy to fit mod with instant gain.

I understand that some manufacturers are starting to fit them as a factory standard.

Why, they could just set them up properly for free. Maybe it's dealers rather than the manufacturer?

I probably didn't say that very well.

My understanding is that they are incorporating the technology of kidding the ECU by measuring the temperature from outside of the airbox. i.e. as you rightly said 'setting them up properly'.

But the manufacturer shouldn't need to 'kid' the ecu, they should just be 'set up properly' from factory ie no extra hardware required.

Having the temp sensor in the right place would be a good start.

But with a richer supply of fuel, then their economy figures might not look so good.
