How it Works



This Information is in two versions - Right now you're on the "Compact Version".

If you want to know all the details, Click "Full Version" to read the original notes from the BoosterPlug inventor.

The "Full Version" is extensive, but very interesting reading !






The BoosterPlug concept seems really simple and our extensive "How it works" pages have inspired a few entrepreneurs to produce BoosterPlug copies.

The button below will provide an owerview of the different "solutions" you will find
- and why you should stay with the original BoosterPlug :-)




 

A short presentation of the BoosterPlug


The BoosterPlug is accepted worldwide, as a brilliant and affordable way to cure the fueling problems that haunts all modern fuel injected Motorcycles.

No need to spend a small fortune on complicated multi adjustable electronic devices like the Power Commander + endless Dyno hours, to make your bike run as it should have from the factory.

The BoosterPlug is installed in less than 10 minutes. It plugs directly into your bikes wire harness using original connectors – no cutting or splicing.



A true Plug and Play solution that will make your bike so much better:
  - Improved and softer throttle response when rolling the throttle on-off.
  - Enrichment of Air/Fuel mixture when you open the throttle will improve acceleration.
  - Remove the Jerky low speed running that is typical for modern lean burn engines.
  - Stronger and more reliable Idle.
  - Reduced Puffing in your aftermarket exhaust on engine braking.



Real plug and play tuning for your BMW, Triumph, Husqvarna




Too good to be true ?

A lot of Plug and Play devices will promise wonderful results, but unfortunately most of them are pure Snake Oil.

The BoosterPlug is the only Plug and Play module, that is properly researched and developed - and performs as promised.

Sounds too good to be true ? - Read on to get a proper explanation - in stead of slick sales talk.

More important - Feedback from our customers is extremely positive.





How does it work then ?

  - If you can trick the Fuel Injection ECU to think the ambient air temperature is lower than the actual readings,
    the ECU will richen up the injected mixture by a certain amount.
  - The correct enrichment will greatly improve the driveability of your bike
  - Basicly, it is done by adding some extra resistance to the Air Intake Temperature Sensor, and the method
    have been tested throughly by many independent sources and it actually works. No magic involved :-) 


The serial resistor tuning trick





  - BUT, the Air Intake Temperature Sensor is not a linear output device, and if you just add a fixed serial resistor like in the
    picture above, the performance of your device will vary a lot with changes in ambient temperature.

  - See the poor performance of the serial resistor in the chart below.


Poor tuning attempt

This is what other Plug and Play devices do, and that's actually why they fail: Typically, they are made to perform well in 20 degrees Celsius (Ambient air temperature), but this will make the bike run lean in 10 degrees, and rich in 30 degrees.

Most of the competitor device manufactorers don't bother to inform you about this, or they may not even know what their device does.....
Other will try to hide the problem in a lot of pseudo-technical talk and fancy buzz words.





The intelligent solution !

  - The BoosterPlug is the only Plug and Play device that offers a stabilized enrichment of the mixture in different ambient temperatures. 
  - To do this, the BoosterPlug is using an extra temperature sensor (and a few other components), that will work in cooperation with the
    original Air Intake Temperature Sensor.

The BoosterPlug sensor makes plug and play tuning work as it should.

  - Sounds pretty easy, but the calculations to get it right are rather difficult. 

  - See the actual performance of the BoosterPlug on the chart below. Note that the enrichment is the same regardless of ambient temperature.
    You'll notice that the horizontal line drifts a little in really extreme temperatures, but it's really insignificant. 

  - This is actually a very good result :-)
