Booster Plug

[Royal Tiger]

I ordered one for the ST.  I can't wait for spring to see if I can remember what it was like before.  Lol

Will be interesting to see how it does. Might get one for myself if they work.

Fudge tipped me off to them.  Supposedly do wonders so I'm excited to try the bike in the spring, I'm just afraid I forget what it was like before.

One of the first things I did for my R1200R.

They work as advertised.

 . What is it?

My R12ST has no surging, and pulls very cleanly, would there be any benefit to me?

From what I have read (on the k1300/k1200 forums) those that reported their fuel mileage before/after showed a loss of 2-3 mpg.  My K1300s hasn't given me any issues and am perfectly pleased the way it runs so I am not going to mess with it....I do run Techron through it 3 times during the riding season

I don't think so, the reason I installed the Booster Plug was because at lower RPM and lower speeds the throttle transition was abrupt.  You could change the way you ride by selecting a lower gear giving you a higher RPM, but I didn't like the 'on/off' abruptness of the throttle.  I installed the booster plug and it smoothed out the transition, and that is all that I noticed.  Allegedly it helps with starting and some other added benefits but I didn't have any other issues.  For me it worked well and addressed the concern, I didn't notice a loss in mileage.  Since the Booster Plug only works during 'open loop' it shouldn't really affect mileage very much if at all.  There are some alternative products also out there that address the same issue.

There are several similar devices to the Booster Plug.  They all plug into air temp sensor and fool the ECU/ZFE or whatever the bike calls the computer that controls the fuel injection.  I was on the group that tested Booster Plug on Triumph Tiger's.  Without going into a lot of detail, the gismo changes the temp value being sent to the computer and shifts the map.  Most FI bikes have problems at low rpm's and throttle transitions because pollution regulations forced manufacturers to make those parts of the map lean.   The difference between most of the gismo's is how they determine the value being sent to the computer.  Jens who makes the Booster Plug is a great guy and not a snake oil salesman like some of the others.  He makes no claim for any boost power and will show you actual dyno tests.  The gismo, IMO is pretty much for driveability issues (if there is such a word) connected to throttle response.

IMO, and that of several experts (which I am definitely NOT one), all IAT devices are very limited in what they can do, but at least it is easy to instal and you have to go to way more expensive and complicated fixes for things like wanting "mo' power".

By the way they do this same thing on cars and a lot of other bikes.

Thanks! I don't think I need one for my GT... yet!

It got here from Denmark yesterday.  Impressive.  Won't be installing it for awhile though.  Looks simple enough in the directions.
