New Moto Guzzi Door Mats Available Now
At some point repeating the consequences of running a booster plug and open air filter just seems senseless . It's like the car tire argument , or the discussion about whether we have been to the moon , no one's mind gets changed . Dusty
What consequences are you taking about ? My Guzzi runs better now and thats a good thing .
Do you understand what that booster plug/fat duc thing is actually doing ? Dusty
Please tell me because my bike runs better not worse
The booster plug is a spoofer , it is nothing more than a 50C resistor that is telling the computer that the engine is cold . The funny thing is , on the official Booster Plug website they admit they are selling snake oil , because they call the "other" products that do exactly the same thing snake oil . A proper remap is way more effective , and won't cause the engine to overfuel . There are probably 20 threads on WG that explain the reality of this . Dusty
Move over I wanna good seat to witness the spectacle about to unfold
I've gone through most of these earlier posts concerning the "booster plug " , consensus appeared thatthose that don't like the idea poo pooed them , those that installed them enjoyed them , no remarks ofpeople that used them actually removing them . The greatest criticism came from those that hadn't used them.(not completely unusual ). If it works for you , then Yahoo . These discussions are what keep us coming backto this site , heck, some peoples opinions about tires and seats are different than mine too . Peter
My favorite is still the 100 MPG carburetor , although I haven't heard about one of those in a few years Dusty
Using the word perception must come from a nay sayer , not a user . On another note , please publish the dyno , exhaust gas readings froma dyno'd California or Eldorado . Engine temp readings would be nice too. :azn:Peter
Here's a good explanation by roger04rt on AdvRider.com of how the BMW ECUs deal with the Booster Plug - in a few tankfulls the ECU corrects out it's initial effect. Does anyone know if the Guzzsi ECU reacts similarly? When you install just the boosterplug, it changes the temperature signal sent from the intake manifold to the ECU (Motronic or BMSX). Momentarily, that results in the ECU seeing a cooler air temperature and adding about 6% fuel. However, moments after that, the ECU is reading the O2 sensor, sees that the mixture is too rich and within seconds reduces the fueling to exactly where it had been before the addition of the BoosterPlug (let's not just pick on them, every IAT shifter has this problem). And worse, after enough riding, all the long term trims have fully adjust to the IAT temperature shift and there is no fueling difference anywhere--the long term trims are all set to about 0.94, which is 6% less than 1.00. So the simple math is that the BoosterPlug says to add 6% to fueling and the Long Term Trims say to remove 6% fueling and you end up back at stock fueling. https://advrider.com/f/threads/2004-r1150rt-wideband-o2-sensor-project-and-af-xied-for-bmw.749080/page-112
