THE TRUTH about the Booster Plug and Fuel X! What do they really do? Which one do you need??

[@karlsquire8148]

FYI, the Booster plug does not work with Euro5 ECU so if your after 2022 probably wont work you'll get an engine light some 2022's have the euro5 computer in them my 2022 did not.

[@shamikmazumder2333]

try fuelX

[@karlsquire8148]

Thanks for the vid. I also have: DNA air filter, Emgo Hooligan slip-ons and I have the booster plug. I love the way my bike runs. it feels like it runs as it should, booster plug make a noticeable difference in acceleration, not more power, well maybe .00001 hp more lol but mostly just a very nice acceleration, just rides really nice. by the way my bike sounds exactly the same as yours. a great tell that the booster plug is working well is the plug colour, with the booster plug the spark plugs are a very nice slightly darker in colour.

[@jewciferrides]

I agree on all points, and it seems great minds think alike! Good call checking the plug to verify. 👍

[@karlsquire8148]

The bike is supposed to crackle and pop, you just notice it more when you change the pipe because you dont have mufflers to muffle the sound. The crackle and pop is the CAT burning off unspent fuel.

[@jewciferrides]

Very true! Just a bonus that it sounds awesome 😎

[@karlsquire8148]

@@jewciferrides lol ya great minds do sound alike, I love the sound in Deceleration as well.

[@SeamusMacMattain]

ummm mine didn't pop until I removed the stock headers for the open pipes from Hitchcock's, so it isn't just the cats causing unspent fuel to burn

[@karlsquire8148]

@@SeamusMacMattain yes it is but with the stock pipes, they are mufflers and they did their job, they muffled the sound of the crackle and pop.

Useful information. Thank you. And I love the Huntsville area.

interceptor in stock setup is capable enough to pull even from 2k rpm. I have installed fuel x pro, dna filter, free flow exhaust. overall it seems not worth all these changes. not noticeable difference and definitely it won't convert royal enfield to triumph st900. I regret all expenses considering I am now going to upgrade to triumph. Anyone owning interceptor, has slight chance to upgrade in few years, don't waste money after the performance mods.

[@HaggisPower]

Yep, very little if any performance increase with all those changes. I sent my booster plug back for a refund. I have dropped 14kg from the weight (which is probably the most significant performance improvement). Fitting a LiFePo4 battery when the OEM one dies is probably the best bang for buck in that regard.

[@TheBigBlueMarble]

Royal Enfield configures their bikes to run as lean as possible in order to meet emissions standards. They are so lean that the idle on many of their bikes, especially the Himalayan, is a problem. Even RE recoginzies this and they have added a "choke" that allows the rider to richen up the mixture manually by holding down the choke button.

[@mijithebub]

Kawasaki has an enricher on the FI Mean Streak 1600. Its odd to have a "choke" on an FI bike.

[@TheBigBlueMarble]

@@mijithebub If Kawasaki is also selling their bikes very lean, a choke makes all the sense in the world

Great video very informative.

[@jewciferrides]

Thanks! It's a confusing subject, hopefully I explained it well 😅

[@TheBigBlueMarble]

The FuelX Pro provides 10 maps (9 actual maps and a stock setting). During open loop operation, and in differing riding conditions, I don't see how a rider can reliably select the best/most effective map. Can someone explain how those decisions can be made?

[@jewciferrides]

FuelX (all modelsl work in closed loop mode, when the ECU is listening to the O2 sensors, inserting various amounts of false lean (or rich for 1 and 2 on pro) signals for the ECU to make corrections. Closed loop is idling and cruising with stationary throttle. So if someone had made their bike, lean through modifications or altitude or otherwise to the point where it was not idling correctly, That's where the Fuel X would come in. The booster plug works in open loop mode, under acceleration and changing throttle position. It keeps the closed loop mode stock.

[@TheBigBlueMarble]

@@jewciferrides I understand the general idea of the FuelX. What I don't understand is how a rider can reliably select the best map, in real time, for the immediate situation. Seems as though many riders just set it at 5/6 and leave it there, which defeats the whole purpose of the multiple maps. Without some sort of sensor telling me if I am too lean or too rich for the current moment, it appears to be nothing more than a guess.

[@jewciferrides]

@@TheBigBlueMarble Exactly. My opinion is let the ECU and O2 sensors do their job for idling and cruising. The only time I would ever consider a Fuel X would be if I'd modified my engine into no longer idling properly. In that case, I'd just find the map that got the idle back to healthy.

[@WaterDR-tw8re]

These bikes are designed to run lean from the factory. No amount of ECU correction can fix that.

[@TheBigBlueMarble]

@@WaterDR-tw8re Not so. They are not designed to run lean, they are only configured to run lean. In fact, they run hot and rough at low RPM when running so lean. This can easily be changed by passing modified O2 and termperature data to the ECU during closed loop operation. They will then run cooler and smoother in closed loop.

[@theradiantchild]

Is it worth adding free flow headers?

[@jewciferrides]

I don't have them so I can't say for sure, but personally if I went full headers and exhaust, plus my DNA intake, I would start looking at more advanced fuel management and tuning than my booster plug or a fuelX would be able to provide. These (and most) bikes run pretty lean from the factory So there's not a ton of room to open them up before they start bogging down.

[@chrispulham4779]

Booster plug doesn't work on the Euro5 2023 model

[@jewciferrides]

@@chrispulham4779 Correct, unfortunately.

[@silverback3926]

Did it affect mileage?

[@jewciferrides]

I'm sure it did to a certain extent, but highway mileage would stay the same as the ECU only looks for ambient temperature during acceleration, not cruising. Conversely a fuel X would affect your highway mpg, as it inserts false lean signals from the O2 sensor rather than modifying temperature.
