I just bought a Fuel X lite, thank you for this directions on the intalling preocess. I'm going to install also a mid pipe decat, K&N filter and the DNA lid stage 2. I'm looking to sound improvements and smoothly driving experience on a city 2.6k meters above sea level 😅
Sounds good, you should certainly notice the difference in sound. Even with the Lite I would recommend trying to keep slightly higher revs since the rough running at low revs isn't just fuel related. Good luck with the install of the project!
@@ntdeas If you intend riding at low speed then yes, consider a different sprocket set up - this is what stunt riders do after all, and they do it for a reason. But you also have to be a good enough rider - this engine is not designed to be run at low revs, so you need to mitigate that by improving your rider skills.
@@MotoMirius awesome thank you for the quick reply! I'm subscribed and I'm going through all your vids and liking them for sure. I'm not going to change the sprocket as I do ride on the interstate from time to time where the speed limit is 80. If the bike doesn't like lower revs, I'm just going to keep it at higher revs for now when practicing low speed stuff and maybe think about getting a fuel x lite at some point (maybe). Right now my biggest problem is stalling sometimes after doing a stoppie when the rear tire gets back on the ground and I'm trying to take off real quick without ever putting my feet down. I don't stall doing this drill with other bikes that I have more muscle memory with. I just remind myself to be more patient/focused with the Duke, stay relaxed with my upper body, squeeze my knees against the tank a little tighter, and give it a little more gas while slipping the clutch out than I normally do. When I do that I don't stall after the stoppie and keep going just fine and I'm doing that more often than not now. Just reworking my muscle memory a bit I guess from past bikes. I like the idea of the fuel x but if the engine wasn't designed for lower revs I guess I won't force it to work there artificially and just get used to it how it is like I have been.
I would assume that when a bike has to go through emissions testing (as required in some countries), you should set the FuelX Pro back to stock (Map 3).
Why are you riding with an incorrect map? Pro is for temporary changes - I can't see a scenario where you would intentionally bump the fuel levels across the entire fuel map and ride like that in the long term.
After watching Both Videos, i picked up the FuelX lite for my Husqvarna Vitpilen 401. I installed a Slip on.. and without proper AFR, it feels Muted... so i Ordered the FuelX Lite, and a DNA Stage 2 airbox Mod. Not ready to Decat the Bike just yet. Want to smooth it out first and see how it performs with the 3 basic mods. Im NOT looking for a Race Bike,.. just a Smoother, Cooler Bike with Better Breathing. Fingers crossed it performs what i hope it will
Hey, I have the same Duke 390 with a decat and a DNA stage 2 Airbox lid mod used together with my Rapidbike Evo Exclusive. Would you recommend to install the Fuel X lite as well for some extra power? I am planning to use a Leovince Slip on too.
The installation was a demonstration only. If I wanted an entry level system then the FuelX Lite would be my choice, otherwise the Evo continues to be my recommendation and choice for the rider who wants to be able to modify their bike then get on and ride.
Hi I commented on one of your previous vids and got the fuel x lite in from a dealer in the Uk got stung with customs here in Ireland but it was still cheaper than getting it off of powertronics website! I’m really exited about installing it but I’m just wondering does the ecu need a rest before/after or is it not necessary cheers
I don't recommend resetting the ECU. Your ECU is currently optimised for your location and riding style - as much as it is able to. The Lite can then just optimise that. If you reset the ECU then it will need to relearn from scratch all the parameters and it will just make the learning period longer.
Does this device make the closed loop on the duke 390 an open loop. I have the powertonic ecu piggyback device already installed on my bike with a paid for custom map and know the bike still has a closed loop to about 60% on the 02 cencor before its open. I did use an o2 censor delete from Power Commander with mixed success. I'm sure a saw a vid saying you could the powertronic ecu and the fuel X together. For maximum results. Can you shed any light onto this.
Difficult question to answer since there are two FuelX products - the Lite certainly does not make it open loop because it is autotune, and both connect to the O2 sensor, so it would make no sense for them to make it closed loop. Pro may make it open loop because it is just bumping the maps - but still it's likely closed. Do they work together - yes, Race Dynamics are quite clear that the two products can be used together but they would achieve different objectives.
Hey David, Great explanation as always! Just a quick question. In the wiring harness of my FuelX Lite there also is a earth wire (it’s a 5-pin connector). I wanted to ask you, where should I connect the earth wire of the FuelX harness? Is it ok if I connect it together with the coil’s earth wire? (I know it’s sound like a dumb question, I just want to make sure I don’t screw anything up 😅) Thank you so much! ✌️❤
Would appear the later units/install. instructions do not cater the earth wire, which came with my recent lite unit/install. instructions. Said to fit earth wire to negative battery terminal, albeit both times I've disconnected this terminal bike has thrown ECL which doesn't extinguish until 3 x cold/hot cycles are completed.
@@duncanmillar277 Some units do, some don't it appears. I can't see why it would need to earth to the battery, it's probably just convenient for the install - anything with a good earth to the main frame should be fine.
Looking to add the Fuel X Lite and/or the Powertronic piggyback you my Duke 200. I am wondering though if the Fuel X is even needed/worth it if I am going to run the ECU piggyback. Does running the Fuel X add any actual improvement to the ECU piggy back? If so, what? I appreciate any insight you can give.
FuelX is designed to work with the PowerTRONIC unit. If you only fitted one, I would go with the FuelX Lite, not the other way round. The PT unit is a great one, but it relies on having the right map loaded - an incorrect map can damage your engine, and the maps loaded on the unit at the factory are a starting point for your map, they may or may not be appropriate for your build and how and where you ride. Even if you have the perfect map loaded on the PowerTRONIC, the Lite will fine tune the fuelling as environmental conditions change - bear in mind that the PT unit is designed for the race track, not street riding, so the Lite helps to bridge that gap.
It is a separate issue. If you modify your bike then you will risk the bike no longer being compliant - but not all changes will make the bike non compliant. There are too many variables to discuss whether the FuelX will make the bike non compliant - it isn't a simple yes or no question - a change to one bike in country A may have no impact but the same change made in Country B may make it non compliant because Country B has different environmental conditions. But the real question is enforcement - what is the risk that your bike will be checked? If no one ever checks, then what is your risk?
It should also have come with an installation manual. I have seen similar units with a connection to battery earth, otherwise you will need to earth it to the frame.
In regards to the switch you are putting on the handle bars. ( and maybe you mentioned this?) what about just putting switch under the back seat. How often do you change the fuel mix anyway?
You can put the switch wherever you want. Handlebar is useful because it allows you to change whilst doing your test laps on the track. But, since you ask the question, I would have to check - are you sure the Pro is what you want to buy? Did your tuner recommend it?
@@MotoMirius thanks for getting back. I don’t know any of this stuff. I’m 58, have had a triumph speed triple, triumph Daytona 675r and currently a used ktm 990 superduke. Love the torque of those bikes. I think all I need for the back roads and occasional freeway short run is a ktm 390 duke. 50-60 mph on back roads, and passing speed if needed on freeway. Maybe I’ll learn track riding, I don’t know. I’m thinking a 2023 ktm 390 duke, core out the baffle on stock exhaust or get not too pricey slip on. Next do the air breather thing and one of these piggybacks to improve ride quality. Think I would be ok with the stock sprocket set up. The most reliable set up without headaches. Coiner has some things on line, but it’s $550 and $850 with some pipe thing, I guess to eliminate the catalytic converter. I’m thinking I don’t need to change all that to get alittle improvement over the 2023 stock set up.
Ah OK. Pro is a specialist tool for professional tuners (hence the name), it's designed for professional race teams so they can do a hard and fast hack on race day without loading a new map - it is NOT designed for street riding - I see a lot of people fitting this and it makes me cringe. The Lite is the autotune unit for street riders. I'd ride the bike stock first before you even think of making changes. The trouble with a small engine is that a 10% increase in power isn't' really very much in actual powers so a couple of % from small changes isn't very noticeable at all. Bear in mind that the engine isn't designed for pottering around at low revs, you need to use it as you describe for back roads and ring its neck - this is what the engine designers intended. Most of the mods you see are more sound oriented not power. I would suggest debaffle, cat delete (do not delete the ugly black presilencer), airbox lid filter and the lite. A cat delete pipe isn't much money and you will be well under the numbers that you are talking about.@@michaelrieser9928
@@MotoMirius awesome, sound advice. Ride it stock and go from there. You must cringe a lot because so many reviewers and bike enthusiasts think you have to get bigger than 800cc.

Simplier machine to deal with vs a speed triple etc. I will study the rest of your content in depth
Funnily I had just this conversation the other day. Riding a big, fast bike is an exercise in frustration. Speed limits are being reduced, cameras are ever more common and traffic is too heavy - every car you overtake just puts you behind the next one thirty seconds later. There is an old saying - it's more fun and takes more skill to ride a slow bike fast and at it's limits than it is to ride a fast bike slowly @michaelrieser9928
How much does the airfilter thing and endpipe mod plus the xfuel do? Will i get a quicker bike? And how much will i get? How is your experience with the POWAAAH you get?😁
Never put it on a dyno and certainly can't afford to do that for every mod. I'm very happy with the power levels on the bike now - but I'd need to have a go on a stock bike to know if it's really any different.
Hey @Moto Mirius , do you maybe know if there is a european distributor for this product? I wanted to order it, but the taxes and shipping cost more than the actual product and that annoys me a little bit.. Thanks for the videos, they really help me to maintain my bike!
Unfortunately, not that I'm aware of. Price would be higher anyway because the distributor would still get stung for shipping and import, which they would have to pass on to you to some extent.
I've already done the shorty exhaust outta my stock muffler the dealership said it wouldn't void my warranty is it safe for me to run a after market air box lid on my stock ecu or let me know which Application is best for me
No, not recommended to run air box lid, especially if you are running that slip on. What I recommend for street riders who are just looking at a couple of mods is the FuelX Lite.
Hey David, hope you're doing well. I wanted to know, as I am already using powertronic piggyback ecu on my 2018 KTM Duke 390, if I replace that with this fuel x Pro version is there any difference I can get?
This will work with your PowerTRONIC unit. If you use the Lite it will correct fuelling issues in the map, if you use Pro you can use it to bump the fuel levels in your PT map up and down to compensate for changes you haven't altered the map for, especially useful if those changes are short term like running at a different track or location.
Hey David, Greetings from Jersey Channel Islands! Love your work and attention to detail. Recently upgraded my 125 Duke to a 390 Duke. Just ordered the FuelX lite as bike stalls randomly while on traffic etc. I assume will fix the problem (speed limit in Jersey is 40mph.. got to behave lol). Stay well and keep on "Ready to Race!!"
Thank, nice upgrade. Going to be hard to keep that speed down! Watch the clutch control - just a little bit too much clutch, just a little bit low on the revs and it will stall regardless of fuelling - it's a compromise with a fast revving engine and don't be tempted to change up too soon - the bike loves the revs.
@@MotoMirius yes sir, I have a pro and currently I’m riding on 7 blinks at city and 4 blinks on higher altitude. Well not so higher altitude may be 2400 Meters above sea level.
@@ayushrana7505 The Pro is designed to work with a map so that you can make a one off adjustment - like when you are at higher altitude, so it should work well for your use. But first you need to have a base map for your normal riding. In normal riding, the Pro should be set in the neutral position - because your base map should be tuned for that. If you are riding with just the stock ECU then you need to do some testing to see what the setting you need is - there are a number of factors which drive this - temperature, humidity, altitude etc which means there is no advice I can give you as this will be different for you than for me even if we both had exactly the same bike setup. Be VERY wary of using a setting because someone else thinks it is the best one - this is an easy way to damage your engine, and engine rebuilds are very expensive. I recommend finding a reputable dyno in your area (ideally one used by people who race on the track - not someone who does it over the internet or is used by the street racers) and get them to test for the correct setting.
@@MotoMirius sir, I am riding with dna air filters and on the city I am riding on 5 blinks and if I am riding on 2500 meters altitude above sea level then I’m riding on blink 2.
@@ayushrana7505 Pro is intended for race teams so that they can make a one off change to their tested base map - but this change is made under the hands of a skilled mechanic. It doesn't matter what your setup is - you need to test what is the correct setting for your setup and location - and this can change at different times of year. No one can advise you over the internet what the correct settings are.
Really common problem, and only a small number of those that do are really qualified to do it, and of those not all use the right software. Which is a big reason I use autotune
Appreciate the work you done here for us. You'll not apply the unit cause you have another one and you ripped off the bike only to show us how we do the process :)
Sure is, which is one reason people make poor choice - they listen to friends who are not experts or worse get recommendations from random strangers on Facebook Groups.
Hi , I have a project with my duke 390 , I am buying an adn high flow cap filter ,a k&n high flow filter, I have a full system non catalytic exhaust "akrapovic"(Chinese)😂 and a gray area ktm injector . The question is a Fuel X lite configures all that well? Or do I have to buy a powertronic ECU? I really don't look for final speed, but the as optimal performance and if that gives me more horses is a plus ,but I look for smoothness and responsiveness ,with good performance , I love it but like it lacks something else 💪.
According to the Race Dynamics engineers the Lite will adapt to all levels of change. Getting the right fuelling will help not so much with improving the power but in correcting the things that are currently losing you power. But for actual power improvements you need a full piggyback and spend time on the dyno so the map and build are all optimised.
@@MotoMirius Thank you always, all your video are very good and educational, already told me that the fuel X works but do not install the injector, everything else if. And if I want the injector than install a powertronic or rapid bike evo and take it to dyno. I just wanted to improve its efficiency but not invest so much money. I appreciate your guidance
Yes, my ignition cover is a royal pita to remove too! I use the careful screwdriver pry method like you too...

8:10 - Aprox 2000 lbs of pressure needed, it's a git to get off. I put some rubber grease on mine when it wnt back on to hopefully help next time!

So if I wanna do a slip on exhaust an air box lid what do I need to do to my bike so it runs rite
FuelX Lite
🖤Love from india
Thanks!
Hey @Moto Mirius , do you maybe know if there is a european distributor for this product? I wanted to order it, but the taxes and shipping cost more than the actual product and that annoys me a little bit..
Thanks for the videos, they really help me to maintain my bike!
Unfortunately, not that I'm aware of. Price would be higher anyway because the distributor would still get stung for shipping and import, which they would have to pass on to you to some extent.
To Greece costs 156€ more. (Taxes,shipping). That means almost 300€.
@@George.sam78 finland shipping 155€, while the product is 138€.. hurts :D
@@jls.mp4 unfortunately the shipping is almost the same price. And there is no dealer in Europe.
Hitchcocks motorcycles in Birmingham are the UK distributor. £160.00 for the Lite including P&P and it arrived next day. (June 2023)
I've already done the shorty exhaust outta my stock muffler the dealership said it wouldn't void my warranty is it safe for me to run a after market air box lid on my stock ecu or let me know which Application is best for me
No, not recommended to run air box lid, especially if you are running that slip on. What I recommend for street riders who are just looking at a couple of mods is the FuelX Lite.
Hey David, hope you're doing well.
I wanted to know, as I am already using powertronic piggyback ecu on my 2018 KTM Duke 390, if I replace that with this fuel x Pro version is there any difference I can get?
This will work with your PowerTRONIC unit. If you use the Lite it will correct fuelling issues in the map, if you use Pro you can use it to bump the fuel levels in your PT map up and down to compensate for changes you haven't altered the map for, especially useful if those changes are short term like running at a different track or location.
Why would you ?
You can adjust the mapping in your Powertronic as well. Put it on a dyno, measure the AFR with a quality lambda sonde and adjust.
Hey David,
Greetings from Jersey Channel Islands!
Love your work and attention to detail.
Recently upgraded my 125 Duke to a 390 Duke. Just ordered the FuelX lite as bike stalls randomly while on traffic etc. I assume will fix the problem (speed limit in Jersey is 40mph.. got to behave lol).
Stay well and keep on "Ready to Race!!"
Thank, nice upgrade. Going to be hard to keep that speed down! Watch the clutch control - just a little bit too much clutch, just a little bit low on the revs and it will stall regardless of fuelling - it's a compromise with a fast revving engine and don't be tempted to change up too soon - the bike loves the revs.
I am from Nepal, I have been riding in the city at 7 blinks and 4 blinks at higher altitude. Is this setting fine Sir?
I assume that you have the Pro?
@@MotoMirius yes sir, I have a pro and currently I’m riding on 7 blinks at city and 4 blinks on higher altitude.
Well not so higher altitude may be 2400
Meters above sea level.
@@ayushrana7505 The Pro is designed to work with a map so that you can make a one off adjustment - like when you are at higher altitude, so it should work well for your use.
But first you need to have a base map for your normal riding. In normal riding, the Pro should be set in the neutral position - because your base map should be tuned for that. If you are riding with just the stock ECU then you need to do some testing to see what the setting you need is - there are a number of factors which drive this - temperature, humidity, altitude etc which means there is no advice I can give you as this will be different for you than for me even if we both had exactly the same bike setup. Be VERY wary of using a setting because someone else thinks it is the best one - this is an easy way to damage your engine, and engine rebuilds are very expensive. I recommend finding a reputable dyno in your area (ideally one used by people who race on the track - not someone who does it over the internet or is used by the street racers) and get them to test for the correct setting.
@@MotoMirius sir, I am riding with dna air filters and on the city I am riding on 5 blinks and if I am riding on 2500 meters altitude above sea level then I’m riding on blink 2.
@@ayushrana7505 Pro is intended for race teams so that they can make a one off change to their tested base map - but this change is made under the hands of a skilled mechanic.
It doesn't matter what your setup is - you need to test what is the correct setting for your setup and location - and this can change at different times of year. No one can advise you over the internet what the correct settings are.
No one in my area does dyno tunes or nothing like that on bikes around where I live
Really common problem, and only a small number of those that do are really qualified to do it, and of those not all use the right software. Which is a big reason I use autotune
Appreciate the work you done here for us. You'll not apply the unit cause you have another one and you ripped off the bike only to show us how we do the process :)
Thanks, yes with the EVO, my bike already has this functionality, but who knows what the future will hold!
Ride review please
I already run a full autotune setup which includes all the sensors not just the the Lambda, so I won't be using this anytime soon, unfortunately.
@@MotoMirius Okay Thanks Love from India
There is so much on the market kinda confusing
Sure is, which is one reason people make poor choice - they listen to friends who are not experts or worse get recommendations from random strangers on Facebook Groups.

Hi , I have a project with my duke 390 , I am buying an adn high flow cap filter ,a k&n high flow filter, I have a full system non catalytic exhaust "akrapovic"(Chinese)😂 and a gray area ktm injector . The question is a Fuel X lite configures all that well? Or do I have to buy a powertronic ECU? I really don't look for final speed, but the as optimal performance and if that gives me more horses is a plus ,but I look for smoothness and responsiveness ,with good performance , I love it but like it lacks something else 💪.
According to the Race Dynamics engineers the Lite will adapt to all levels of change. Getting the right fuelling will help not so much with improving the power but in correcting the things that are currently losing you power. But for actual power improvements you need a full piggyback and spend time on the dyno so the map and build are all optimised.
@@MotoMirius Thank you always, all your video are very good and educational, already told me that the fuel X works but do not install the injector, everything else if. And if I want the injector than install a powertronic or rapid bike evo and take it to dyno. I just wanted to improve its efficiency but not invest so much money. I appreciate your guidance
Evo is autotune, so no dyno@@owenrivera6503
@@MotoMirius thank you 💪
