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 😅

[@MotoMirius]

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]

​@@MotoMiriushello, what else would you recommend doing to help at low revs then? Maybe a different sprocket?

[@MotoMirius]

@@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.

[@ntdeas]

@@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.

[@steven-vn9ui]

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!

[@MotoMirius]

Sad to say rubber grease doesn't make a significant improvement. But a flat blade screwdriver across the ignition switch applying gentle lift while ripping holes in your fingertips does the job nicely.

[@TheBigBlueMarble]

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).

[@MotoMirius]

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.

[@dantediss1]

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

[@MotoMirius]

Nice. DNA airbox lid actually counts as a major mod so you are well into piggyback territory. Lite should work well.

[@yan6520]

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.

[@MotoMirius]

You won't be able to fit the Fuelx with the EVO, nor is there any reason to.

[@danielzito93]

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! ✌️❤

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!!"

[@MotoMirius]

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.

[@tanzsj]

where do you get the tank sticker to cover the shiny finish? its so annoying to keep it scratch free

[@toxicgamingsnipz1216]

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

[@MotoMirius]

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.

[@toxicgamingsnipz1216]

That’s lovely thanks again for quick reply

[@JonPLTNM]

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.

[@MotoMirius]

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.

[@michaelrieser9928]

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?

[@MotoMirius]

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?

[@michaelrieser9928]

@@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.

[@MotoMirius]

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

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.

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.

[@blackeagle7765]

After installing fuelx lite Does this create a problem while checking pollution of our bike ? No one has talked about this

[@MotoMirius]

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?

[@RupeWilson]

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.

[@MotoMirius]

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.

[@IamRayzor1995]

Do you think the Lite would be able to handle an open airbox lid? Or would that require a more substantial piggyback?

According to the Race Dynamics engineers, it will handle all modifications not just an airbox lid

[@MotoMirius]

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.

@@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.

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.
