FuelX Install and Review (KTM 390 Adventure)

[@dCryptid]

Installing this, dna filter, and slip on exhaust now on 2023. Thank you for vid. Love these bikes for lightweight adv.

[@LCARSADV]

Yeah it's just a fun bike. I would like to do an exhaust as well, maybe eliminate that huge CAT

[@dCryptid]

@LCARSADV definitely runs alot smoother in low rpms and responsive. Huge difference with that and DNA filter. I didn't fo the dna airbox cus to dusty where I ride but I'm very happy I ride it hard like a dirtbike so very pleased. I had to wait untill today to install slip on cus I did not order the new mid pipe. I thought about doing the delete also and running a full dominator exhaust. I'm going to see how she does with this and maybe a 14t sprocket first. But it's crushing klr and drz650s out here.

@@dCryptid How have you found it after a few more months?

[@geeksonbikes]

Great video! I've been wondering about the fuelx lite for my 390. Your video helped me pull the trigger so I ordered one today! Thanks again, Live Long and Prosper.

[@LCARSADV]

lol you'll definitely like it. What did you think of SNW's? I don't like new trek at all, but SNW they actually did a decent job

[@geeksonbikes]

@@LCARSADV SNW is by far the best of the new series. I'm however Star Trek hungry so I find something to like in all of them (and ignore what I don't). How about Picard though? Did you like that?

[@LCARSADV]

@@geeksonbikes no I hated Picard and what they did to him and seven. Discovery is just awful. It’s just so different than roddenbarrys vision of a positive humanity

[@geeksonbikes]

@@LCARSADV Yeah Discovery took a very unfortunate turn for the worst... Picard wasn't as bad for me but it also had a little too dark a vibe.... But hey we still have Strange New Worlds LOL

[@zombiewoof5257]

Excellent install/review, short and to the point. Going to install my FuelX lite on of these days, and I think it's easier just to lift the entire fuel tank (breather tubes on front of fuel tank have to be disconnected for that), for easy of access to the connectorts and to route the wires.

[@LCARSADV]

You’re probably right lol, I think fuelx is definitely worth it imo

[@leeedwards7721]

MooreMafia [US Bike Tuner] Says the TPI SHUTS OFF FUEL when you roll off throttle, When he Tunes a bike he takes that away [In the ECU Tune] So when you then Roll off the Engine still gets a little fuel making Removing the Jerking of either ON OR OFF [Like a switch].

[@brizi2003]

I recently fitted a FuelX Lite to my KTM 390 Duke and it didn't have a separate earth connector like yours? (Strange). I didn't notice that much difference with a stock pipe although it did make riding at low revs easier (less jerky), however, after fitting an end can (Ixil Extrem RB) it is now much better at low revs. Making riding below 4000 revs actually possible! Interestingly, it did seem to take some time to bed in and I think this is maybe due to gradual adjustment by the ECU as the FuelX Lite basically just reports a lower air fuel ratio to the ECU to fool it into richening up the mixture. I contacted the supplier and they said the FuelX Lite made no difference at higher revs/full throttle as the ECU was then working in open loop. I do think though that the FuelX does 'soften' the sharp throttle response some what - making the bike easier to control but less agressive and less 'crisp'. I guess the stock fueling runs very close to lean and hence provides very sharp throttle response however, this can feel very jerky at low revs. So I guess it depends on what you want.

[@LCARSADV]

Yeah the fuelx handles all the low stuff and some guys install an additional programmer for the open loop. It pretty much makes the low end useable where as before you need to hit like 6000 rpm for the power to kick in.

[@motojc]

I have contacted the factory they mentioned the open loop close loop thing too (comparing 2 of their products, one works on open, one works on closed). Can you tell me what closed loop and open loop means? thanks.

[@ashishavin8748]

Live long and prosper.

[@MB-gw7os]

Thanks for the video! This made installing the fuel x lite simple

[@LCARSADV]

Your welcome that’s why I made it, glad it helped!

[@gkeller9958]

Thank you for the install clip. I watched some guy from India that partially removed the gas tank and found better access through the coil area. And yes it’s a booger no matter what way get to the connector. I like now that I can idle through a parking lot or slowly ease through a technical trail. Is it worth the price ? Depending on your budget. Not a big dramatic difference, but if like to smooth out the jerkiness at lower rpm it’s one way of doing it. When the sprocket set starts to wear out a bit, I think I’ll go with a 48 tooth in the rear which should help even more. Too bad the manufacturers couldn’t put a mapping switch on at the factory and eliminate this problem just to pass emissions.

[@LCARSADV]

No problem! I'm glad it was helpful. I think the fuex is very much worth it especially for off road where you need those rpm's down low

[@nnlniclb]

get a rapidbike easy or if you have the money an evo and see the true potential of the bike. (I'm exaggerating slightly but the low rpm choppiness is fully gone which I used to think is a character of the 390's) Idk if the fuel X module can affect the closed loop area. It can only increase fuelling for the full rpm cycle I think. which might be bad because you need richer ration in the low rpms without adding even more fuel in the top rpms as the top rpms are usually pretty good as it is. maybe a piggyback with fuelx might be as good as a rapidbike.

[@tomg6284]

I found the pro version to stop the twitchy throttle At low rpm + more grunt.

[@LCARSADV]

Yeah I’m pretty happy with the product. Not a huge difference but enough to justify buying it

[@i_observe9846]

Nice

[@sagnik_datta]

Have you noticed any change in fuel economy?

[@LCARSADV]

Yeah it went down a tiny bit which makes sense since it richens it a little

[@gianniferrari802]

Sulla mia royal hymalaian, non trovo le prese per installare la centralina. Avete un video che mostra come installare FUEL X lite?? Grazie

[@tomfagro6744]

Does this help with the multiple start attempts issue some have?

[@LCARSADV]

I’ve never had an issue starting the 390. Starts right up every time!

[@PNW_Native]

Should this be done when installing an exhaust and intake cover with a K&N filter (the top part, not the stock filter)?

[@motojc]

Thanks for the video. My RC390 is useless below 6K RPM, like I can't let it drop it below 6k. so this one fixes that? And how does it do for MPG?

[@LCARSADV]

Yeah I think it does a good job of making it usable. Mpg dropped 1 or 2 maybe because it runs richer probably

[@motojc]

@@LCARSADV Thanks. I'm doing 55-60mpg. I can afford 1-2mpg drop:)

[@Lemmingadventures]

I have big meat hands too, but I'm not sure I need this. I am happy with my 390, but the only issue I have with it when riding is when I am facing a head wind which we have all the time here in the desert. With the throttle pinned, I can get to 67-69 mph. So it sounds like this would not help me with more power riding into the wind. Am I wrong? Thanks in advance.

[@LCARSADV]

No it doesn’t give more power in the upper end, it smoothes out the low end power. I’m surprised to hear it only goes that fast against the wind, don’t think I’ve ever had that problem.

[@Lemmingadventures]

@@LCARSADV I don't know where you live, but here in Vegas in the open, it's windy all the time.

[@LCARSADV]

I in western NY, but it does get windy going down the highway@@Lemmingadventures

[@JJPsyc]

Hey there. Do you guys know anything about the mysterious bright-green coolant that some of the 390 Adv's are shipping with (that is not the recommended Motorex M3.0 PINK coolant that is in the manual)? I am in the US and picked up my new 2022 390 Adv about 2 weeks ago and it also has the Green coolant. Thanks!

[@LCARSADV]

Mine is green as well. I’m wondering if the dealer is the one who puts the coolant in which would make sense.

[@JJPsyc]

@@LCARSADV I confirmed that it comes from the factory with it. There was a bulletin from Motorex that explicitly states the dangers of using the KTM M5.0 coolant, due to silicate content. Pretty frustrating.

[@motojc]

I've asked my dealer too. They said that is he KTM factory fill up. The dealer has a red stuff, I'm hesitant to mix them...

[@vishaalpamulapati7035]

My adv 390 is 5 months old and ive installed fuelx pro a couple of weeks back and ever since then my battery has taken a hit and it hasnt been starting now. Do you think fuelx pro has anything to do with that?

[@LCARSADV]

If your battery is discharging then you have a resistive load somewhere, it's possible the FUELx could be doing that if it's defective I guess, but I don't think it receives any power until you turn the key. So that means you might have a frayed wire possibly from the install rubbing against the frame.

[@vishaalpamulapati7035]

@@LCARSADV ok I'll check it out

[@tomg6284]

Thanks for the video. I think my 390 is broken, in a good way. I feel the power is great as long as I hit 4000+. I will grab one to try out though. - Frank

[@LCARSADV]

And that’s where the fuelx comes in, it’s useable power before the 4000 rpm range. This bike and every other bike are just to lean from the factory

[@OneOldManRiding]

@@LCARSADV I am an owner of Yamaha online four bikes, I have become used to going from 0-6K RPMs instantly. 🤣 Before 4K my FZ6 refuses to move! - Frank

[@nnlniclb]

@@LCARSADV the rapidbike is the best if you can get it as it can affect just the low rpm if you buy rapidbike easy or autotune perfectly for every rpm if you get rapidbike evo. Problem with fuelX is it increases fuelling with the full range. So when you bring 0-4000 rpm range to a good AFR, the 4000+ range will run too rich which makes your engine get gunky and cause buildup and deposits inside. I believe rapidbike is the only option which can truly access and make changes to the closed loop area of the rpm range.

[@faiyazelahi8903]

Hi,does it ever feel to you that you should have gone for the 'Pro' variant? I am going to have a Fuel X Lite for my Xpulse 200 4v but confused between the Lite and the Pro. My usage is 90% in the city and 10% on the highways. I don't do trips like Leh ladakh etc., What would be your suggestion? Lite or Pro?​@@LCARSADV

[@LCARSADV]

@@faiyazelahi8903 I haven’t had the pro, but I went with the lite because it’s all automatic and less fussing.

[@MrTanagax]

I have a cat delete system and i backfire a lot as well jerkiness in 6k rpm and up, some kind of loss of torque since im using stock ecu. Will this help me even having stock filter my bike is rc 390 22

[@LCARSADV]

I think this fuelx only takes care of low end stuff, you’d need a fuel programmer to take care of higher throttle stuff. I forget who makes it, but others have it. Mine isn’t jerky at 6k but you deleted the cat so maybe that’s why

[@MrTanagax]

@@LCARSADV having hard time finding a person who could reflash cat was delete and change to a resonator, stock ecu is locked they were unable to unlock it for reflashing or tuning.

[@LCARSADV]

Yeah there was, but it’s not in depth on what to remove and what not. Just wire placement

[@Bisse_Elison]

@@LCARSADV ok. That is not optimal. Hope they fix that.

[@bhishankhatiwoda7537]

can you pls try on how low can a bike run on 6th gear after installing this...if low end torque has increased then, it should be definitely worth it !!

[@LCARSADV]

I wouldn’t say it actually increases torque but rather it makes it useable in the lower rpm which allows you to lug around in higher gears

[@bhishankhatiwoda7537]

@@LCARSADV yes i am saying on layman terms ´increase in torque´ which isn't the case actually🤣.. anyways, i would like to see ur feedback on how low can a speed be maintained on 6 th gear please !

[@gkeller9958]

@@bhishankhatiwoda7537 I’ll run 3000 rpm’s in 6th gear on level ground without loosing speed and still pull out the rpm’s without it lugging to where I need to down shift. That being said, it won’t pull the hills at that rpm in 6th gear. I do feel that I’m shifting less because I can pull the rpm’s lower. On the other hand when you hit the 6000 to 8000 rpm you don’t get that wow factor like with stock. Now, it’s still there but a bit smoother. I bought the X factor for more useable rpm’s on the trails. I can now idle in first gear without it jerking me around. Before, anything below 4000 rpm’s was unusable. Hope this helps

[@orange42]

Funny the things you mention are all identical to the new Triumph 400 stories. So would undoubtedly solve them too.

[@LCARSADV]

All in all I do like it, it doesn’t seem placebo anyways

[@kenjisan7970]

Have you tried it off-road yet? I’m mainly interested in how the Fuel-x helps low speed manoeuvres and low rpm operation.

[@LCARSADV]

Yes I have and it does make a difference. Before in stock form the throttle really want usable until you reached 5k rpm and it was kind of jumpy. The fuelx smoothed all that out and makes the engine power more usable down low which for off road is good
