![MUST-DO MOD for the NEW TBI BIKES [TSP ERM Review on 2024 TE300]](/img/1.gif)
I tell everyone " I told you so" hahaha love my tsp kit!
I just received my TSP ERM and med. comp. Head today for my 23 TE300 and super stoked to put it on!!!
Put the med comp kit on my '21 te300i and fell in love with my bike all over again.
The low RPM lug seems unstoppable.
I'm very impressed at how well it lugs at low rpm, without stalling.
Great first impressions video. Similar finding here as well for a dedicated 300SX snowbike build using the TSP MX Tune.
Great review, bike lugs like a tractor now 👌
Nice!
Didn't skip a beat!
wow!! i would have it. anyway, it looks very similar to the mountains and courses in Korea here.
I just put same kit on my 24, anxious to get some seat time.
I'm sure you'll love it...
Great video - thanks for sharing. Did you notice any noticeable difference in the 'snappiness'? I.e. did it become easier to lift the front wheel after these changes?
It's snappy enough for me (can easily raise the front wheel). The ground was pretty frozen on the Sunday ride so difficult to fully test. I'll post further videos as I gain more ride time with it, but liking it so far...
Thank you for all the very good stuff you share!! I'm looking to get that bike and consider to buy the TSP kit too. What's the maps you ordered with the kit for the green and white option?
With the ERM power kit, you download the map after purchase. I download the latest map offered by TSP: 3BE-24-1, released on Jan 22 Jan 2024.
@@TokyoOffroad Ok, I saw somewhere you can choose a map more oriented technical stuff or more open single track? Is it still the case or they changed that?
@@matlafalange1 The TSP map, just like the stock KTM map, has green (regular power) and white (richer, lower power for slick conditions) choices. I haven't tested the TSP white map yet. Will do though...
Forgot to ask, have you tried the TSP new map with the stock head to see the difference with the medium comp TSP head? I saw in another of your videos that the compression is very similar. I’m looking to buy the TSP kit but the head is 400+ $ CAD. It’s very expensive for just a head when S3 are half the price. I’m wondering if i really need the TSP head or just the ERM will be good.
Question for you...did you happen to try the bike with only the ECU re-flash to see if that alone was a huge improvement? The thought being that maybe you wouldn't really need the higher compression cap/insert.
No, I installed the TSP medium comp head at the same time. For sure the low end burble (due to over richness) would have been solved by only changing to the TSP map. But the stock head insert design really isn't that great (squish band design is very slack). If you do want to try the TSP head, you have two choices: Purchase the full head (which has slightly improved cooling compared to the stock head cap), or purchase only the TSP head insert which is the same as in the full head kit, but use the KTM stock head cap. I'm still very happy with mine. Smooth and linear power. I just got a TSP PV cover (larger volume than stock) which increase bottom and mid power slightly. I'll make a video about it...
Do you think an ERM updated map can tune out some of the stutter that is present when cruising or just cracking the throttle not under load on my 2024 EXC 300? TPS is spot on.
Yes, with ERM it's easy to make fueling adjustments and then test to see how it feels. If it's a rich stutter try leaning out the setting at low rpm and test it...
Do you find it much easier to run a gear higher over stock form?
Because it lugs so well it is easy to run a higher gear. Traction is so much better when lugging...
Your videos are great! I’ll definitely be getting the kit soon. What gear were you in for all the slow stuff?
Slow stuff was either 2nd, or 1st. My gearing is 13/50 on the 2024. I use 12/50 on my 2017.
@@TokyoOffroad I have a 2017 TE300 and love it. I am, however, intrigued by the TBI motor and am considering investing the money in a new 2024 model. Since it sounds like you have a 2017 and now a 2024… how would you compare the engine power? (How snappy, how much can you lug, etc?)
@moto6193 I'm not exactly sure how tokyo feels on this topic but I believe a well tuned 2017 would be comparable to the low end lug of a TSP equipped TBI. I have a 2023 TX300 and am thinking of equipping the TSP gear to gain more low end torque. The TBI is very smooth and more of a "modern" feel vs the 2017. (I believe the stock TBI has less torque than a 2017 well tuned carb) The new forks on the 2024 TX are awesome. (I upgraded to the 6500 kit on my 23)
@@KaneSlayer414i have the med tsp head and tune now and it made my xcw an absolute monster but tameable monster in the slow nasty stuff. Goat is the word that comes to mind lol
Did you find you needed to alter the idle setting of 0.61V after the tsp map instal?
No, I didn't need to adjust the throttle position sensor voltage. It was already set to 0.4V with the butterfly fully closed (red adjuster fully wound out).
@@TokyoOffroad I meant did you need to alter your idle at all after the tsp map was installed?
@@davidrenfrew1442 I see. Yes, I did tweak the idle setting during the initial part of the ride. I’ll check what voltage I’m at now when I have a chance and reply again…
I just checked and the TPS idle voltage is still set at 0.61V. I did fiddle with it during the ride (up and down) but settled on an idle the same as before.
@@TokyoOffroad curious what voltage is at when your choke is engaged?
Kind of surprised to hear it was rich from the factory seeing as the FI on KTM 2 strokes was motivated by euro emission regulations. I suppose the carb bikes were always rich from the factory as well.
The bike ships from the factory with a super restricted low emissions map, restricted airbox and pipe. To run properly all this needs to be changed (install the competition map, regular pipe and remove airbox restriction). The competition map on the TBI seems to be over rich (from my experience)...
They definitely were not. Typically they came with a heavily restricted pipe and smaller jets etc. so you could theoretically start the bike without immediately drowning the engine. They were never meant to run in this configuration. They would run absolutely terribly and overheat. It was done to pass regulations. Presumably emission regulations, but consequently it also offered flexibility what came to registration and license classes (A1, A2, A).
If you have lived in a country where it hasn't been possible to register 2-strokes anyway then it could be this is something you haven't had to deal with. It is possible that the manufacturers shipped the bikes without any kind of restrictions to begin with or the dealerships simply removed them before selling the bikes to the customers. After all it used to be as simple as switching the pipe to "unrestricted closed-course pipe" (came with the bike) and then rejetting and adjusting the carburetor.
To give you an idea how badly the carb models ran right out of the box, so to speak, imagine KTM EXC 125 that has been restricted so heavily that it makes something like 6 kW... just to pass the emission regulations of road vehicles. 😄
Are u running a high compression head?
No, medium comp head. I made a head install video which includes compression testing of the stock and TSP heads here: ruclips.net/video/cx4NBqgyarM/видео.htmlsi=-zrss-Vb7IUdXBmo
What map did you install?
I'm using TSP map for 2024 KTM 300 EXC/XC-W. I have not changed anything from the baseline setting. The majority of the time I use the green map (higher power).
Can you tell us what your final gearing is currently?
I'm using 13/50 gearing
That's a huge difference from 13/45 stock. I was thinking of throwing a 12 on the front and see how it behaves. Your thoughts? Mathematically their pretty close.
@@TokyoOffroad
Now that you have some more time, still feel the same? I pick um my Husky TE300 this week. I'm coming from a TBI TX300. So, I know.the power is going to feel...meh in comparison.
Yes, with the TSP ERM kit power is very good and works great for the mountain technical riding I do. Super linear so is easy to control. I wasn’t happy with the stock KTM map, particularly small partial throttle riding felt too rich and blubbery. Big improvement in fuel economy with the TSP map. Using the ERM you can adjust the fuel, ignition and PV settings if you’re not happy with the baseline TSP map. Can also read and reset ECU codes and monitor various data. Highly recommend the TSP ERM, although it’s not cheap.
@@TokyoOffroad thank you for the response! Have you messed with the gearing? We ride everything from flowy single to really tight technical stuff, Creek beds, rock gardens. Etc. I was thinking of dropping the front.sprocket down a tooth or going up a few in the rear. I guess we shall see after my first ride. Thanks again for the response!
@@charlesgutscher1923 I'm using 13/50 gearing. Stock my bike came with 13 & 14 front sprockets and 45 rear. If you want to stay with the stock 45 rear sprocket then I'd recommend 12/45.
Why can't they get it this way from the factory?
Not sure...
@@TokyoOffroad emissions and regulatory BS is at the root of it. Look at the XC mapping. Closed course bike and the tune is insane. This is all very theoretical and there is no proof behind it. Makes sense in my mind though.
🇦🇺
Yes, TSP is an Australian company.
Sounds like a tractor…an angry tractor.
Gear down bro
When the ground is frozen lugging at low rpm is great for traction. High rpm lower gear not so much...
@@TokyoOffroad yeah but he is in like 3rd gear there … he is almost stalling the bike … he could gear down and still run a low rpm
@@Jaymayan07 All the riding shown in the video was 1st, or 2nd gear. The GoPro was in Superview which makes the hills look flat. I was impressed with how well the bike lugs (without stalling) and maintains traction in slippery conditions like this, which is why I included it in the footage. On a 300 lugging at low rpm makes slow steep technical riding much easier and less tiring. Obviously if you're riding the bike on faster flowing terrain you're not going to ride the bike like this...
