    Great video man! You never fail to entertain. Personally, Carburators are my way to go. I can tune it how I want whenever I want and its always perfect. If you mastered the art of carb tuning, (Assuming nothing else it wrong) you can get any machine to never skip a beat.
    Sure the convenience and realiability of EFI is much better however, it is just an enjoyable experience seeing a machine go from running mediocre to running perfect. It takes away from why i love the hobby so much.

    Another great video. Thank you. I would agree as I run a 15 300EXC with a Lectron and a 23 300SX TBI. Both with high compression heads and the 300SXS CDI in the 15 bike, so pretty similar characters.
    What the TBI does great is mostly on the PV control, you can have the best of both worlds. It’s also better on the top end than the fixed power jet on the 38HV Lectron. They’re both crisp to ride and both similar on fuel. The TBI edges it a little.
    The 23 300SX TBI is bang on out the box, I put 35hrs on mine before messing with it. Went with the TSP power kit but found your videos looking for tuning info.
    Their kit with the head and ERM is good, the MX4 map is crisp, the white map is better (stock one is a bit limp) but I liked the bottom on the stock green map better for the dunes. Their green map will be better at our local 🇦🇪 MX track which is hot dusty hardpack like theirs in Oz. 🇦🇺
    Clever stuff all this… for all the clever advancements in four stroke technology… they’ve never made them as fun or interesting as two strokes. 🤭
    Keep up the good work and thanks for sharing great content. 😎

    I remember when Honda tried using EFi on their 500 Gp road race twostrokes. some friends of mine were on the team and their take on EFi two stokes was in the end to leave the carby on them. There were no performance gains to be had in the end. It could be a tool to get past some emissions or fuel consumption requirements that we don't have in MX but as far as performance and Moto go I believe it makes the bike more expensive to own and operate. The lifecycle of the Bike will be reduced and the resale value drop to zero in 5 or 6 years. The increased purchase prices efi brings plus the running cost and lack of cheap used bikes that entry-level riders usually start with will make this sport smaller in the future. Factory management is pushing for quick profit increases but the long-term effect will be a smaller sport,

    Crazy that the technology was released like this. We bought a very early 2023 TC250 in late 2022. We just came off a 2019TC250 carburetor machine. The 2023 gained weight and made less seat of the pants power. Tried to live with it, but just couldn’t. We were nailing hole shots on the 2019 in the 250 class and the 2023 couldn’t even pull away from a 250 4 stroke. Not competitive at all. Dealer was confident it was running right. Sold it back to them with less than 10 hours on it. Was super bummed. Wish we would have waited to buy that bike until they worked out the bugs or guys like you had these aftermarket ECUs developed.

    • @HPRaceDevelopment

      Consumers "said they wanted it" enough that they spent millions to try and sell it. Im not sure it will ever surpass a good carb - but 2 strokes are really and truly about dead for mx. Offroad wise these are just fine and the vast majority of KTM groups customers.

      @@HPRaceDevelopment I get it. It would be outstanding if the racers had a way to petition the AMA to allow a straight 250 class in pro racing (similar to Canada and Australia IIRC) I think most up and coming racers jump to the 250f because they know that ultimately, if they want a chance in the pro ranks, the 250f is the only choice….even though only 40 guys get to line up on a pro MX gate each weekend. We are racing for fun, so we’ll take the light weight, simple rebuilds, and increased HP of the two stroke, just not the TBI one until the bugs are worked out ;)

    • @HPRaceDevelopment
      @HPRaceDevelopment  ปีที่แล้ว +1

      I think at the pro level people would be sorely dissapointed to see just how fast the 250fs are. Our Pro Bikes aren't quite where the factory ones are (working every day to close that gap) but I'd take our pro level 250f over our best 250 2t's any day on 90 percent of the tracks. Pure sand, or super smooth fast tracks, 250 2t all day baby! I think the TBI will be mostly fine, part of the issue is the "consumer" in many ways. People ride bikes in goofy ways that engineers struggle to comprehend. For example our supercross yz250 we put a rev limiter at 11500 RPM. I figured he would only rarely hit it - and it helped us in sound testing and reliability. NOPE! he hit it all the time. The bike makes like 10 hp at 12k - but he hits it constantly and hated it....@@86rustbucket

They don't always mean the bike doesn't run but its pretty annoying to see the on the starting line. Will this GET ECU have a way that we could look at and clear these codes? This would help us and our customers greatly. Now the options are to clear are take to KTM dealer or the KTM support tent which can be a real pain. Thank you

    I wish the few manufacturers that still make 2-strokes would have just stuck with carburetors or went all the way to direct injection like E-TEC system on Skidoo-snowmobiles….this seems like a step backwards on multiple forefronts…..even upgrading 2-stroke dirt bikes to 90’s moto-GP tech would have been welcomed / appreciated (power jet with variable timing based on TPS and set-counter that adjusts timing maps on the fly), which wouldn’t be as hard to do now, as it was back then.

    Thanks for the great and informative video. We have long suspected that there is a difference in power between bikes, first time i see dyno numbers on it
    Now GET boxes have started to appear at dealers here in Sweden, I will test it on my son's 125. I wonder how it works with error codes, are they stored in the GET box. Can I read out and reset codes myself? and what happens to the hourmeter when you change the box? Thanks

    • @HPRaceDevelopment
      @HPRaceDevelopment  ปีที่แล้ว +1

      I hadn't even thought about the hour meter - it likely doesn't work correctly if the bike already had hours because the GET internal hour meter wont have any hours yet. The std GET maps run pretty well on the dyno, but we had track issues that we think we have mostly resolved. EFI will be a very long ongoing challenge! Once the wifi comms are avialable you can read sensors live and read and faults it detects. We might have our own wifi comm soon - testing shortly

    • @HPRaceDevelopment
      @HPRaceDevelopment  7 หลายเดือนก่อน

      Dirtbikes dont trim like a car. There is no sensor that returns lamda or combustion data to the ecu. The only correction factors off measurement are baro and map sensor and intake air temp, as well as coolant temp. The ecu reads these as its running and adjusts according to its programmed settings to do so.
      The bike shown here resides here and is ridden here full time… It was just a dud.

    Derek have you had any austrian TBI 2 strokes that require throttle to start when warm? Ever since day 1 with my brand new 250 XC-W it requires ZERO throttle to start when the bike is stone cold, but when it's warmed up it always requires a C-hair of throttle to start. Otherwise the starter will just spin and spin. I always see guys starting their bikes with a split second push of the button. After a TSP medium comp head install and ECU flash it's still the same. Not a big deal, but I was just curious. Funny how some of the TBI bikes you see run great and others run like 💩.

    You can't do tests on a cold bike. Those bikes must be 165° minimum before they can be ran properly. The computer in the bike adjust according to the temperature. You first start those bikes and start grabbing that throttle you're injecting too much oil into the engine and foulingi the plug. When an engine is cold the bike is being fed extra oil to protect the motor. When it is warmed up it receives less oil. In other words you're drowning the bike. Then trying to say that ECU is better than the stock one. Simply put a temperature gauge on all your bikes get them up to a 165° then do your tests. You will see a massive difference
