What a great video. Thank you for explaining the traction control mode.
Great video, interesting how small the difference is on the dyno compared to how much difference it feels on the track👍
Good video, good testing and good info!
Watched this video like 3 times. Can't wait for some new content!
Working on it! lots to come - gotta learn to edit better
@@HPRaceDevelopment Good news, yeah editing and all that is alot of work!
Nice work amigo. Keep these coming
This guys no bullshit spittin facts
Great video! Thank you for testing! Subscribed!
test with 350 pls, and test with backfire screenless air filter skeleton
What a great video tho!
great vid very clear and concise!
Great video.👍
Sick video ty
The thing about the traction control is false information. How could you possible test the tc on the dyno without wheelslip?
The ktm tc is messuring against a set value in the ecu about how fast the engine can ramp up rpm and still have traction. In a low traction condition the wheel(and engine) is able to speed up quicker then this set value, and the ecu retards the timing to regain the set ramp up rpm speed, to regain traction.
We happen to know what's actually the OEM strategy through some relationships we have at GET and other electronic providers, combined with our data acquisition system (I will have a video published on this system eventually) that measures all ECU outputs, inputs etc. If the bike adjusted ignition based on say rate of rpm change - the data box would pick this up, and test strategies are easy. We CAN create tire slip on the dyno easily. The only way to control power on these engine is fuel or ignition - as the throttle body is controlled by the cable - not a servo like cars or sportbikes. OEM bikes also don't have gps or wheel speed sensors for more advanced techniques, which GET does have and use for their high end strategies.
On OEM ecu's It's gear specific mapping, and pulls about 4 degrees out in first, 3 degrees in second, 1 degree in third and std timing in fourth and fifth. That's just thereality of what's going on you don't have like it but is what it is on those generation bikes. The entire reason stock bikes come with "TC" is so the factory teams can legally run it, as the rule books were rewritten to say "if it comes stock it's allowed". The sad reality was traction control has existed for a really long time with the factory teams going back to honda somewhere in the mid 90's but the sanctioning bodies have no way of measuring this or catching them - so rules were re written to save face for ama and allow factories to keep on keeping one without them protesting one another for what they themselves were doing. GET has patented the technology that would have to be licensed by the OEMS to use for "smart strategies based on gear selection, rpm, rate of rpm change, throttle input, rate of throttle input change". which is still a mediocre way to do TC vs what sportbikes and road racing bikes, cars, etc employ. Carrot and GET ecu's are using an on board accelerometer as well to help with their TC strats. OEM is currently NOT using that etither.
Fanboys are now crying over the true facts.
Hi Derek, have you observed the same phenomenon on the 450s? I have a FS450, and running TC on really helps smooth out initial throttle tip in on both map 1 &2 , wondering how it influences power. I’ll probably run it on either way
you can equate tc to an even slower map on both maps
on the 23 ktm, they have done a few bew things which has some dynamic control to input. on older bikes, 22 and previous its just a gear specific power reduction via reduced timing for each gear with 1st having most reduction and 5th none/least
When is the FMF full exhaust on a KTM 250 coming out?
Could you let me know what fuel you ran for these tests? Mainly interested in all stock vs. all stock w/ just GET.
Thank you. VERY clear and informative!
all stock vs all stock with a GET using our maps is what is tested in video. pump gas all runs
@@HPRaceDevelopment thank you!
Have you ever tried to run 89 gas? I know Brock’s does that on street bikes and it makes more power.
In most MX bikes it will do worse
@@HPRaceDevelopment thank you! Love your vids
Can you do a 300xc/w tpi test, with all your mods? Thats the most popular bike and I’m sure alot of people want to see it.
Weve done lots already but I didnt video it - we can go over the charts I have but I think people would want to see the bike on the dyno too
Have you tested the full Acropovic ‘Evolution’ line exhaust?
we have
And what are the results meaning did you get better results than what stock or the slip on gives?
@@cantgetright3657 Exhausts don't add much power these days, they mostly change power feel.
Right but I’m trying to know if the full exhaust gives anymore power/gains than a slip on, if any power at all. I’m guessing based on you’re response it’s a no on the full Acrapovic full Evolution exhaust
@@cantgetright3657 Our goal with these is to educate the consumer (you) on how to think about things. What makes you think that ktm isn't capable of making an exhaust the exact same as any aftermarket pipe as far as design goes (not the look)? These OEMs make COMPLETE dirtbikes - they can certainly make a pipe. So we have to ask ourselves - what are our goals with pipes....to just get more power everywhere is extremely rare now days.
Does removing the spark arrestor give more power
generally nope
Got new triumph it doesnt seem to have 47 hp do u have any maps for thus yet i did 49 rear tooth
Stock ECU is locked
@HPRaceDevelopment
Do they make better one
Like a get ecu
@@charlesclapper8982 I believe there will be - stock is a GET but it's locked. We have a big bore that would fit it
Where do I get
Do the same test on sxf 450
we did
Does a header do more than a slip on?
On the KTM it's been our findings that the OEM exhaust is basically impossible to beat
@@HPRaceDevelopment I have a Husqvarna fc250 and I’m debating if it’s worth it to get an akrapovic exhaust. Better to save the coin. Thank you
I’ve known intuitively that most of the after market stuff was all bullshit like these guys don’t spend millions in r&d and manufacturing and testing to come out with a bike that isn’t going to be as good as it can be in a overall quality and reliability.
while id say what we offer isnt bullshit, i will say its very hard to get large gains off one thing, and the total room for improvement is getting smaller and smaller
the reality is most people want bling not performance
Why doesnt KTM explain these things in detail?
