Building the Fastest KTM 250SXF Part 1: Fuel and ECU Tuning

Let's build the fastest KTM 250sxf!
We installed a GET ECU, put 5 days of mapping development and hundreds of dyno pulls, got a base tune, then added VP racing fuels MR pro6 fuel and retuned for max power.
We will post a how to tune your bike video soon.
This is by far the fastest production 250f ever built.... well - that people buy! Our TM250f was even stronger - that's another video for another day...
Follow along as we continue to mod this 22 ktm 250sxf Factory Edition

This 250 already exceeds just about any Race bike money can buy - how much more power do you think we can find in this build series? IN MXA, as it sits, this would be about 50 hp.

[@adamnjethro4080]

So is the pro6 the best vp fuel with mapping for this particular bike and how stable is the fuel as far as shelf life or tank life as a weekend warrior who just like putting gains on his bike slowly lol

[@HPRaceDevelopment]

@@adamnjethro4080 Pro 6 makes the most power of any fuel we have tested on any bike. It's just extremely expensive. If you always reseal you can, and leave it out of the sun, it has a solid 3 month shelf life, we have no issues with it with our clients. But ideally you'd want to burn up your opened can within 1.5 months. It works pretty darn well on stock mapping too - still good gains. BUt of course our ecu and this fuel is extra nice.

[@adamnjethro4080]

@@HPRaceDevelopment I’ll have to try it right now I’m running the t4 just got the bike trying to put a list of possible ideas I’d like to do and this is definitely one I’d just like to see the thing built as possible lol

[@jasonolmsted4147]

Could I use the vp pro6 in a ktm 125 mix in my oil with it and pick up a lot of power?

[@HPRaceDevelopment]

@@jasonolmsted4147 I would choose a higher octane fuel, such as MRX02.

Will the athena ecu for 2022 250 sx f Bacis model fit the 2022.5 factory edition still? As you know it’s a pain in the ass getting after market parts for 2022.5 factory editions and I just wanted to make sure it worked on the 2022.5 factory edition because I’m not able to find it for the 2022.5 250 sx f factory edition only the regular 2022 ktm sx f

[@HPRaceDevelopment]

if purchased from us it will, we have the only get map for 22.5 available. however it wont work well if you use a 22 model on a 22.5

[@charlesclapper8982]

I can't find on web site can u gibe me part number

[@mikeolson7188]

New sub here,have you guys tried the VP 4.4 With your Vortex ECM and how much more h.p. over stock would that fuel generate.

[@HPRaceDevelopment]

This isnt a vortex ecu - GET. and every fuel requires its own proper tune up. 4.4 isnt our favorite fuel but it can make about 1 hp properly tuned vs pump gas

[@HPRaceDevelopment]

@@mikeolson7188 We don't run vortex ecus. Only when a client supplies one do we use them. Yes I have run 4.4 with our mapping. I don't feel it's the correct fuel for people to buy, it burns very dirty and doesn't add the amount of power per dollar that I feel is worth the money. Might as well run pump gas

[@piasiniengineering]

The more option that aftermarket ecu GET offer it's great, but for most user the reflash of the stock ecu will be a better choice, torque and power results will be same, but at lower cost.

[@HPRaceDevelopment]

You can not reflash stock ktm ecus any year after 2020, ktm locked them out of their software (which we own). The oem reflashing is extremely limited in access on previous years as well. What makes a bike run good on track is much much different than simple ignition and fuel changes.

[@piasiniengineering]

@@HPRaceDevelopment I'm not talking about setting the E2prom with the K User Setting Tool, this allows few setups under limitation of factory. what I'm talking is the reflash the entire ROM and e2prom, even to clone the ecu from a 250 over a 450 ;-) maybe you did not know that we only have the solution, but it is possible. i will post soon a full movie of the entire process on the dyno, then you can take your opinion. i agree with you that with the reflash can't get +25hp, but for sure can setting as need for different changes done over the engine. #Piasiniengineering

[@HPRaceDevelopment]

@@piasiniengineering Im not going to waste my time hacking an oem ecu - just not enough market for it

[@piasiniengineering]

@@HPRaceDevelopment Calibrate the ecu is never waste time, also you show here that you done 100 puls on dyno and hours of work, that confirms changing the stock ecu to GET aftermarket can gain about few hp. We have already the solution to flash the stock one, we develop it and no one else have the solution currently worldwide. The 100 emails we got from any part of the world to tune the stock ecu, don't seam to confirm what you claim. My intent was only to let you know that it's possible to do the reflash of OEM ecu. I'm sorry if you take my info as insinuation. I follow your channel from a lot of time, always precise and professional, but please do the same to us too, we are in the reflash field from 25 years

[@HPRaceDevelopment]

@@piasiniengineering we can’t sell enough reflashes of stock ecus’ at a rate high enough to justify the investment of time. Additionally our data logging system that integrates with teh get allows us on track data, that allows for much better real work tuning than on dyno tuning only. I can not integrate this easily on the OEM ecu either.

[@rickejosh1]

Is there a mapping that is designed to create more power with pump gas?

[@HPRaceDevelopment]

dyno chart shown in the video - our ECU with pump gas tune is 1 hp better bottom to top with better throttle response and recovery

[@adamnjethro4080]

I know I’m always asking questions but is there big differences in different manufacturers exhaust fmf vs akraprovic for this exact bike I think fmf is the only one with the header and pipe so I guess it’s kinda easy to guess the fmf would be better but assuming both were full systems what’s the difference in them? Sorry if I wrote that horribly haha

[@HPRaceDevelopment]

They all run very similarly - without a custom ecu tune for each exhaust you will mostly be feeling tune change differences not power differences.

[@adamnjethro4080]

@@HPRaceDevelopment thank you I guess I’d go with the fmf cool company anyway can I ask you the difference between a get and vortex ecu just very confusing looking at all this stuff hahaha thank you again

[@HPRaceDevelopment]

@@adamnjethro4080 vortex somehow markets better despite not marketing. Get has better technology and has innovate the majority of cool things in the industry - such as dual injection - get first, smart phone wifi tuning (yamaha) get had first. Both can run about the same if tuned by the same person. GET works with OEM's - and get is on more pro winning teams and bikes. But vortex is with better marketting companies and argueably more shops resell vortex.

[@adamnjethro4080]

@@HPRaceDevelopment thank you you are the man so if I grab a get ecu would I be able to wire the stock oem map switch to it? If I want to get stuff off you in the future do you need to dyno my bike or do u use the same info from this bike I’m new to all this sorry if I’m bothersome haha

@@adamnjethro4080 Not currently using OEM map switch, but in the future maybe. under discussion at GET. we sell a brand called carrot that used OEM ecu, excellent ecu but more pricey

Let us hear the engine not the repetitive music - also hard to hear you talk over music

[@HPRaceDevelopment]

At the time of shooting - microphone blows out during dyno runs - if you want your eardrums blown out - I'll gladly upload that for you and you can forever never hear music again... When I listen here - music well below volume of talking???? Dunno. Same with iphone, pc, tv and headphones.
