Product Information

2011-2018 KTM & 2014-2018 HUSQVARNA 250 /350/450/500/501 4-STROKE CUSTOM ECU MAPPING SERVICE

This service is for 2011-18 KTM and 2014-2018 Husky Closed Course 4-stroke Fuel Injected MX bikes!  Only works for KTM SXF/XCF and Husqvarna FC/FX Models!  We are able to reduce Flameouts by about 50% normally.  I also recommend our 7 Ounce Clutch weight also.

We can now do the below models if you already have an unlocked ECU with the EURO Map Installed from your dealer.  This is especially important when running a aftermarket exhaust and if you have the Reed Cage Restrictor removed from the airboot.  Even with the EURO map your  2017 KTM/Husqvarna EXC/FE 450/500/501 model bikes will be in the neighborhood of 16:1 AFR which is in the danger zone at 8000 + RPM.  Our setup is also more performance oriented and will be another 10% jump in power over the standard EURO mapping. If you dont know what the EURO map is then you dont have it in your bike and I cannot make any changes to your ECU.

2012-18 KTM 250/350/450/500 EXC/EXC-F Models (Must have EURO map already installed from your dealer)

2014-18 HUSQVARNA FE 250/350/450/501 Models (Must have EURO map installed already from your dealer)

Please specify in the notes what type of power you are looking for.  More agressive, less agressive. 

We use the UST (User Setting Tool) that was made by KTM to make changes to your ECU.  I can make timing adjustments, Acceleration fuel changes, and general fuel changes to all RPM ranges.  I have very close settings for all these bikes. 

After purchasing online you will receive an email with shipping details from us.  You will include all your information in the box along with exact year and model of your bike.  You will ship your ECU directly to us and we will turn around in 1 day with the Custom Map installed for your exact year and bike model. 

This modification is 100% For Closed Course Racing Use only. Not Intended for Street Use!  Does not conform to Carb/ EPA laws and regulations and is not legal for use upon a highway. By ordering this product you agree to these terms. 

We recommend shipping by Priority Mail for quickest service normally 2-3 days across the country.  We will return ship your ECU by Priority Mail with Insurance and Signature Confirmation.

ECU tuning

Thank you Chris. Smoother acceleration, and cooler running for desert riding.

Wow! I'm trying to say it's in my head, but there is no way. She's angry!...explosive, authoritative, snappy, doesn't like to have her front wheel on the ground. Idles strong, runs with a purpose. I don't know how to explain it other than this... I wish I understood...

Ecu mapping

First off I have been riding my 2017 fe501 for 6 months now. I have done most of the mods and was ready to get more power. I was looking to get my ecu mapped by Blais Racing but I was in the middle of a hare scramble series. I reached out to Chris and needed a quick turn around. I overnighted it to them and they overnighted back to me that same day. When I plugged it in and fired it up I noticed right away this is what I was looking for. What a beast. The throttle is so much more crisp and power gains are throughout every gear. Great customer service and an excellent company. Thank you Blais Racing!

I rode the FE 250 today with the FMF 4.1 and your ecu re-tune and all I can say is WOW! If you recollect from this email thread, I was a bit underwhelmed by the ecu tune (although it was a noticeable improvement) and I was wanting more. You recommended the FMF 4.1 muffler which I bought and the combination of this and your ecu tune really did the trick. The bike pulls so much harder on the bottom and everywhere else. I'm able to pull a gear taller everywhere and it just wants to rip. I think your tune just couldn't do its thing until I pulled the cork out of the exhaust.

Euro Map Update!

Just an update. The 500 has been running great and power is endless. I can't even get up in the rpm before it wants to throw me off. Thanks for the tuning on the ecu Chris.
