Product Information

Welcome to our Custom ECU Mapping Service for 2011-2020 KTM and 2014-2020 Husqvarna 250/350/450/500/501 4-stroke closed-course MX bikes! Please read the details below before ordering.


Service Overview:

  • Compatibility: Specifically designed for 2011-2020 KTM SXF/XCF and 2014-2020 FC/FX/FS Husqvarna closed-course 4-stroke fuel-injected MX bikes.
  • Flameout Reduction: Our ECU Tuning service can reduce flameouts by approximately 50%, providing enhanced performance.


Tuning Details:

  • Re-Flash/Tuning: This is a re-flash/tuning service performed on your stock KTM & Husqvarna ECU. After ordering, ship your ECU to us. We recommend our 7 Ounce Clutch weight for additional benefits.
  • Clean ECU Settings: We offer refined ECU settings for KTM SX-F/XC-F and Husqvarna FC/FX/FS models, addressing fueling, timing, and Accelerator pump fueling.
  • Low-End Fueling Issue: Our tuning addresses the common low-end fueling issue, a root cause of flameout problems.
  • Fine-Tuning Capability: The software allows fine-tuning of the ECU program across all throttle positions and RPMs.
  • 30-Day Satisfaction Guarantee: Try the tuned ECU for 30 days, and if unsatisfied, we'll revert to stock settings and provide a refund.  If your ECU is not programmable for any reason there will be a $25 charge for diagnostic service.


Map Switch and TC Information:

  • For bikes with Map Switch and TC on the handlebars, fueling changes affect all maps, while ignition changes affect Map 1. Map 2 (aggressive map) adds a preset amount of ignition timing to Map 1. TC functions similarly by detuning ignition timing.


Compatibility Limitations:

  • 2020-2024 KTM XCF-W and EXC-F Models: Cannot be programmed.
  • EURO Map Requirement: For 2012-2019 KTM 250/350/450/500 EXC/EXC-F/XCF-W and 2014-2019 Husqvarna FE 250/350/450/501 models, an unlocked ECU with the EURO map is required. If for any reason you send an ECU that is no programmable there is a $25 service fee.


Ordering Instructions:

  • Power Type Specification: In the order notes, specify the desired power type—more aggressive or less aggressive.


Shipping and Return Details:

  • After purchase, you'll receive shipping instructions via your Order Confirmation Email. Ship your ECU to us, and we'll return it within 1 day with the Custom Map for your specific year and bike model.
  • We recommend Priority Mail for quick and secure shipping. The return shipment includes $100 insurance.
