Unleash the full potential of your 2024 KTM 350/500 EXC and 2024 Husqvarna FE350/501 with the Vortex ECU unit. Loaded with features and precision-tuned for optimal performance, this ECU is your ticket to an enhanced riding experience.


Key Features:

  • Pre-Programmed Performance: Equipped with 10 Performance Fuel & Spark timing maps, the Vortex ECU is pre-programmed to deliver instant plug-in performance without the need for extensive modifications.

  • User-Friendly Adjustments: Three additional switches allow users to trim fuel in Lo, Mid, and Hi throttle openings, offering a customizable riding experience. Adjustments require only a screwdriver, and integrated switches provide visual feedback.

  • Seamless Integration: The ECU seamlessly plugs into the bike's standard wiring harness, interfacing with engine sensors (ECT, IAT, MAP, TPS, CPS) to optimize fuel and spark timing for peak power delivery in various conditions.

  • Performance Gains: Experience gains in top-end power and improved bottom-end throttle response. "Power" settings deliver increased top-end power, while "Traction" settings offer a smoother and more tractable ride.

  • Improved Starting and Flameouts: Vortex has included tune parameters that enhance starting and almost eliminate flameouts experienced with some EFI MX bikes, providing a hassle-free riding experience.

  • Full Programmability: The ECU is fully programmable (software not supplied), offering extensive parameters for customization, including Rev Limits, Throttle Enrichment & Decay time, Fuel timing, High-Resolution Mapping, Dwell Time, Voltage Output, and more.

  • Real-Time Logging & Graphing: In addition, real-time logging and graphing of many parameters (when combined with the ECU Software - not included) allow for comprehensive monitoring and analysis.

  • Robust Design: The robust design is fully encapsulated and O-ring sealed, ensuring durability and longevity even in challenging riding conditions.

  • V-Boost Technology: Enjoy a programmable Voltage Boost Circuit (V-Boost) that maximizes Spark Energy across the entire rev range for optimal performance.

  • Rev Limit Options: Higher/Lower Rev Limit options are available where required, providing flexibility based on your riding preferences.

  • Diagnostic Flash Codes: The ECU features diagnostic flash codes that test for sensor faults and flash codes to the OEM FI light for quick and easy diagnostics.

  • Race-Proven Reliability: Developed and tested by Vortex Ignitions engineers in collaboration with race teams worldwide, ensuring race-proven reliability.

  • Warranty: Covered by a 12-month warranty against manufacturing defects, providing peace of mind and confidence in the product.

  • Note: The ECU does not come standard with a handlebar switch; however, it is available as an optional extra. No switch eliminator is needed when not running the handlebar switch, unlike other CDI products.
