• The FuelTech FTSPARK-4 GEN3 MAX2000 represents the most powerful Capacitive Discharge Ignition (CDI) system ever developed by FuelTech. Delivering up to 2000mJ of ignition energy per channel, significantly higher spark current and duration, advanced CAN bus integration, and a new Extended Spark mode, the GEN3 MAX2000 is engineered to ignite the most demanding mixtures used in modern motorsport.

  Designed for engines operating under extreme cylinder pressure, high boost, alcohol fuels, and nitromethane applications, GEN3 MAX2000 ensures stable combustion where conventional ignition systems reach their limits.

  Its reliability and system integration are built for the most demanding motorsport environments on the planet.

Features

2000mJ Per Channel — Extreme CDI Ignition Energy

At the core of the FTSPARK GEN3 MAX2000 is a completely redesigned ignition architecture developed to push the limits CDI ignition performance:

• Up to 2000mJ of ignition energy per channel — extremely high spark intensity for engines operating under extreme cylinder pressure 
• 475–500V primary coil voltage, helping prevent misfires in high boost and high compression applications 
• Up to 175A primary coil current when paired with the FuelTech Racing CDI Coil designed specifically for FTSPARK systems 
• Strong spark current and reliable ignition performance even when operating at reduced ignition energy levels down to 150mJ 
• Increased spark current and extended spark duration for improved combustion stability across a wide range of engine conditions 

Multispark Mode — Ignite the Most Difficult Mixtures 

The new Multispark mode expands the operating envelope beyond traditional CDI ignition systems:

• Programable multispark configuration: fire a series of sparks rather than a single spark per combustion cycle
• Enables stable ignition of extremely rich air/fuel mixtures — ideal for high boost, high compression, alcohol, and nitromethane applications
• Provides ignition performance comparable to high-energy inductive systems when operating with lean mixtures
• Ensures consistent combustion from idle conditions through maximum cylinder pressure

Programmable Energy & Advanced CANBUS Integration

The FTSPARK GEN3 MAX2000 offers extensive integration flexibility for professional engine builders and calibrators: 

• Programmable ignition energy via CAN communication or dedicated energy level adjustment input — enabling control of ignition power
• Advanced per-channel diagnostics via CANBUS for real-time system monitoring and fault detection
• CAN communication with the full FuelTech ECU lineup — ignition channel data can be logged directly through the FuelTech datalogger
• Single-wire serial bus (multiplexed trigger input) — all ignition channels triggered from a single ECU output, simplifying wiring and freeing ECU resources for additional strategies 
• Compatible with a wide range of motorsport ECUs through motorsport-standard ignition trigger input architecture 

Built for the Most Extreme Racing Conditions 

Every design decision in the GEN3 MAX2000 prioritizes durability and long-term reliability under race conditions: 

• Reinforced internal construction for improved resistance to vibration, impact, and extreme G-forces
• High-quality automotive-grade connectors for dependable electrical connections in harsh motorsport environments
• Advanced thermal design with increased heat dissipation capacity and improved heat exchange for lower operating temperatures and extended duty cycles 

Engineered for drag racing, rally, off-road, and endurance applications where ignition performance and reliability are critical. 

Direct Drop-In Upgrade from FTSPARK GEN2

Upgrading from GEN2 is as straightforward. GEN3 MAX2000 maintains:

• Identical pinout — no rewiring required
• Same mounting points — direct mechanical replacement

Full GEN3 MAX2000 performance gains are available as a direct swap, keeping installation time and downtime to a minimum.
