FuelTech Unveils the Next Generation of Ignition and Fuel Injection Control: FTSPARK GEN3 MAX2000 & PRO HV Injector Driver

December 11, 2025

FTSPARK GEN3 MAX2000

Maximum Spark Energy, Control, and Reliability

FuelTech is set to unveil the FTSPARK GEN3 MAX2000 ignition system at the 2025 PRI Show, marking the most significant advancement yet in the FTSPARK product line. Designed for the extreme demands of modern motorsport, GEN3 MAX2000 delivers unprecedented ignition performance, improved durability, and next-level data and integration capability — all while maintaining seamless compatibility with existing GEN2 installations.

Unmatched Ignition Energy and Performance

At the core of FTSPARK GEN3 MAX2000 is a completely redesigned ignition architecture capable of delivering up to 2000mJ per channel, establishing a new benchmark in high-energy CDI systems. Beyond peak energy, GEN3 MAX2000 provides:

Higher spark current than previous generations
Increased spark duration, improving combustion stability
High output voltage at any energy level, maintaining robust spark performance even at 150mJ

While the market increasingly requires ignition systems capable of operating at much lower energy levels, previous FTSPARK generations were limited to a minimum of roughly 450–500 mJ. The new GEN3 MAX2000 architecture breaks this barrier, delivering precise control down to 150 mJ without sacrificing discharge quality or reliability.

This combination allows FTSPARK GEN3 MAX2000 to ignite extremely rich air/fuel mixtures with consistency, making it an ideal solution for high-boost, high-compression, alcohol-based, or nitromethane applications where reliable combustion is critical.

Expanded Channel Capability and Control Flexibility

FTSPARK GEN3 MAX2000 supports up to 8 fully independent ignition channels, giving engine builders and calibrators a powerful solution for multi-cylinder racing platforms.

Engine control integration is more flexible than ever:

Advanced individual-channel diagnostics via CANBUS
Operation with a single ignition output, freeing ECU resources for additional strategies
Motorsport-standard ignition input compatibility, ensuring seamless use with any brand of ECU

Whether building a new platform or upgrading an existing one, GEN3 MAX2000 delivers maximum freedom without sacrificing reliability or functionality.

Built for the Harshest Motorsport Environments

Durability, ruggedness, and reliability were central to the GEN3 MAX2000 redesign. The new unit features:

A precision-machined aluminum enclosure
IP67 waterproofing for total environmental protection
Enhanced structural design for superior mechanical resistance to vibration, shock, and extreme G-forces

From drag racing to off-road endurance, FTSPARK GEN3 MAX2000 is engineered to survive conditions where conventional ignition systems fail.

Drop-In Upgrade from GEN2

FuelTech ensured the upgrade path from GEN2 is as simple as possible. FTSPARK GEN3 MAX2000 preserves:

Identical pinout
Matching mounting positions

This allows teams to upgrade directly with minimal rewiring or mechanical changes — gaining all the benefits of GEN3 MAX2000 performance with the convenience of a direct swap-in replacement.

PRO HV INJECTOR DRIVER

A New Standard for High-Energy Injector Control Across GDI and port injectors both high or low impedance.

FuelTech is set to introduce the PRO HV Injector Driver, a breakthrough module engineered to meet the extreme electrical and dynamic demands of modern engines — from high-pressure Gasoline Direct Injection (GDI) systems to conventional high-flow Port Fuel Injection (PFI) applications.

Designed for motorsport, R&D environments, performance workshops, and OEM integrators, the PRO HV Injector Driver blends high-voltage actuation, intelligent peak-and-hold control, and advanced diagnostics into a compact, robust, and fully configurable platform. Shape

High-Voltage Actuation and Intelligent Peak & Hold Control

At the heart of the PRO HV Injector Driver is its 65V / 17A Boost stage, enabling extremely rapid energization even for demanding GDI injectors — a fundamental requirement for precise fuel delivery under high cylinder pressures.

Once the injector is energized, the module transitions seamlessly through:

Peak Phase for commanding full mechanical lift
Hold Phase for stable and repeatable injection across the entire pulse

This fully integrated Boost → Peak → Hold cycle ensures:

Significantly reduced injector opening time
Consistent behavior at high RPM and high-load operation
Improved combustion stability in both stratified and homogeneous modes
Reliable performance for low-impedance injectors with extremely shortened pulse demands

These capabilities allow the PRO HV Injector Driver to deliver OEM-grade precision previously accessible only through specialized factory electronics.

Full Support for GDI Platforms — Up to 8 Direct Injectors, and 2 GDI fuel pumps

The PRO HV Injector Driver provides complete GDI capability, supporting up to eight direct injectors, each with fully independent current profiles.

Its high-voltage actuation and precise current regulation deliver:

Dramatically improved injection timing accuracy
Fast and repeatable opening under high pressure
Multi-pulse capability for advanced combustion strategies
Full flexibility in injection order — any cylinder, any sequence
CAN-based configuration for currents, timings, strategies and safety limits
Allows control of up to 2 GDI fuel pumps

Extreme Control for port injectors both high or low impedance

Big power engines — including forced induction, ethanol or methanol-based setups and drag racing applications — depend heavily on large port Injectors both high or low impedance.

The PRO HV Injector Driver delivers what traditional drivers cannot:
a massive reduction in dead time, transforming a typical 1.4 ms delay into as little as 0.3 ms.

This leap in response time provides:

Superior atomization at low load
Smooth idle and improved transient fueling
More linear fuel maps
Ability to run large injectors without sacrificing drivability
Stable high-current operation even under sustained high duty cycles

For drag racing teams and tuners, this often eliminates the need for dual-injector setups — a single set becomes sufficient. Shape

Advanced Diagnostics and Safety Systems

The PRO HV Injector Driver incorporates P&H PRO Injector Driver-level diagnostics, continuously monitoring:

Short circuits
Open load conditions
Overcurrent and overheating
Abnormal voltage behavior
Injector performance deviations during boost, peak, or hold phases

These systems ensure reliability in extreme environments, providing actionable feedback for engineers, tuners and safety-critical applications.

Built for Harsh Automotive and Motorsport Conditions

The PRO HV Injector Driver features a precision-machined aluminum enclosure offering:

Excellent thermal dissipation
High vibration and mechanical resistance
Sealed housing with automotive-grade environmental protection
Stable operation in high-temperature, high-load environments

From endurance racing to dyno development, the module is engineered for reliable performance where electrical and mechanical stress are highest. Shape

One Platform, Two Advanced Injection Topologies

For GDI:

Support for up to 8 high-pressure injectors
Support for up to 2 GDI fuel pump controls
65V / 17 A boost for rapid lift
OEM-grade timing and multi-pulse capability
Ideal for modern engines

For PFI low or high Impedance:

Ultra-fast actuation with dramatically reduced dead-time
Perfect for high-flow injectors
Eliminates some dual-bank requirements
Reliable control at high currents and RPM

The PRO HV Injector Driver unifies these capabilities in a single compact platform, adaptable to both production and high-performance environments.

REAL WORLD IMPACT: A RADICALLY SIMPLER AND MORE ACCURATE TUNE

When dead time minimized and equalized, the entire tuning process is simplified. Because the injector now opens nearly a full millisecond faster across the board, you can remove that time from the entire fuel map, gaining immense resolution and precision at very pulse widths.

"Basically, when you substitute a conventional peaK and hold for a high voltage one, you will probably reduce the entire map by about 1ms."

AVAIABILITY

The FTSPARK GEN3 MAX2000 and PRO HV Injector Driver are scheduled for release in 2026, with FuelTech set to announce the official launch date soon. As the release window approaches, more details, specifications, and integration resources will be shared with the racing community.
