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.
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.
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.
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.
