New FuelTech PRO HV-8 Injector Driver. One Driver. Two Technologies.

The PRO HV-8 is a high-voltage, high-current automotive module engineered for precise actuation of GDI (Direct Injection) and PFI (conventional) high-flow injectors, in low or high impedance. Its Boost → Peak → Hold architecture ensures fast opening, repeatability under short pulses, and stable, accurate operation throughout the entire injection cycle.

Ideal for street, race, and daily-driver vehicles using GDI or high-flow conventional injectors. Works engines with up to 8-cylinders, naturally aspirated or turbocharged, running ethanol, gasoline, or blends.

Yes — not by generating power on its own, but by delivering the precise control and actuation speed that allow the engine to unlock its full potential safely. Direct benefits include: Drastically faster injection response, with conventional-injector dead time reduced from approximately 1.4 ms to 0.3 ms. Stable, consistent idle even under varying electrical load (alternator, fans, headlights), thanks to high-voltage regulation. More linear fuel maps and improved atomization across all regimes, simplifying calibration and improving drivability.

Repeatability under short pulses and at high RPM, validated up to 12,000 RPM. Ability to run a single bank of high-flow injectors on high-power engines (eliminating dual-bank setups), with greater operational safety and lower risk of damage from a lean condition. Together, these gains translate into a more consistent engine that's easier to tune and capable of operating safely in regimes that were previously impractical with conventional drivers.

Yes. Injection becomes smoother at low load, misfires are reduced, idle is stabilized, and high flow injectors can be used without sacrificing day-to-day driveability.

The PRO HV-8 is compatible with most injectors: GDI injectors: Bosch, Hitachi, EcoBoost, TSI, BMW GDI, and similar. PFI injectors in low and high impedance, including high-flow units.

8 independent injector channels, with support for simultaneous (overlap) actuation across them. 2 additional channels for fuel pumps or actuators, operating independently (no overlap between the two).

The Boost phase is the initial stage of the actuation cycle, in which the PRO HV-8 applies up to 65V and up to 25A — well above the 12–14V available from the vehicle's main supply.

This elevation accelerates injector coil magnetization, drastically reducing opening time — in conventional injectors, dead time can drop from approximately 1.4 ms to 0.3 ms. The practical result is lower latency, greater dosing precision, and near-instant response — factors that are essential for control under short pulses, high RPM, and high-pressure GDI applications.

The PRO HV-8 supports a peak current (Peak) of up to 25A and a hold current (Hold) of up to 25A. The peak ensures complete mechanical opening of the injector — complementing the high-voltage Boost stage that accelerates that opening — while the hold keeps the valve open in a stable manner throughout the pulse, without excessive heating. This combination delivers consistent, repeatable response across a range of injector types, including high-flow and low-impedance models.

PRO HV-8 configuration is performed entirely over the CAN network, with no need for additional proprietary hardware. Customers in the FuelTech ecosystem use VisionFT or FTManager for parameterization and diagnostics; projects using third-party ECUs and tools can work directly with the DBC file provided by FuelTech. Through the interface, you can adjust boost, peak, and hold currents and the boost-stage voltage in real time during setup or operation.

Yes. It is brand-independent and integrates with any OEM or aftermarket ECU that sends injection signals by pulse or CAN.

Yes. It maintains stability and repeatability even under very short pulses or high engine speeds (up to 12,000 RPM).

The system includes automatic detection of: Open circuit, Short circuit, Supply voltage drop, Power loss on the high-voltage (Vboost) stage, and Thermal protection.

Yes. On a single platform, the PRO HV-8 combines both injection topologies (GDI and PFI), eliminating the need for additional modules and duplicated setups. For drag racing tuners, this often replaces the need for dual injector banks — a single set of injectors becomes sufficient, without sacrificing flow or precision.

No — they serve different scenarios. The Peak & Hold PRO remains the recommended choice for conventional injection within its segment. The PRO HV-8 is the right choice when the project requires: A single bank of high-flow injectors on high-power engines (no dual bank); Stable idle with high flow injectors; GDI injector actuation*. The PRO HV-8 is not plug-and-play: it requires its dedicated harness. *GDI control is available on the VisionFT line in Beta, subject to consultation with FuelTech Technical Support.

The PRO HV-8 Injector Driver is compatible with any ECU capable of direct injection control. The FT700 supports Direct Injection in Beta mode; to gain access to this version and obtain setup guidance, please contact Technical Support.

The PRO HV-8 Injector Driver is compatible with any ECU capable of direct injection control. However, the PowerFT line does not include this feature.
