What is the PRO HV-8 Injector Driver? \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2. Which vehicles is the PRO HV-8 suitable for? \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIdeal 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3. Does the PRO HV-8 improve engine performance? \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes — 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.\u003c\/p\u003e\n\u003cp\u003eRepeatability 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. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e4. Does the PRO HV-8 help with drivability and idle? \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. 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. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e5. Which injector types does the PRO HV-8 support? \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e6. How many channels does the module have? \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e8 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).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e7. What is the Boost phase and why does it matter? \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e8. What are the supported Peak \u0026amp; Hold currents? \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e9. How is the PRO HV-8 configured? \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePRO 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e10. Does the PRO HV-8 work with any ECU? \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. It is brand-independent and integrates with any OEM or aftermarket ECU that sends injection signals by pulse or CAN.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e11. Does the PRO HV-8 improve short-pulse and high-RPM control? \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. It maintains stability and repeatability even under very short pulses or high engine speeds (up to 12,000 RPM).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e12. What protections does the module include? \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe system includes automatic detection of: Open circuit Short circuit Supply voltage drop Power loss on the high-voltage (Vboost) stage Thermal protection.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e13. Does the PRO HV-8 replace separate PFI and GDI modules? \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e14. Does the PRO HV-8 replace the Peak \u0026amp; Hold PRO? \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo — they serve different scenarios. The Peak \u0026amp; 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e15.
