The FuelTech PRO HV-8 is a high-voltage injector driver that handles both gasoline direct injection (GDI) and high-flow port (PFI) injectors, low or high impedance, from one module. It uses a three-stage Boost, Peak and Hold strategy: a boost stage of up to 65V speeds coil magnetization so the injector opens faster, then peak and hold control keeps it fully open without overheating. FuelTech states conventional-injector dead time can drop from about 1.4 ms to 0.3 ms, with repeatable control validated up to 12,000 RPM.
- 8 independent injector channels for direct or port injection
- 2 additional channels for high-pressure fuel pump regulator valves
- Boost stage: configurable voltage up to 65V, current up to 25A
- Peak current up to 25A, hold current up to 25A
- Configuration and diagnostics over CAN (VisionFT / FTManager) or via DBC file for third-party tools
- Fault detection: overcurrent, open circuit, short to ground or positive, with LED indication
- Thermal protection plus battery over/undervoltage protection
- 35-pin connector with dedicated harness
- Operating range: -20°C to 125°C (-4°F to 257°F)

Compatibility
Works with GDI injectors (Bosch, Hitachi, EcoBoost, TSI, BMW GDI and similar) and PFI injectors in low and high impedance, including high-flow units. It is brand-independent: any OEM or aftermarket ECU that sends injection signals by pulse or CAN can drive it. Suited to engines up to 8 cylinders, naturally aspirated or boosted, on gasoline, ethanol or blends.
What's included
- 1 PRO HV-8 module
- 1 installation and operation manual
- Connector kit or 6 ft unterminated harness, if selected
Installation notes
- Install with the battery disconnected and the harness unplugged from the module
- Run the power ground directly to the battery negative with no splices; do not ground to chassis, block or cylinder head
- Keep the harness as short as possible and avoid coiling excess wire
- Protect wiring from heat, moving parts and sharp edges with sleeving and grommets
