PRO HV-8 Injector Driver
The PRO HV-8 Injector Driver delivers high voltage, current, and advanced diagnostics for precise injector actuation — from street builds to motorsport. Compatible with Gasoline Direct Injection (GDI) and high-flow conventional (PFI) injectors in low or high impedance, it offers 8 channels and 2 pump outputs on a single hardware, with rapid opening, efficient atomization, and stable operation under extreme conditions.

The PRO HV-8 blends high-voltage actuation, intelligent peak-and-hold control, and advanced diagnostics into a single compact and robust platform. Its architecture handles everything from high-pressure GDI injectors to high-flow conventional (PFI) injectors with the same precision and repeatability.

- A single driver for Direct Injection (GDI) and Conventional Injection (PFI).
- Configuration and diagnostics via CAN (VisionFT/FTManager), or via DBC for use with third-party CAN tools.
- Electronic and thermal protections with LED indication.
- Three-stage control strategy: BOOST → PEAK → HOLD, delivering better repeatability under short pulses and high RPM.
Boost stage
The Boost stage operates with a configurable voltage up to 65V and a configurable maximum current up to 25A, accelerating injector coil magnetization and reducing opening time. The result is lower latency on short pulses and faster actuation response.
Peak & Hold control
Following the Boost stage, the Peak & Hold control sustains a peak current of up to 25A and a hold current of up to 25A, ensuring complete injector opening without overheating throughout the entire pulse — especially well-suited to GDI injectors as well as conventional injectors.
Channels and communication
- 8 independent, configurable channels for Direct or Indirect Injection.
- 2 additional channels for controlling the high-pressure fuel pump regulator valves. Each channel operates in isolation — semi-sequential.
- CAN network (VisionFT/FTManager) for configuration and monitoring.
- 35-pin connector with dedicated harness.
Configurable parameters
Real-time adjustments via CAN (ECU integration):
- Boost, peak, and hold currents
- Boost, peak, and hold voltages
- Multiple injection profiles
- Multi-pulse actuation
- Parameter updates supported within the safety monitoring system
Monitoring and protections
- Injector or driver fault detection with LED indication.
- Injector fault detection: overcurrent, open circuit, and short circuit to ground/positive.
- Driver thermal warnings and protection.
- Battery overvoltage and undervoltage protection, including "low boost" power-loss detection.
- Operating range: -20°C to 125°C (-4°F to 257°F).
Installation
- Install with the battery disconnected and the harness disconnected from the module.
- Run the power ground directly to the battery negative, without splices (do not connect to chassis, block, or cylinder head).
- Keep the harness as short as possible; trim excess and avoid coiling wires.
- Protect against heat, moving parts, and sharp edges; use protective sleeves/grommets.
Construction and durability
- Precision-machined aluminum housing with high thermal dissipation.
- Sealed against dust, moisture, and condensation.
- Suitable for street and track operation.
