Description

The Peak and Hold PRO Injector Driver is an advanced current control module designed to control low impedance injectors.

It has 8 channels for injectors, a 26-way automotive connector and different levels of protection for the engine in case an injector or connection fails. In general, competition and/or high-flow injectors use low-impedance internal coils with a resistance of less than 7 Ohms . This allows them to have a much shorter response time than a high impedance injector.

These coils with lower impedance imply a higher drive current and require control of the opening current and nominal “peak” current and “hold” current , otherwise the injector can quickly heat up and burn out.

With the Peak and Hold PRO Injector Driver control, it is possible to apply a higher initial current to allow the injector to quickly open the “peak” current and then reduce the current to a value that, in general, corresponds to 1⁄ 4 of the initial “hold” current .

The Peak and Hold PRO Injector Driver module is also compatible with high impedance injectors above 7 ohms , making it possible to use all protection and diagnostic functions.

This reduces the injector's dead time - the time between the injector receiving the electrical stimulus and actually starting to inject fuel .

Characteristics

• Current control driver for low impedance injectors
• 8 channels
• Current selectable via software up to 12A Peak and 3A Hold
• CAN communication for protections and diagnostics

Installation

FuelTech offers some options to facilitate your installation:

• 2 meter wiring harness is recommended for new designs, with module connector and male/female CAN connectors
• Connector kit assists in the manufacturing/modification process of your electrical harness.
• Adapter harness was developed for projects replacing two Peak and Hold with the new P&H PRO INJECTOR DRIVER, making installation easy and quick!

Protections

The Peak and Hold PRO Injector Driver is capable of identifying the following faults:

• Injector disconnected
• Shorted injector
• Overheating
• Module integrity check failures generate status event and are written to the log. For each failure it is possible to define the protection level, choosing:
• Alert in the ECU the PRO Injector Driver module sends an alert to the PowerFT ECU
• Protection is defined on the map, in the Alerts Configuration, through the ECU or FTManager screen
• Disable module o Turns off the injectors o Turns off the relay output o Turns off the second module if the communication wire is connected

Diagnosis

• Individual detection of disconnected or shorted injector.
• Individual log channels with time to reach peak current, allowing injector defects to be identified.
• Logs battery voltage and module temperature.
• Log records the defined current settings.
