FuelTech's Peak & Hold PRO FuelTech’s Peak & Hold PRO Injector Driver is an advanced module designed to control low impedance fuel injectors at a professional level, featuring 8 channels, 26-way automotive connector, and several integrated motor protections in case an injector or connection fails. It is capable of delivering 2 to 12 Amps of software-selected current per channel and has an internal temperature sensor, fault diagnosis, and protection against high temperature. The module is housed in an anodized aluminum and plastic case and allows firmware updates through CAN bus communication.
Peak and Hold PRO Injector Driver is an advanced module designed to control low impedance injectors at a professional level, featuring 8 channels, 26-way automotive connector and several motor protections levels in case an injector or connection fails.
In general, racing high-flow injectors use low impedance internal coils (with less than 7 Ohms resistance). That allows them to have a much shorter response time than a high impedance injector.
These lower impedance coils require a current control, starting with a higher current at opening stage (peak) and lower current when opened (hold), otherwise the injector can quickly warm up and burn.
With PRO Injector Driver it is possible to apply a higher initial current, allowing quick opening of the injector and then reduce the current to, in general, 1⁄4 the peak current.
Therefore, reducing injector’s deadtime (time between the injector gets energized and effectively sprays fuel).
