Fueltech Peak & Hold PRO Injector Driver FuelTech’s Peak & Hold PRO Injector Driver is designed to control low impedance fuel injectors OR control 8HP transmission solenoids! Designed to control low impedance fuel injectors Features 8 channels and a 26-way automotive connector. Several integrated motor protections in case an injector or connection fails 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 FuelTech ECUs require a Peak & Hold Pro to properly control the ZF 8HP transmission because its solenoids are low-impedance and demand precise current (peak-and-hold) control not just standard PWM voltage. The module ensures fast, consistent shifts while preventing solenoid damage. Peak and Hold PRO Injector Driver Manual
