Open Diagnostics Guide →Important Installation Information
uaEFI is a universal programmable engine management system and requires application-specific wiring and configuration.
Always verify the current uaEFI interactive pinout before connecting the ECU. Incorrect wiring of power supplies, grounds, ignition coils, injectors, electronic throttle bodies or sensors can damage the ECU or connected components.
Standard ignition outputs are primarily intended for smart ignition coils with integrated ignition drivers. Conventional ignition coils require suitable ignition drivers.
Injector outputs are intended for high-impedance fuel injectors. Low-impedance injectors must not be connected directly without an appropriate solution.
Electronic throttle control should only be activated after throttle and accelerator pedal sensors have been correctly wired, checked and calibrated.
