Frequently Asked Questions (FAQ)
Designed for gasoline engines with 1 to 4 cylinders, trijekt bee is ideal for applications with limited installation space and low weight – such as UAVs, industrial systems, or research setups.
trijekt bee is available in two versions:
– as a dedicated ignition control unit, or
– as a complete ignition and injection control system.
CAN bus and RS232 interfaces enable communication with other control units or measurement systems, while inputs and outputs are freely programmable for flexible system integration.
Yes – its compact housing and low weight make it particularly well suited for use in unmanned aerial, ground, or marine systems.
Programming and diagnostics are carried out via the trijekt software, which allows map tables, control parameters and sensor assignments to be edited comfortably and operational data to be logged and analysed.
