Standard Electronic Control Unit (SECU)

In Simple Terms

The SECU is a standardized computer control unit that all F1 teams must use to manage their car's engine and power unit functions. This ensures fair competition by preventing teams from gaining unfair advantages through advanced electronics, while still allowing teams to develop their own strategies within the permitted parameters.

• All teams use identical FIA-supplied standard electronic control units to level the playing field
• The SECU controls critical engine and power unit management functions
• Teams cannot modify or replace the SECU with their own systems
• Violations of SECU regulations can result in significant sporting and technical penalties
