8.2 Control electronics :
8.2.1 All components of the engine and gearbox, including clutch, differential and all associated actuators must be controlled by an Electronic Control Unit (ECU) which has been manufactured by an FIA designated supplier to a specification determined by the FIA.
The ECU may only be used with FIA approved software and may only be connected to the control system wiring loom, sensors and actuators in an manner specified by the FIA.
8.2.2 All control sensors, actuators and FIA monitoring sensors will be specified and homologated by the FIA.
Each and every component of the control system will be sealed and uniquely identified and their identities tracked through their life cycle.
These components and units may not be disassembled or modified in any way and seals and identifiers must remain intact and legible.
8.2.3 The control system wiring loom connectivity will be specified by the FIA.
8.2.4 Pneumatic valve pressure may only be controlled via a passive mechanical regulator or from the ECU and its operation will be monitored by the ECU.
8.2.5 The car hydraulic system will be monitored by the ECU.
8.2.6 The ECU will be designed to run from a car system supply voltage of 12V nominal provided by a homologated voltage regulator.
8.3 Start systems:
Any system, the purpose and/or effect of which is to detect when a race start signal is given, is not permitted.
8.4 Data acquisition :
Any data acquisition system, telemetry system or associated sensors additional to those provided by the ECU and ADR must be physically separate and completely isolated from any control electronics with the exception of the primary regulated voltage supply, car system ground and a single communication link to the ECU and ADR.
8.5 Telemetry :
8.5.1 Telemetry systems must operate at frequencies which have been approved by the FIA.
8.5.2 Pit to car telemetry is prohibited.
8.6 Driver controls and displays :
Any electronic modules used for driver information displays and switch inputs must be supplied by an FIA designated supplier to a specification determined by the FIA and be suitably housed by each team.
8.7 Driver radio :
Other than authorised connections to the FIA ECU, any voice radio communication system between car and pits must be stand-alone and must not transmit or receive other data. All such communications must be open and accessible to both the FIA and, where appropriate, broadcasters.
