01/01/2018    All ECUís to be used on production group race cars are to be presented to the technical chairman of the club the driver wishes to race with before the start of the race season or before the car is raced. This is so the ECU can be checked for tampering or modification. The ECU will then be sealed with a SEGTO seal. If this seal is broken or tampered with, the ECU will be deemed to be illegal.
