Class A 1.6.31 Ignition/Engine Control System Ignition/engine control system (ECU) may be modified or changed. Any alteration that allows the number of degrees of spark advance beyond the manufacturers standard specification is not allowed. So does this mean physically altering the original engine parts is a no-no? The use of flash memory (‘flash RAM’) for fuel injection mapping is allowed. An additional control unit to change the fuel mixture may be fitted. FIM ignition maps are ok? As are devices to alter fuel mapping? |
