My understanding was that any messing with the ignition timing was against the rules, (I'm ashamed to admit that I haven't actually read the latest version).

To save you looking, but you should really read the rules.

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.

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.
