Below you find the Text in FIA Appendix K 2015 about ignitions.
TECHNICALREGULATION FOR
PRODUCTION ROAD CARS
Cars of
Period F(62-65) homologated with electronic ignition systems and cars of Periods G1(66-69)
and G2(70-71) may use a non-period electronic ignition system provided this system is
triggered by contact breaker(s), utilises an ignition coil with a minimum
resistance of 3 ohms, the spark is distributed by a rotor arm and the timing of
the spark is controlled entirely by mechanical means. Multi-spark systems and
systems where the timing of the spark is altered electronically are not
permitted.
Cars of
Period G1(66-69) and G2(70-71) with electronic ignition systems may use magnetic or optical
triggering.
Cars of
Period H1(72-75) onwards may use ignition coils with less than 3 ohms resistance
and/or multi spark systems.
Electronic
ignition systems which control the timing of the spark are permitted only if
this was a period modification.
APPENDIX VIII
Modifications authorised
for cars of Periods E, F and G1 for Series Production Touring Cars and Standard
Grand Touring Cars.
1.8 The addition of
an electronic ignition system is not permitted, nor is that of an electronic
rev.limiter.
