Default Variable ignition timing (100LL no longer available at RHV).

Is there such a thing as a kit to add variable ignition timing for GA aircraft?

Heading and subject asking 2 different questions ??
I'm assuming variable valve timing is out unless you install a Viking engine.

Ignition, there are different options available.
article in Kitplanes magazine on the different options.

Default SDS to the rescue

Go with SDS fuel and ignition, EM-5F system, and your worries are over.
I have an 0-360 8.5 compression ratio and I run Costco premium.
Yes I have the 6 port Andair valve for return lines to tanks and all SS/teflon lines.
Starts same cold or hot.
Problem solved.

Default Dynamic spark advance.

By ignition timing, I mean advancing or retarding the spark to compensate for lower octane fuel(s).
