In the case of the Subaru engines with their relatively high compression ratios, we've found that timing should be limited to around 25-26 degrees when running on 91 octane mogas so that detonation cannot occur. Having the ignition timing too far advanced for the fuel octane is the leading cause of detonation, running the AFR too lean also contributes to detonation.
