Re: Low octane timing flag I don't know the answer to this... but from what I've read and what would make sense
Constant Knock Retard would probably cause it... Getting it just at certain RPMs or only in certain gears probably wouldn't... but getting KR all the time would probably set it....
Like I said though, I dont know what values GM uses to determine low octane tables are necessary... just guessing
