whats the best way to limit knock on hot start? 2013 camaro ls3 m6. right now being a dead stock motor with stock timings and only ever using 91 octane, on hot starts it can sometimes knock once or even 3-5 times quickly in a row. increasing the flare control and retarding start up timing doesnt really do anything either. in the same vein id also like to tame down startup flare (so its a smooth start not an aggressive surge) as much as possible, without compromising its reliability to actually start of course. the adjustments ive made above to combat knock have definitely made it more mild but i want to take it as far as possible for a super stealth startup. no real reason to do this though, i just like it.
