Knock

[MorsusMihi]

What is an Acceptable level of knock, I tried to use one of the hondata preload tunes for the factory settings one, and while on that tune my car seems to knock a shit load and under minimal throttle

Also, with that tune supposed to being close to factory settings with nothing changed, when i jump on the throttle the A/F drops to like 10, i feel this is far to low and will end up melting pistons

has anyone else experienced with the base factory settings tune or the hondata reflash tune supplied by the flashpro manager??

Looks normal - knock control is a better indication that knock count. I would disable the 'fuel economy alternator control' under misc for all 9th gen si vehicles.

isnt it odd that i had 6 knocks and it wasnt even under hard accelleration?

What does the fuel econ alternator do in 9th gens

Kills your battery by running the alternator at 12.5V rather than 14V.

i have another log for you, this time it has 10 knocks in a shorter time frame,

Is it normal for the hondata reflash or the stock equivalent to knock this much
