knock sensors sensitivity

[dat111]

hey guys, 

being having a chat with a mate, 
the knock sensor sensitivity, it says higher numbers are more sensitivity
ive also read on the forum that its opposite way around lesser numbers are more sensitivity 
so which is which 

**just for comparison** 
NA sensors (on the left) are higher then F6 (on the right) 
an then the lower right hand is a tune i had touched up for me by a local tuner. 
an then (not pictured) the knock sensors 
(stand alone photo is me just messing around)

Lower is less sensitive.

Imo you can lower them by 20% and be fine. If you lower them by 30% you will crack a piston.

Don't take my word for it tho, get some knock ears and work it out yourself. Tuning a stock motor and specifically the knock maps without knock ears is asking for trouble.

hey puff wagon, do you have any information on what the "auto octane/91" calibrations do?

auto octane switch 0/1 (was 1/1
91 octane was 0/0 now its 1/0
(i think i may have turned off the auto octane, an turned on the 91 octane -.- LOL!

Not really. I know a little about it but not enough to give a definitive answer.

Compare it to stock to see what it was originally.
