Engine knock

[ktl]

So got myself some DIY det cans and i can hear ever so slight knock at 1.4bar. Is there a certain amount the engine can take ?

Every bit of knock is doing damage, either to the piston crown or the big ends. Rule of thumb is, when you hear knock, take 2 degrees of timing out.

Could i do this with the dizzy or would i have to alter it on the emanage ultimate ?

It would be easier for me to do it on the dizzy and timing gun (snap on)

You would be better off changing the settings on the emanage.

And would this effect the whole fueling map ?
