[spooled240]

this is a newb question but here it goes im building a ka-t and i heard that stock ka's have knock sensors...is that true? and if it is does it retard the timing if the engine pings? any info would be great thanks

Yes it has a knock sensor. For your safety, no it will not retard timing if it sees knock. Its a little more complicated than that. It runs a Knock map which is basically a bunch of overly safe timing and fuel maps.

so do you think i should get an aftermarket knock sensor setup?

I'm pretty sure the it works is, when the DE ECU detects knock it automatically switches over to limp mode so you don't damage your engine?
