First time logging on evo 5 stock map as far as we know, aem uego installed and logging through ecu pin 75 we are still trying to get the log to match gauge but on boost looking at gauge afr is fine. Getting knock on all 3 pulls from 5k and 5 "1" counts. Im confused if that means 5 counts of knock or 1 count.

That's nothing to really worry about. Knock has a delay timer. So when the ECU thinks it's got some knock it takes a bit of time for the knock to go back to zero.

What you're getting is 1 count of knock. That's not much. You should get worried when you see 3 counts of knock especially if it's consistent. Since you say that you're seeing the single count of knock everytime, it wouldn't hurt to pull one degree of timing and see if it goes away.

IIRC, 3 counts of knock = 1 degree of timing pulled.
