I get 3-4 knock counts on a full run thru the gears. Is that ok or do I need to lower the timing from 4deg back to 0. I am using a Snap-on scanner to read this.

How much is the computer retarding for this? I am open to opinions.

 

with that low a knock count i doubt the ecm is really pulling anythng at all. that is good for a full run. leave the timing where it is.

later

3-4 is good, leave it alone.

 

thanks
