Holley HP EFI Data Logs

I am in particular looking for any data log records when going from idle to on plane and/or throttle down from WOT or high speed down to idle. At this point any in boat data logs with knock levels record of a similar BBC type engine on water running would be of interest. I am interested in what may be the differences or similarities of other in boat engine knock level characteristics.

Its the knock vs false knock issue. My engine (in the boat) is very noisy requiring sensitivity setting down to 35% just to get by. Then 100% knock levels show up where they should not be. I need to see what a different BBC engine/boat knock level looks like for comparison along with all the other data logged parameters.

Are you running your rockers on the loose side? Maybe when the RPMs come down enough after having the lifters pumped up, the decreased oil pressure is allowing some momentary clatter and you are picking that up.
