Im getting some pretty good knock and wanted to have someone take a look at the logs.
Ive been told some things and i wanted to get the experts or someone that knows more than i do.

Regular Stage 2 was knocking worse so i flashed the ACN map to see if that made a difference and had a full tank base gas station.

Thank in advance.

 

^To piggy back on that - what is normal knock and not normal? Also what does acn stand for?

 

i tried to post the Data-logs but it wont accept .csv files


to answer your question ACN is the title to one of Cobbs maps 91 octane fuel from Arizona, California, or Nevada


Ok there its loaded as a zip. There are two data-logs same day within a few minutes of each other.

 

How much knock are you getting? #'s

 

Its a little harder to tell true knock on the SSTs.

The first datalog looks ok and you can tell that its correcting itself by pulling timing and reducing the knock count.

The second datalog looks weird though in the higher rpms where you're getting 6 and 7 counts continuously. Was the road bumpy? Anything that would have caused extra noise or vibration?
