I've done a search here and on other sites und I haven't found the answer. What are the roughness monitors for the cylinders? Is this knock. I have cobb Stage1 with short ram intake, and when I lift after wot I see it. I don't see it under load only when I lift. Cylinder 4 has the most at 3. log below. knock correction valus between 0 and 5.5 across range. kock sinal (digital) is 0 across below log.

Hi Guys,

Scott (SOG) got back to me about this via PM, here was his response, in case somewhere else gets it..

-----------------------------

The "roughness" monitors are actually from the front air fuel ratio sensor that can tell by crank position if a cylinder "misfires." If it's only on lift throttle don't worry about it. This is what can set off the misfire CEL though...
