Hey Guys,

While driving or idleing, open or closed loop, my knock counts start low and count up to about 250 and then start over. I also unplugged my KS and it still counts up.... I'm running a 7747 and datalogging with TunerproRT. Has anyone seen this or know what could cause this? Maybe a bad ESC Module? I'll attach my latest 2 datalogs so you can see what I mean. The first one is during drive in closed loop. Second one is open loop, cold engine in the driveway idling.

Also I don't think it is from exaust rattle or anything on the truck rattling because wouldn't it be constant?

Thanks in advance!

 

not sure about your ecm but for the 730/749/727's it normally turns out to be the memcal isn't seated right or just bad.
