Does the Edge Comp leave a footprint on the ECM? I'll be finding out for sure tomorrow, if nobody knows. I thought they did but, I don't remember for sure so i'll just have to let my buddy at Cummins tell me.
From what I was told by a tech at Cummins, they can tell if any alterations were made to the ECM by the parameters being above/below the norm. That is just what I was told, so take that info with a grain of salt.
