Hello,  I am working with a 7747 and the esc module does not seem to  
hear the knock sensor or when it does it is at the wrong MAP/RPM. I  
installed a knock sensor in the side of the block at the coolant  
drain. When I tow with the truck I get a lot of pinging/ 
predetonation. During one drive these pings were recorded correctly  
at there respective RPM/MAP positions. But since that time they show  
up at the edges of the  WINALDL map while datalogging. By that I mean  
they are in the 400 RPM or the 1000 MAP rows and columns. I replaced  
one ESC module as it was faulty and the situation improved however  
the pinging and incorrect data values continue, Any suggestions?
