Martin,just downloaded the pc program,will be using it on the laptop in a 98 WesternStar with a 60 series DDEC4 I will play around with it to see if i can monitor everything i need and then will be ordering the hardware to hook up to the truck. One thing i do see missing is Air Pressure readings,but these don`t go thru the ECM. Wonder if a guy could use something similar to the tire press senders to get these. All trucks with air brakes have a primary and secondary system,plus air brake application.Mine also has Trailer supply. Kind of suprised to see these mising as all coaches with air brakes would have these too.
