I would like a device that attaches to the diagnostic link when desired and can tell me the same type of information that most people buy guages for: egt, fuel pressure, boost pressure, etc. No need for performance enhancement, just want to see what's going on from time to time. Does anyone know if such a device exists?

 

Nope. The only one of those parameters that the computer monitors is boost pressure.

 

the new quadzilla monitor is stand alone and does egt,boost,fuel press, trans temp, etc.

You go get a Road Relay from Cummins.

I know that it will work on my 02 (I looked into it) but not sure about the 3rd Gens

won't work on the 3rd gens, they use a dodge only communication protocol that the road relay can't read.

 

Quadzilla Commander monitor. Will be avail very shortly with all whistles & bells
