I'm getting ready to install my Edge Insight tomorrow and was looking through the manual tonight. There is a Dodge specific parameter in the Air group called "Trk Turbo In" which is supposed to be "Truck turbocharger compressor input temperature". Is this then the same as a standard before the turbo EGT measurement? Edge is back-ordered on their EGT probes but do I need one?

 

Never mind. Seems the turbo inlet temp may be a Chrysler specific PID, but its not specific to the 08 3500! I'll just wait for the EGT probe to show up...

 

No "Trk Turbo In" should be just after the air filter before turbo and engine. EGT is after the engine before the turbo. EGT is Exhaust Gas Temperature, that "Turbo in" would be just the temp of the outside air being used by the engine.
