2006 Mack CXN613, ecm report questions

The report doesn't show a lot - at all.
I suspect the fuel mileage reading is an estimate at the time of the 'snapshot' , (idling, sitting in a shop)- do you have more pages in the report showing max rpm, idle time etc?

 

That seems to be a generic 'read only' ECM reader. I've seen a Detroit report and a Cummins - 6 or 7 pages giving critical faults, and exact times/temps/speed/rpm at which they occurred. RPM and speed ranges with graphs, time spent at cruise, hard braking events - I mean a GOOD history on how the engine was operated.

I doubt the dealer is hiding anything, just doesn't have the necessary software to pull the report. Have you tried a Mack engine shop/dealer ?

 

That is just a snapshot of the engine's state at that exact moment. There is no history there at all. For that sort of thing, you're going to need a Mack dealer, or someone who's got the Mack software to talk to it.

 

This is a summary, an ECM dump is at least 6 pages long and details all of engine options and the operational data. I second the need to go to the dealer and have them to an ECM dump.

 

Looks pretty decent. I drove one very similar with a 427 and 9-spd, at a previous gig. Hate the fender mirrors though, it seems like the fasteners always rust and streak the white paint. My opinion on the 10-spd auto is not nearly so favorable. Early autoshifts were pretty well crap by all accounts.
