Product Detail
This part number does NOT include the Pyrometer Connection for reading Exhaust Gas Temperatures.

The Pyrometer connection is NOT necessary for the Black Maxx to function correctly. It is used for gauge display and for one of the defueling parameters. It will NOT harm your truck to run without a pyrometer probe installed. We do, of course, recommend purchasing one for the 6.7 Cummins and 6.6 LMM Duramax so you can monitor your Exhaust gas temperatures and set your defuel levels based on EGTs. Ford 6.4 Powerstroke trucks will use a factory sensor in the manifold to monitor EGT. Click HERE to purchase a Mini Maxx with a Pyrometer assembly.
