Yes, you can!
For the GT
With the GT Tuner you can with the following vehicles, since they have factory sensors we can read:
08+ Ford Powerstrokes Diesels
07.5+ Dodge Cummins Diesels
07.5+ Duramax Diesels
If you wish to read your EGT's on the older diesel engines you will need to purchase our Sensor Docking Station with Pyrometer. Click here to see this product in our online store.
For the X4, LWTS+, BDX and GTX
If you have a 2008-2010 F-Series SuperDuty 6.4L then you can monitor your EGT's directly from the ECU while connected to one of those devices.
All other vehicles will require our 9817 EGT kit to monitor your EGT's. Click Here to see this product in our online store.
