Looking to monitor your EGTs with your BullyDog Watchdog or Triple Dog GT Tuner/Monitor? This is the kit you need to make it happen! This item works on the Triple Dog GT and Watchdog ONLY. It does not work on older discontinued tuners such as the PMT. This BullyDog Sensor Station and Pyrometer Probe Kit comes with everything seen here which includes all the parts and pieces necessary to acquire exhaust gas temperatures to display on the Bullydog Triple Dog GT, the Bully Dog Watch Dog, or the Bullydog PMT. Thermocouples, speed sensors, boost sensors & liquid temperature sensors can also be added to monitor even more on your Bullydog Tuner! This kit includes one pyrometer probe which will capture one temperature reading along the exhaust stream. This Pyrometer probe kit also includes the PCH board, as well as the electronic dock for the pyrometer probe. The Bully Dog devices that utilize this kit already have the programming ability to display the pyrometer temperature readings when you use this kit. Using this on a diesel truck? Heres an added benefit: Installing a Pyrometer Probe Kit along with a 40420 (diesel Triple Dog GT) unlocks the safety defueling feature for defueling based on exhaust gas temperatures. This kit offers the optional (not required) ability to monitor a 2nd pyrometer probe (sold separately for $44.99) simultaneously. The additional Pyrometer will hook right up with this kit and allow you to monitor EGTs at 2 different locations in the exhaust system at the same time. The part number for this item is 40384
