SECTION 2: INSTALLING THE OPTIONAL PYROMETER AND THE PYROMETER CONNECTION
HEAD PCH
* The Pyrometer and PCH are optional and some vehicles will not require them. Your
vehicle may have a factory solution for reading Exhaust Gas Temperatures.
In this section you will drill and tap the Pyrometer Probe in the exhaust, either pre-turbo or post-
turbo as a means to collect exhaust gas temperatures (EGT). Exhaust gas temperatures indicate
how hot the motor is getting and can be used to set safety defueling parameters.
POSTTURBO VS. PRETURBO
You must decide between mounting the Pyro Probe either post-turbo or pre-turbo. The dierence in
location determines what temperatures will read on your Mini Maxx. Pre-turbo mounting is gener-
ally recommended because it provides more accurate EGT readings.
The Mini Maxx is capable of running two pyrometers simultaneously. Please purchase an extra probe
if you wish to read pre AND post turbo pyrometers.
