I use ScangaugeII for the past 8 years amd monitor all the required elements for the 6.0L Ford diesel.
On the Ford It's a must. Additional gauge required is the fuel pressure gauge. For Ford the oil temperature is very important.
Programmed with Hypertech for 8 years and it rocks and protects my engine. Cannot trust Ford for what they did to that engine. Also great code reader.
