GAP tool live values

[GregMilner]

Trundling down from Perth to Dunsborough today I plugged the GAP tool in, out of curiosity. Couple of questions for those who are familiar with these gadgets.
1) attached is a screenshot, taken at 118kmh (indicated), 112kmh actual. Are these figures relatively normal? Ambient temperature about 25c.
2) what are the most useful live values to have on display on a long trip? I tend to concentrate on coolant temp, oil temp, fuel pressure and transmission oil temp, but are there others worth keeping an eye on?

I’ve only monitored sump oil temp and haven’t seen the other measure. Interesting.

Always difficult to know what some of these things really mean when the exact location of the sensor is not known at the same time.

Yeah, temps are all normal. My sump oil often sits around 100-105 at speed.
Can't comment on fuel rail pressure.
