Not all engines have the differential pressure value available for reading.

CAYC engine in particular has many different configurations due to its various firmware versions. The engine I tested months ago didn't have that value in the engine parameters list, but some users report me the existence of differential pressure data using other diagnostic testers, so I have to investigate more deeply.

That's how it looks unconnected to the obd.
When I connect it, the pressure parameter disappears.
Strange.

It's normal: before connecting, the app doesn't know your engine code so the default setup is for the engine group 0 that has the differential pressure.
After connecting, the app recognize your engine and changes the engine group to the number 6 that doesn't have the differential pressure.

Unfortunately, not all engines have the differential pressure parameter available for diagnostic reading.

The CAYC engine I've tested in the past didn't have it.

I need to make a scan with my instruments to learn the correct request for the ECU. I hope to do it in the future when I'll have a CAYC engine available to be tested.
