Hello Mick,

It looks like the baro and MAP are reported from the same sensor?

The captures are from a GM and this one is from a Ford.

It looks like the baro is reporting low for your elevation :-?

The Baro hadn't updated to the correct elevation yet is what I am thinking, but as I said I will check Monday.

158Hz is correct for around here on a normal day.

This is a Mazda Protege 2.0L it has an EGR boost sensor which I believe acts as a baro sensor, I will have to look it up on Monday.
