Default My SECS Monitor shows my MAP -0.9 when the engines off?

As title - is this normal? Anyone else with a secs show different? Bad earth to map sensor?

I also have a SPA boost gauge and the SECS guage are off by like 3.5-4 psi at full boost (like 26 psi).

Anyone else have a difference in boost gauge to ecu monitor?

Yeah, I have a 3 bar also. Does your boost gauge show a higher boost than the ecu monitor too?

Something to do with air pressure, dependent on height above sea level IIRC???

My SPA boost gauge reads 0.0, so don't think it's that.

exactly.

manifold ABSOLUTE pressure - not gauge pressure, a so a gauge will read 0 when the absolute pressure may be slightly above or below 1 bar absolute at different atmospheric conditions
