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?

 

not normal but don't know why. mine reads zero with engine off

 

mine reads -0.8 what map sensor are you running 3bar ect

 

Mine reads -0.8 as well, it's running a 3bar

 

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

 

not to sure on the boost gauge but iam on a 3 bar as well it seems to be the norm then try secs they might be able to tell you the reason for this

 

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.

 

yeah but does the spa gauge read from the MAP sensor??

 

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

 

:takes a bow:

see I do know some things pmsl.....

 

You can forecast the weather with a SECS too
