safc2 as a boost gauge

**nwr31** · 17-11-2009, 08:21 PM

anyone know if when using a safc2 to display intake manifold pressure (as in pic) can it actually display positive pressure & not just negative?

have checked manual but no luck

thanks

No mate and its is SO not accurate as far as real time goes, and very hard to make out . Imo, better off with a decent needle guage or digital readout, like a Profec B 2 or Eboost . Much easier to follow .

yeah i dont actually use that mode - most of the time its on the 4 channel/straight digital read out which seems accurate, displays boost pressure & has the very handy peak hold feature.

why i wanted to know this was because when i use the scrolling graph for boost (it has no scale on the y axis) i had a feeling it was displaying like the one above... ie, only a vac gauge :|

which is a bit of a shame because i thought i might have been able to use that scrolling graph to check/compare the boost curve with different mbc's im trying.

hope i made it clear enough & thanks for the reply

cheers

this is how i use it for a boost gauge most of the time, the scrolling display is what i wanted to use for testing boost curves.

in the setting its asks how much prs(pressure) to show, in bar, so you can set it to 0 (up to 0 vac/psi) or 1 bar 1.5 bar or 2bar!

but i just use the display that NWR31 posted!!

very handy, shows RPM, PRS, THR, VOLT, o2, KAR, AFM all sorts o stuff!

just buy a boost gauge.. it would cost you more then 50 for 2nd hand jap brand..

but the safc have play back mode.. which is awesome! for time to time

thanks, will try to find that setting.

but the thing i dont get is why it displays vac & boost fine in digital readout mode now, but not for the scrolling display (& the gauge display above)?

cheers
