boost gauge hookup

[1PhatCX]

just wondering if i can hook a boost gauge up to a vaccum line for the time being? and just wondering if its possible because i wanna have all my gauges installed and everything ran into the engine bay

yes. if your boost gauge also reads vacuum it can be a useful tool in tuning. the stock honda maps read vacuum/boost & rpm to determine the table location to read from, so you can tell whereabout in the table to edit by reading your vacuum (or boost) and rpm

of course you can!

awesome! yea the gauge reads vaccum too
so i can just pick any vaccum line and hook it up eh

yup, just T that boost gauge into a vacuum source, a good one would be the fuel pressure regulator hose.

dont T off the fuel pressure regulator hose. It can cause problems with delivering the correct fuel pressure because of low or incorrect vacuum on that particular line.

T off of the purge solenoid vacuum line located on the back side of the intake manifold
