i have a vafc…(duh) and a boost gauge. when im boosting my gauge says 5 psi. which is right for now until i get my boost controller. but my vafc only reads +0.20 at the most. is that right? i thought i can use my vafc as a boost gauge as well. am i wrong? please help thanks
vafc, isnt a boost gauge, its a tool to fake the ecu into putting in more fuel
or less fuel
well it measures the vacuum then when it starts boosting it goes positive just not what i expected. i understand its not a boost gauge but if it reads vacuum then why not boost
nevermind. it reads boost in bar. just so anyone else wanted to know
of course it does… it is a Japanese product and in japan it reads always in bar… so if it has to be one way or another it will be in bar… if it can be either then u can buy either…
what? i understood the begining. then you lost me
the vafc only reads vacuum not boost… mine read from -10psi at idle to +0.5 at full throttle
my vafc (on my n/a b16a) always read - press. even when i stomp the gas. Shouldn’t it level out at zero when i have it hammered??? I’m not sure but i think i remember another friends reading zero press. when he did.
:bump:
