Greetings,


Just want to know if the power FC is accurate to mesure
the boost on my FD. I have a HKS AVCR and the boost
reading is not same as my PFC.

Thanks

Serge

 

man you know what I have a boost gauge, PFC commander, and the boost computer HKS evc pro.
NONE of them match... Now it I turn on my turbo
timer, it matches with the EVC... I asked this, and
most of the mechs say the PFC is the most acurate,
the EVC and all the rest of them jet their imputs from
the computer so trust that... Mine are only off a butt
hair... BUT thats what they say....

Hope that helps

 

the stock boost sensor can only measure up to about 17psi correctly.

 

Remeber the variables involved. My Apexi AVCR is taking a boost reading from a teed line between the upper intake manifold and the IC pipe right after the turbo. That right there is going to make the readings different from the stock sensor. Also, how long a hose run to the pressure sensor for your AVCR? That will effect the reading a little. Boost measured pre-IC will be different than boost measured post-IC, etc, etc. So, little variations don't mean anything's inaccurate, it just means the samples you're taking are effected by all these variables.

Since the AVCR is the one actually controlling boost, you should probably use that as your accurate measurement. Whichever you choose to use as your reference point, stick with it. Don't tune for a certain psi on your AVCR, then go turning up the boost because the stock sensor (PFC) says the boost is lower than you tuned for, for instance. Pick one and be consistant.
