Correct Boost Reading - Profec B 2

[GTR_Legend]

All,

Purchased and installed a profec b 2 on the weekend, works great.

Just wondering if anyone has had an issue with it reading/displaying the PSI?

Only left it and 0 duty and it displays .40 and creeps to .60 when i get to the high rpm's but it feels like more than that!

Anyone else had this?

I have the solenoid connected to the actuator and IC piping after the cooler!

cheers,

i have hks ebcIV and my boost gauge is way different to digital display

.8 bar on hks is like 15-16 psi on gauge

Mine is in PSI mode, so shows 0.60 x100 KPA as 6 psi, i think!!!!

[GTR_Legend]

doh, just relised that x 100 % KPA being displayed isn't PSI.

May help! Will check it tonight!

this makes no sense at all

either the guage is wrong or the controller is

0.80 bar is somewhere near 11psi and 15psi is no where near 11psi

i also have the Profec B spec II, the PSI reading is shown with no decimal point, so at idle it should show -90

Hitman explained it to me, Bloody Japs confuse us all

yep sorted

Still needs a good tune but damn she pulls hard on 10 psi, woohoo

do you have your boost gauge hooked up to where the boost contoller is? if it is in different spot then that can sometimes cause a different reading.

the ideal place for a boost gauge is between the turbo and the intercooler, because then you know exactly what the turbo is doing. if you have it after the cooler then you don't know exactly what boost the turbo is running, as you don't know how much air the cooler is restricting, you have to take into account the different density of cooler air, etc. some of the hks turbos come out with the wastegate hose coming straight off the compressor housing.

What is the most common setup? After the cooler?

[mad082]

from stock they come with it on the 'cold' pipe (cooler to throttle body). when i did my front mount install i had it off the bov hose and i found boost was all over the place (manual boost contoller). then i took the old nipple off the stock cold pipe and attached it to the hot pipe. this made boost much more stable.
