Tuning Greddy Profec B Spec II boost controller

[Salar]

Hey guys,

Just wondering who else is running a profec B boost controller on this board? I have some problems tuning mine on my 92 GTS-T. Would be great to get some help.

It is a pain to figure out the functions on this unit. The manual is not much help.

I will post my current set up numbers. Will write them down from the car today.
I'm looking to see what numbers others are running.

Thx

i have one too, its a little complicated for me too. might just sell it lol get something more user friendly

I haven't used mine in ages. I found it didn't seem overly complicated as long as you're only really using the high & low settings and not playing with it for every situation.

These may help you:

i set up mine a few days ago and car is pretty decent now

here are the numbers (car is r32 gts-t with RB20)

Set 57%
Gain 20%
Set Gain 120 (12 psi)
Warning 137
Warning Low 0%

[nick-nismo]

turn that warning low up some percent, as if boost exceeds the warning threshold, it will reduce by whatever percent is in the "warning low"

[amnash]

so if its 0% it wont reduce boost at all? or will is reduce it to 0% (wastegate pressure)?

I'm also running it. Have no clue what my settings were and the car has been without a battery for nearly a year. I'm sure it has lost its settings. :/ I can't even remember how to even use it. P

yeah it won't. which is ok with me as it doesn't have boost spike. 1 or 2% might be enough in case it does spike and goes over the limit.
