hey guys anybody help me with what settings i should run on my boost controller
I'm running the singal Turbonetics Kit on my 2003 350Z touring with the
GReddy PRofec B-specII
just need to know the

SETTING FOR

Boost Mode
SET
GAIN
STARTING BOOST
WARNING
LIMITER
PEAK
I only wanna push 8 or 8.5 pounds of boost right now until i get some more add-ons. I'm running the Factory Settings on the controller right now and it keeps spikeing to 15

Anybody body help>>?

or a quick how to on how this controller works

 

its all different for each car best bet is to start a zero and build up.

 

what if i'm wanting to run just like stock setting for the turbo

 

dont hook up the boost controller and adjust your waste gate.

 

just put the timer and the controller on last night

 

Anybody use this controller

 

yeah ive used it plenty. You have to read the instructions to understand i could throw out numbers and they may be right or completely opposite.

 

what does the car boost when the controller isnt hooked up? What are your current settings for set and gain.

 

just set the gain to around 10 and the set gain to 10 and raise up the boost level a little at a time.

its pretty easy to learn how to use. do a search and read the nice write up on the evo forums to understand it more...

 

to 10? doesnt it go all the way to 100? i have my gain set at 69. it does spike a little sometimes but thats only if im in 6th and punch it while i'm going slow it puts a lot of load on the car and it spikes .5-1 psi above what it is set at. is mine set to high?

 

if you have the TN kit, have you downgraded the spring on the wastegate? The standard spring is 9lb on the TN kit so the controller won't work until you go past 9psi. You do loose a little through the intercooler, so even though the wastegate opens at 9 (pressure at the compressor), you will get cut off around 8.5 (pressure at the manifold). The controller will alow you to reach 9 or greater at the manifold, but if you are aiming for 8 you need to change your wastegate spring to 6lbs and then set the controller for 8psi. I do realize you asked about gain, but I wanted to make sure you weren't wasting your time.

Since I have a stock engine, I only have the boost controller (profec B spec II) hooked up to the manifold pressure (the controlling solenoid isn't even installed). I'm using it as a second gauge, the problem is it is only showing 50% of what my gauge is showing. They T off the same line and are only about a foot apart. The gauge seems to be correct, so my only guess is that my line to the controller is kinked. (i have the controller turned off, but it still displays pressure, in psi X100) at idle ~-20psi on the gauge shows up as -100 on the controller (should be -200), whats up with that?

 

was safe to run on the stock motor?

 

Link? Im lazy today . . .

Spring Pressure!

 

The standard TN kit comes with the evolution wastegate, with a 9psi spring installed. This is designed to limit the power to levels safe for our stock engines <400whp.

However, safe is different for everyone, it depends on how you drive. If you are redlining, dumping the clutch, and racing alot, your engine will not last even if you only have 300hp. I have the TN kit, on my G35 with 70k miles, so even if I drive nicely, it may not last as long even though its at "safe" hp and psi levels.

 

The available springs are as follows:
Each spring has a colored stripe on them.
30778-5 BLUE
30778-7 WHITE
30778-9 RED

The springs retail at $26.39 each
