Apexi optional boost control kit..HELP!!! - Page 2 - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Now I just have to figure out why my fucking control kit started spazzing out. Now its either not controlling boost or itll spike up to 2.2 bar.

you got the numbers on the boost controller screen all messed up (to high of to low)

read this site it tells you how to set it: Apexi PowerFC FAQ

bring this thread back. I stand corrected, boost controller issue still not fix. Boost up to 1.15 bar but no more, no matter how high i set the duty cycle. I guess i need the stock boost solenoid plug.

I will, as soon as i can figure it out after some new test. After soldering up and piggy backing the boost valve to the map sensor power and ground, it holds boost up to 1.15 bar only.

Ok, so the problem. No matter how high i set the boost duty cycle setting to (first 30, now 86), it still wont boost any different! All i can get is 1.15 bar, and thats just sometimes. The only difference, it boost up faster than just running off the actuator and does not boost boost pass 1.15 bar, even tho i have the boost setting set to 1.25 bar.

Quick question to people that are ABLE to run the boost controller, what is your boost duty cycle value set at? Ill post pics tomorrow about what i did and such tomorrow on piggy backing the valve off the map sensor.

Damn, double post. Is it just my computer connection or is it the website that is a bit slow?

***S14DB*** · 01-10-2010, 11:30 PM

What turbo are you trying to get upto 1.25bar?

bl3ujay07 · 01-10-2010, 11:50 PM

I am running a gt2871r. Boost needs to go up when i am at the track.

This is a common issue with the integrated boost solenoid kit on many EMS.

Espeically with the internal wg. If you have an internal WG with an adjustable arm then I would try to tighten the arm so it's shorter and pre-loaded more. This will force the wg to hold tighter towards the beginnig of rolling into boost.

Otherwise you might want to look into other more serious dual solenoid type 3rd party boost controllers.
