make sure you hook up the solenoid correctly, for integral/internal and external/poppet wastegateSo here is the issue, just fixed the engine completely, and ripped off the funny manual boost controller/bleeder/lowes brass needle valve/whatever it was and installed a nice electronic boost controller and its having some issues.
When its hooked up, it is incorrectly reading vacuum pressure, my boost gauge says 20 psi of vacuum, but the ebc says 604. And when we tried to do test passes to calibrate the ebc, it never calibrated and the boost was around 15 psi.
When we bypass the ebc and hook up the hoses from compressor side to the actuator, it will hold nicely at about 10 psi.
Anyone have this problem before? We out ruled the boost leak, because it holds 10psi (basically stock) fine, but when we hook it up, it jumps to 15psi and we havent even set boost on the ebc, and are un-able to get the ebc to function corretly, it is brand new too, does this sound like a possible faulty stutter box?
Any suggestions appreciated, thanks in advance.

Problems with HKS EVC 4?

It is set correctly, I wish it was that it wasnt, lol.make sure you hook up the solenoid correctly, for integral/internal and external/poppet wastegate
where does it reference boost/vac from?
The vacuum tree. I split the tube that feeds into the stock boost gauge meter, and ran it off that, because I have an autometer boost gauge that feeds from the intake manifold, I was thinking of switching those, but my friend has the exact same car with the exact same EVC 4 and thats the way he does it and it runs totally fine.where does it reference boost/vac from?
pinch in the line somewhere maybe?
We inspected each line, they all were fine. All were sucking, lol.
hey ill buy that shitty mbc u have that u ripped off the car
Gave it away to a friend.hey ill buy that [shizzle]ty mbc u have that u ripped off the car
Still no luck with setting up the EVC, tried to calibrate it and adjust it last night, put it in a different location, cleaned all the connectors, still nothing, still isnt reading correctly nor adjusting boost correctly, put it at "stock boost setting" with .5 bar so around 7.45 or so psi, it shot up to 16psi, reading from my autometer boost gauge, the gauge on the EVC doesnt even display that correct. Still does a weird function to where it will show what the vacuum should be (when I disconnect the harness) then when I reconnect it (it shoots up to an un-believable 600 vs 200 normal vacuum).
Faulty box maybe. Can you exchange it for another one?
Unfortunately no.
But I did clean out the stepping motor and something fell out, so I re-assembled it and now it is at least reading correctly, still a problem with it reading my stock boost and being able to run low boost, the lowest it will go is about 18-20psi.

My above post was decently correct, but there was a boost leak, and I fixed both those hoping it would fix my boost controller problem, but it only made things more confusing.
Hmm...
When I run the stock setup, the boost holds nicely at 10 psi boost, DUH stock...
But when I hook the evc up, it boosts up to 20 psi, scary, but then I was like ok ok, it was after all in "learning mode".
BUT, after it completed that, it assumed my stock boost is 18psi. So I cant run it lower (and even when I manual set it to 10psi for a stock setting, it wouldnt even hold it at that, when it was on it would still shoot to 20psi).
So I have ruled out everything mechanically, either its a faulty stepping motor, head unit, or I set it up wrong, yet I followed the directions down to a T on the manual.
Am I the only one having a bad experience setting this up, or does this not sound right? From what I have heard most people plug theirs in, learning mode, bam ready to go, and learning mode wont go over the stock boost setting, mine, seems to keep the wastegate closed till about 18-20psi, but when I run just a tube from the compressor side to the actuator, it opens at 10psi ruling out a faulty wastegate.
:shrug:

I am very bored at work today, so I decided to draw up what exactly is going on with my problem, maybe showing it will help more instead of reading it, but last night I even tried to calibrate the evc, and right when I thought I had it, I was wrong, it went up to 20psi on a freeway pull.
But here is the picture, with 3 different senarios I tried and what exactly was being read boost/vacuum wise (which the evc reading shows at least that part is working)

sounds like a faulty unit (the little box you drew hks on). if you just unplug the wastegate all together you usually get about 20psi on these turbos anywho due to inefficiency.
bummer... but thats pretty much exactly what i needed to hear.if you just unplug the wastegate all together you usually get about 20psi on these turbos anywho due to inefficiency.
maybe you have the bleed nipple confused. try hooking up the hoses to the other nipples (on the hks box only)

how is it a faulty unit, in the 2nd sceneria the wastegate is basically acting as a boost gauge since the solenoid is not hook up.
so make sure the integra (no/nc) is connected correctly. because if you have internal/integral wastegate and the wrong port is connected, it will read it as external thats why most solenoid comes with 3 ports or more. read the manual again and take your time reinstalling it.
the faulty unit was a guess, i dont know shit about these things :lol:
its a bad wg once i swap ot out everything will work
