hks evc3 - cant set below 0.74 bar?

[paulr33]

hey all,

i just installed my hks evc3 :aroused: and gave it a fang and it seems ive got the some problemo's

- can't see boost below 0.74 bar

when in setting mode, im unable to scroll below 0.74 bar for some strange reason. not that i mind but i want to make sure the plumbing and everything is correct because no matter the car goes to about 9psi regardless, even if i set the boost to 0.90 bar its still about 9psi. on the stock solenoid it would run at 5psi then 7psi so it doesn't seem (well i think) that its got a different wastegate spring ?

- turning unit off does nothing

in the sense my boost does get set less or more

i mean by going from green to red mode and also cutting power to the unit

- unit doesnt show current boost level

this is because i haven't plumbed it in the manifold (will fix later)

well at least my understanding of it is, corrections anyone?

If I go boost set, and choose low mode its on 0.74 bar then if I goto high and set it to 0.90 not much happens really. It still seems to the go the same.

Has anyone seen this before? Port 1 goes to intercooler pipe, Port 2 goes to actuator and port 3 goes no where (soon to be fixed). The car feels to pull more and certaintly responds better so the boost feels like its there. I am using the stock guage so its probably out of whack but I should still be able to set the unit below 0.74 bar shouldnt I ?

I've checked manual, google, forum search and wiring plumbing

I still have stock intercooler and exhaust (soon to be changed)

Any ideas would be great thanks

fear not, i have indentified one issue. the scan of the hks evc 3 manual i have is blurry and the numbers on the solenoid don't go in order

They go:

2 3 1

I thought it was:

1 2 3

1=intercooler 2=actuator 3=manifold pressure sensor

Will correct tomorrow, this should correct set 0.90 not working

Any ideas re: cant see any lower than 0.74 ?

[GTR-Ben]

Maybe .74 is the lowest the wastegate will allow?

it is the minimium or stock boost of your car and the unit wont let you run lower boost than your stock boost.

on mine i had it set to .60 bar and .75 bar when i was running the stock turbo

was already set like that when i had the car tho

if i had my manual for it here i could tell u how to do it but my mate has it atm

[paulr33]

i fixed the incorrect plumbing and the display now shows how much boost

however no matter what i set it wont boost over .045bar no matter how hard i try

ill do a full reset and get it to do its self learning evc mode and see if that helps

[paulr33]

okay tried full reset and i cant even start the learning mode

it displays the '3" and its waiting, the manual says take off in 3rd and rev out until it beeps. the unit never beeps and i cant get out. awesome. double checked piping and tried it the other way around, 5psi non stop and just keeps displaying "3"

Maby the wastegate spring is stuffed ?

Is it external or internal gate ?

[KamikazeR33]

it wouldnt be the wastegate spring

if anything the solenoid could be broken

ill get my manual and take a look and let u know what i think could b wrong

[KamikazeR33]

just as a question tho

when ur setting it is it on the first or second mode, being a dual stage controller and all
