    Wastegate adjustment thread

    Hey guys, I worked with tork the past few months with an issue I was having with boost. I spent tons of money part slapping, but tork gave one suggestion and it solved all the issues I had. Issues: BOV opening prematurely, 22mpg, barely and rarely hit 20 psi when with the tune was supposed to be 22 psi, engine light and codes including insufficient boost-over boost-P1111 and wastegate getting stuck open.
    Procedure break down:
    Tools: 10mm wrench (I used a ratchet wrench)
    Ramps or Jack stands/jack
    Flashlight
    Possibly a 14mm (I think it's 14mm...I'll explain)

    Step 1: For God's sake, let the car cool, you will be sticking your hand and arm is hot places.
    Step 2: get car up on ramps or stands
    Step 3: there is a turbo bracket with 3 TIGHT bolts. I didn't remove this as I was able to sneak my arm up around Okay.
    Step 4: locate the wastegate adjuster (I have pics, will try to add them)
    Step 5: there's a 10mm nut on both sides of a black cube that has the rod through it. Loosen the nut on the left (drivers side). The nut on the right of the cube will now be loose. Spin the nut by hand to the passengers side until you run out of threads.
    Step 5: now, tighten the nut on the left until the square cube goes to the right nut. Tighten the left nut down.
    Step 6: if you took the turbo bracket off, put it back on
    Step 7: lower car
    Step 8: start car, listen for anything odd (just for safety)
    Step 9: unhook battery to reset ecu
    Step 10: hook battery up and enjoy

    All the issues I listed above have been solved.

    So what you basically did was to adjust the wastegate such way it will open later. You compressed the spring not allowing for it to open.

    BOV will have to work more for it then.

    Let us know after a while if it helps at all.

    P.S.
    Man, you must do something about the way you attach pics. It is impossible to view the post.

    I remember having to do this on my Optima when the weather changed...

    You should have listed this as a DIY and asked a mod to stickie it!

    But does it do anything? BOV will adjust anyway. Compressing the spring will only delay when the wastegate discharges boost.

    If you wastegate voltage is off you can go into limp mode or the vehicle wont run optimally. Before making the adjustment on my Optima at cold start I would have ZERO turbo, turn the car off and back on and it would work fine. Voltage was off (it has something to do with the cold I think) and had it adjusted back to spec and the car worked great again.

    If this is off I dont recall a code being thrown but I could be wrong.

    You can read the voltage while you adjust, anyone know the specs on the 1.6T for what the EWG voltage is supposed to be?

    This is what I'm talking about from the OptimaForums:

    Yes, exactly what I read. Wastegate is controlled and sends voltage to say how much it is closed/open (however you call it). You can adjust it a bit (+ or -), but cranking it all they way up - I am not sure that's the solution.
    I do not know what the voltage should be. I have a feeling mine is a bit off, but I will not deal with it as KIA made some marks on the actuator and if they are off - well, warranty claim might be a problem.

    These little 1.6T do not have the EWG like the Optima. These are controlled with pressure from the compressor side of the turbo which is cycled with a solenoid (located at the left side of the crank pulley).
    Default pressure for the wastegate to open is 12 psi, making this adjustment allowed the default to be 14 psi (on mine).

    I did this on mine and it helped big time. I do notice at lower rpm the bov goes off a tad more but it pulls way better. Now with my new tune from Tork she is a freaking beast!
