Hey guys, I have a hks evc installed in my car (control unit has power), but the stepping motor Vac line/pressure lines are disconnected... so i had a go fitting the lines under the hood and i couldn't get it working..

is this right? Sorry for crappy drawing... just a quick 1 min job :P

It's a HKS EVC EZ II, it looks exactly like a EVC 5 but without the LCD screen unit ( the EZ II doesn't come with one)

I have the Control unit in cabin with A/B knobs which has power, and the stepping motor under the hood.

Ok what works is the control unit, i push the A/B buttons out, turn and set the boost to whatever, push the knobs back in and they save, the stepping motor is not doing it's job because no matter what i set the knobs at the car runs 7psi on both A/B settings.... So this made me think iv hooked up the vac lines wrong or the stepping motor is stuffed..

Pics up soon..

nope :( didn't work.

on another note, Zebra that pdf is for the EZ 1. I have the EZ II.

I think my pressure source hose could be wrong... what do yous think? disconnect from carbon cannistor and connect to fuel pressure line?

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
