Help With Hks Evc

[Aleckr33]

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

what model evc? post a pic if you can

and when you say it doesnt work, what doesnt work

[Aleckr33]

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..

cut the boost signal into the fuel pressure reg line and remove from gray canistor line, otherwise the drawing is correct, i have evc 5 in my 32 and evc 6 in my 34, make sure the boost lines are connected to car correctly

Have a look at the PDF, it tells you how to run the lines

Edit - here is one for 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?
