    HKS EVC EZ wiring diagram?

    I picked up an HKS EVC EZ for 50 bucks. A deal I couldn't pass up. So here is my question...

    Does anybody have a wiring and or vaccum line diagram for this boost controller. The guy I bought it from didn't have any of it so im kinda flying blind right now :/ I called HKS and their entire customer support line is down and practically doesn't exist.

    here is a pictures just to clarify the generation of the HKS EZ I have.



    Please and Thanks Guys!

    Well the only thing I am worried about is over boosting since there is no actual read out. So I will need to get a Boost gauge and Air fuel gauge to make sure all is well. Im looking to go with 13psi MAX.

    Any easy way to do this or just install EVC EZ, go full boost and turn it up a little at a time till the gauge reads 13psi consistently?

    Please and Thanks!

    i'm not to sure on the EZ models; mine i had to calibrate. I then enter the boost values i wanted for the low and high setting, also has a scrabble function. yours does not have the read out, so i highly suggest you get a boost gauge and wideband before installing controller. just play it safe and don't forfeit your engine.

    That sounds right just ease it up little by little desired boost has been reached.

    You will probably need a Factory fuel cut diffuser of some kind, not for sure on what max boost in factory trim is but probably right around 10-12 lbs.
