HKS EVC 5 Boost Controller
 

Condition is 100% on functionality and 85% on physical appearance. No real scratches or anything. Lights up proper and looks gorgeous.

I also happen to have the optional "scramble boost" button which is a momentary switch that activates a second stage of boost for your preset amount of time.

This boost controller has always been my favorite. It is rock solid consistent within .2 psi from pull to pull in the same conditions. Of course, like any boost controller, if the weather has changed drastically than you will need to turn it up or down a few percent to accommodate if you are trying to regulate boost within half psi tolerance.

The ONLY reason I am selling this is because I need to move to a setup that will allow me to program the boost to gradually increase as vehicle speed increases. I am getting ready to build the car for big power and I wont be able to run full boost at lower speeds. I have no complaints about this boost controller and have never had an issue with it. Trusty little guy it has been.

Installation is as simple as it gets with the only required wiring being a power and a ground, boom, done. The wiring between the controller, brain, and solenoid (stepper motor i believe which is actually much better), is plug and play with the included harness.

DOUBLES AS A BOOST GAUGE WITH PEAK-HOLD. I have never needed a boost gauge with this controller because it has a live boost readout, and right above that readout it tells you the highest boost you have hit since you last reset the peak-hold.

I am the original owner of this boost controller, so it hasnt been installed in a million cars, just my 350z and then my 370z.
