Hi,
I have a HKS EVC6 boost controller for sale. Come with the harnesses, but I don't have the stepper motor/solenoid. You can try to find one online somewhere. I have tried directly with HKS with no luck. This has been perfectly tested with a buddies solenoid. Powers up and connects to a solenoid with ZERO issues.
Normally they go for $650.00. Asking for $250.00 shipped. Priced because of the missing solenoid.
