The Genesis Coupe 2.0T is a genuinely capable turbocharged platform, and standalone ECU support through the Haltech Nexus gives you direct access to what it can do.
The 2014 Hyundai Genesis 2.0T Theta II 2.0T is a capable platform with real tuning potential, but standalone ECU support for it is limited. The Tuned By Shawn Boomslang PNP Wiring Harness for the Haltech Nexus connects directly to your factory harness without any permanent modifications, giving the Haltech Nexus full standalone engine control. No cutting, no splicing, fully reversible.
