The Genesis Coupe 2.0T IMMO variant needs Haltech coil drivers, and this harness is built with that requirement in mind.
The 2014 Hyundai Genesis 2.0T IMMO 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.
Advantages
- Turbo response that's tighter and more predictable with a tune built for your actual boost targets
- Fuel and ignition timing calibrated precisely to your modifications
- Consistent power delivery that doesn't change with heat
- Idle stability that stays locked in regardless of temperature
