Haltech Nexus R5 VCU & Hyundai Tiburon 2.7L 2003-2008 Plug 'n' Play Adapter Harness Kit (HT-651415)

The Tiburon 2.7L V6 is a sporting platform that rarely gets the standalone ECU treatment, and this harness changes that.

The Hyundai Tiburon Lambda 2.7L is a capable platform with real tuning potential, but standalone ECU support for it is limited. The Tuned By Shawn PNP Wiring Harness Kit 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

• Throttle response that's direct and proportional instead of over-managed by the factory ECU
• 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
• A proper standalone foundation for a platform that rarely gets one

The Details

Built specifically for this vehicle's connector layout with OEM-spec connectors and correct wire gauge throughout.
