The xB 2ZR-FE is a practical, reliable engine that benefits from proper calibration more than most people give it credit for.
The 2015 Scion xB 2ZR-FE is a well-sorted platform with a loyal following, but the factory ECU limits what's accessible for serious modifications. 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
- Throttle response that's crisp and direct, not filtered through conservative factory logic
- Fuel and ignition timing calibrated precisely to your actual setup
- Idle stability that's consistent regardless of temperature
- Engine behavior that reflects your modifications accurately
- A foundation your tuner can properly build from

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