The ND Miata deserves a tune that matches how good the chassis already is.
The 2015 Mazda Miata 1.5L NA 1.5L naturally aspirated engine is a willing, high-revving unit in one of the best-balanced sports cars ever made, and the factory ECU doesn't leave room for proper calibration around 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 sharper and more linear through the rev range
- Fueling that's precise and stable, not chasing factory trims
- Power delivery that complements the balance the Miata chassis already has
- Consistent behavior at temperature, not drifting as the engine heats up
- A tune built specifically for your modifications and your driving
