Suits: Plug n Play replacement of the factory ECU for Mazda Miata (MX-5) NA 1.6L and 1.8L with 2-plug, 2-row factory ECU. Manual transmission only.
Includes: Nexus S2 ECU, Injection molded plastic plug n play adaptor harness, M14 x 1.5 air temp sensor with matching plug and pins, auxiliary I/O 16 Pin Tyco plug and pins.

All manual transmission 1.6L variants will require the factory throttle position sensor to be unplugged and removed. A full-range throttle position sensor alternative must be installed for correct functionality. Failure to do so will result in erratic behavior of the ECU at wide-open throttle along with damage to the ECU. Using a Nexus S2 instead of a Nexus S3 will reduce some of the cars factory functionality. Refer to the quick start guide for details.
