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: 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.

Notes: Does not support USDM OBDII 96-97, Special Edition SE and Anniversary models. 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.
