The 2003-2013 MZR generations and their market-specific ECUs require direct verification. The 1.3L Skyactiv-G arrived during the final MZR generation and can overlap by market and model year. The 1.5L Skyactiv-G and Skyactiv-D belong to the 2014 and newer generation. The 2.0L Skyactiv-G is restricted to selected markets and model years.

Priorities for the Mazda2, Demio and Toyota iA
Protect daily manners
Build the calibration around clean response, predictable part-throttle behavior and the fuel actually used.
