The ME442 MX-5 Plug-In is our latest Engine Management System for the Mk1 (3 Plug NA) MX-5 / Miata, years 1996-1997. This package includes the LSU4.9 Sensor and Direct Connect Cable.
You may have a later 1996-1998 Mk1 (with pop up headlights) but if your car has TWO plugs that connect to the ECU then you need the 1989-1995 version here. This is the 3 plug ECU version.
Every major and respected MX-5 Tuner in the UK, as well as the biggest, Flyin’ Miata in the US, recommends the ME Engine Management System over other systems – see our forum post here for more details and feedback on the system
Nick, Skuzzle Motorsport – review from MX5Nutz
“I have just spent the last few weeks playing with the fairly recently released Motorsport Electronics ME221 PNP ecu and finally after years of supplying, fitting, mapping MegaSquirt of all shapes and sizes, I am proud to announce that from this day on, my ECU of choice for most MX5 applications is now the ME221.”
