The ME221 MX-5 PnP is the latest plug-n-play Engine Management System from Motorsport Electronics for the 1999-2000 Mk2 (NB) MX-5 / Miata.

This ECU’s is ideal for use with one of our popular bike throttle body kits.

It supports the  1.6/1.8 model, and also fits the OEM case, which means the conversion installs tidily into the OEM position. It also supports the stock 'smart; alternator' control.

The only extra thing you need to do besides plugging it in is run a MAP vacuum hose (supplied) from the ECU to the intake manifold.
