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."
It supports the 1.6 and 1.8 model from the same hardware, and also fits the OEM case, which means the conversion installs tidily into the OEM position. 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.
