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.”

Please note that if you are using a switched type TPS sensor as fitted to the 1.6 model, we suggest installing a variable TPS to give better throttle response – the 1.8 model already has the variable TPS as standard. Also, if you wish to run without a MAF sensor, then you will need to install an Intake Air Temperature Sensor – available in the options list.
