ME221 Universal 4 Cylinder ECU + Ford Zetec PnP Loom

Motorsport Electronics now offer the ME221 Wire-In ECU with direct fit ‘Plug and Play’ looms for the Ford Zetec & ST170 engines. As the core of their PnP EMS range, the ME221 has taken the UK by storm, particularly in the MX5 market - and after 24 months of real world usage by real world customers, they offer the system in a new, universal form factor, suited for accurate, reliable, and fully-sequential control of four-cylinder petrol injection engines.

This version includes a professionally made ‘click and go’ loom for the Ford Zetec Silvertop/Blacktop and ST170 engines. They even supply with the ECU dyno developed maps for both the OEM inlet and also throttle bodies and turbo applications.If you want to get your Zetec up and running on fuel injection, be that using the OEM inlet, a set of AT Power throttle bodies, or even if you’re turbocharging it, the ME221 will deliver the precise fuel and ignition control you need, utilising all of the factory sensors and outputs. (Of course you can customise your injectors and sensors to suit, and just recalibrate the ECU!)

Indeed their base-maps don’t suit all setups - and in that case, get stuck in with the free MEITE tuning software and carry out tuning the fuel VE table & ignition advance, or setting up advanced features such as launch control, anti-lag, switchable maps, closed loop boost control, idle control or even full closed loop VVT control on engines such as the ST170 (this alone can add 40lb/ft as opposed to having to ‘lock’ the cam as you would with ECUs that don’t support VVT). 

They are so confident in the ME221, They even give you a LIFETIME WARRANTY...
