ME221 Standalone Fuel Injection ECU, Ford Zetec Plug and Play Pack

The ME221 Wire-In ECU is a feature rich and future proof four cylinder injection engine management system. Built from the ground up using the latest control strategies means a modern, powerful, VE based ECU, with enhanced feature set including closed loop boost, in-built Wideband Lambda Control, DSP Knock Control, on-board data Logging and VVT control – all in a compact form factor. Massive IO means the ME221 can handle anything thrown at it, and custom tables means any specific algorithms required can be easily derived.

The ECU comes complete with a fully terminated Ford Zetec 1.8/2.0 Blacktop loom to get you up and running in no time. It is suitable for either the stock inlet, or throttle bodies.

The connections provided in our FORD ZETEC loom are:

4x 2 PinMini-Timer for the Injectors

1x 2 Pin Mini-Timer for Cam Sensor

1x 2 Pin Mini-Timer VR Type Crank Sensor

1x 2 Pin Mini-Timer for Idle Control Valve ○ Depending on stock location as it can differ by year you may need to extend this.

1x 2 Pin Mini-Timer for IAT and Coolant sensor ○ Note may need extending/changing depending on the engine type. Use OEM connectors. ● 1x Ford Coil Pack Connector

1x 3 Pin Mini-Timer for throttle sensor ○ Typical if using throttle bodies - may need to change if keeping OEM throttle sensor though this is rare.

1x 3 Pin Mini-Timer MAP sensor (suits our 3 Bar Sensor)

Auxiliary flying wires for spare outputs, tachometer, knock and O2/Lambda.

Loom details can be found in this document.

What is in the box:

1 x Standalone ME221 Engine Control Unit (ECU)

1 x Zetec Loom (supplied as standard with 2 pin mini timer injector connectors to suit standard Zetec, please see our other listings for motorcycle injector connectors) 

Options

Coolant and air temperature sensors. The ME221 and MEITE software do offer the ability to calibrate the ECU to read any sensor, however by using the sensors on offer in this listing the standard calibration tables can be used - vastly simplifying the set-up process and saving considerable time. Both sensors are M12 x 1.5 thread. The additional coolant temperature sensor housing offers a quick and convenient method for installing directly into a radiator top hose and negates the need for tapping out existing holes in your cylinder head.

Crank Sensor. The ME221 ECU will work with the standard Zetec crank sensor. This sensor is therefore offered as a direct replacement and only required if you are unsure of your existing sensors condition or reliability. 

Data Cable (FTDI USB-Serial Adaptor). Whilst the ECU comes with an RS232 cable many modern Laptops do not have such a connection. Therefore this adaptor will allow a USB port to be used for connectivity. This genuine FTDI cable is guaranteed to work with this ECU, unlike many cheaper alternatives that often suffer connectivity issues.

Basemaps

ALL ME221 and ME442 ECU's are shipped with a test map only. This is highly unlikely to run your engine and if it does it will not run it very well! A library of basemaps can be found here on the Motorsport Electronics Support Pages as well as a full suite of installation manuals. danST Engineering can also provide basemaps for a variety of engines developed on our in-house rolling road.

Coil Pack Compatibility

This ECU is intended for use with wasted spark Ford coil packs. Other wasted spark coil packs may be compatible however please contact us before attempting to use alternatives to avoid potential damage to the ECU. The fitment of a Ford coil pack (available in our shop) will guarantee compatibility and reliability.

Note: As with all after-market engine management systems (ECU’s) a dyno tuning is recommended to avoid damaging your engine and to get the most out of your engine. A full range of basemaps are available online from danST engineering or Motorsport Electronics.
