ME221 Standalone Fuel Injection ECU, Ford ST170 Plug and Play Pack
The ME221 is the latest engine management system from Motorsport Electronics and available from us here at danST Engineering.
We are pleased to now to be offering the ME221 Wire-In ECU with direct fit ‘Plug and Play’ looms for the Ford Zetec & ST170 engines. As the core of our 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, we can now 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 ST170 engines. We even supply with the ECU dyno developed maps for both the OEM inlet and also throttle bodies and turbo applications.
This ECU is ideal for use with our popular bike throttle body kits.
Designed for fully sequential control of four cylinder engines, as well as forming an integral core to the range of ME221 based PnP ECUs, it is a feature packed ECU, in a compact, reliable and affordable form factor.
The ME221 uses the same high accuracy Position Timing Module Core and the powerful proprietary tuning software (Motorsport Electronics Integrated Tuning Environment, or MEITE) as developed for control of a unique Le Mans engine.
With support for a range of OEM sensors and trigger patterns, as well as being versatile enough to offer flexibility where it’s needed - including often ‘expensive’ features such as Fully Sequential fuel control, Flex-Fuel, Closed Loop Boost & VVT as well as Windowed DSP Knock Control through to core features such as programmable inputs, custom tuneable sensor tables and full 3D mapping, the ME221 really blurs the line between lower priced and higher featured engine management systems.
Current ‘out of the box’ supported engines include :
Mazda Miata 89-05
Ford Zetec/Zetec SE/Duratec/ST170 (inc VVT)
Vauxhall XE ‘Redtop’ or LET Turbo
VW 4 Cylinder Engines (using 60-2 Trigger)
Peugeot/Citroen TU5 Engines
Renault Clio Sport 172/182 F4R Engines (& Megane)
Essentially any port injection, four Cylinder engine, either turbocharged or normally aspirated can be ran semi or fully sequential with an array of motorsport features to boot, all powered by the ME221 ECU.
This system includes the ME221 ECU, Zetec Wiring Loom, RS232 Tuning Cable & Quick Start Sheet.
2x IGBT Coil Drivers for Direct Coil Drive
4x High Impedance Injector Drivers (Can be used to drive two injectors each, or as spare Low Side Drivers)
3x Spare 10A Low Side Drivers (User Assignable features, ie Fuel Pump, VVT, Boost Solenoid etc)
1x 12V Tachometer Output
2x VR/OPTO/HALL Crank and Cam Signal Inputs
1x Knock Sensor Input
7x Analogue Sensor Inputs (Can be used as digital inputs)
What is in the box:
1 x Standalone ME221 Engine Control Unit (ECU)
1 x ST170 Loom (supplied as standard with 2 pin mini timer injector connectors to suit standard Zetec, please see our other listings for motorcycle injector connectors)
1 x RS232 Communications Cable
1 x Quick Start Guide
What else will i need?
The ECU requires inputs from a crank sensor (36-1 or 60-2 pattern) Therefore if your engine is not equipped with a sensor you will need to mount a suitable sensor and trigger wheel on your front pulley. The ECU also requires inputs from air and water temperature sensors. If your laptop is not equipped with an old style RS232 port you will need a genuine FTDI serial adapter cable if you wish to connect to the ECU.
All of the above can be purchased online from danST engineering-please see our other shop items.
Further information, installation manuals and a library of basemaps can be found here on the Motorsport Electronics Support Pages
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
