- The MF2 is based on an open-architecture design, which means that the unit is freely re-programmable at any time, open to any one who possesses a small screwdriver: no computer interface is necessary! If this interests you, read on ... working alongside the original ECU, the MF2 controls its own set of injectors, four high-impedance injectors and two low-impedance injectors (not supplied). It is able to use the signal from the existing sensors, or it can operate independently. 3D-mapping is simple if a load- or pressure- signal is fed into the unit.
- for applications where load signal (throttle angle sensor) or manifold absolute pressure sensor (MAP sensor) is available, the pressure can be used in conjuction and enhance the 3-D mapping.
- An additional pair of wires supplies a stablised output voltage of 5 volts for driving a MAP (manifold absolute pressure) sensor.
Voltage converter IC
This little integrated circuit converts the incoming +12 volts DC supply to +5 volts for powering optional Manifold absolute pressure(MAP) or optional Throttle angle sensor
- The injector plug comes complete with mating pins and splash proof seal, which enables direct conection to a BOSCH type fuel injector.
- Eight half-turn potentiometers (clockwise for more fuel) provides enrichment curve at 1000 rpm intervals and are electronically interpolated to give smooth change-over points. Factory preset at 1/4 turn
- input gain potentiometer
25 turns gives full pressure input gain (factory preset at 12T) when used with manifold absolute pressure (MAP)sensor or throttle angle sensor within the 0-5V input range.
- Pressure threshold potentiomater
25 turns sets the full pressure input signal cut-in point (factory preset at 12T).

thats all info i could find

its not so hard to set it up when u have a wideband lambda installed on yr car(with logging capabilities), that way you can set it up nicely, i would call it an investment, and gives YOU the control
or go to a good tuner to have it set up for you.
the kit (excluding map sensor and injector(s)) costs about 200 pounds.
edit : the TechEdge wideband costs about 320,
