IMF - Model ECU MASTER LITE -Control Ignition and Injection Unit

MASTER LITE - HALL or INDUCTIVE ?

1. What type of engine pick up sensor is used
1. Inductive - passive inductive sensor eg S01, S04, S05 (two wires)
2. Hall - integrated sensor Hall, Optical, Namur eg H01, H02, H03, F03, N08
2. What type of ignition coils is used
1. Two-wire - common
2. Three-wire - common or digital (digital requires inversion of production outputs)

ECU MASTER LITE unit compared with MASTER standard (in aluminum case) is reduced by these signals AI2,AI3,AI4,DI2,DI3, DI4, PB,1OC,1OD,DO1,DO2. All software functions including injection support are preserved. In MASTER Control application is only necessary to choose  HARDWARE VERSION → V7.X. Documentation at the bottom is however uniform for all versions of ECU MASTER units!

The unit ECU MASTER ignition has been functionally designed in order to control advance or injection of combustion engines ranging from one to four cylinders, with whatever configuration of scanned teeth, types of sensors and features like 5D maps of advance and injection control, temperature, tachometer output, strobe lamp, charging control, engine speed and turbo preassure PID regulation, control switching on of fuel pump. Unit LITE contains only 2 TCI outputs.

The list of features mentioned above determines ECU MASTER ignition to be used either for a service or tunning replacement of conventional motorcycle or automobile ECU units, usable for ignition or injection coil control. The integrated redundancy of sensing, together with other key features makes ECU Master ignition very suitable for marine and aviation applications, moreover, thanks to the wide range of operating revolutions can be also used for turbines.

The function of ECU MASTER ignition relies on FPGA technology, which provides digital-analog conversion of sensor signal, as well as its evaluation and calculation of the mathematical model of the real rotation. Simultaneously, it deals with other operations i.e. redundancy sensing, total control of CDI converter, advanced features and signal records. FPGA technology is interesting not only for its high operating performance but particularly for its accuracy, which in principle microprocessor-based systems cannot achieve.
