Inputs:
- Throttle position.
- Barometric (Atmospheric)/Boost pressure.
- Water (Coolant) temperature.
- Air temperature.
- Lambda sensor (narrow band).
- Battery supply voltage.
- Mapping adjustment for fuel and ignition.
- Crank sensor input (magnetic or digital type set in hardware by RTD depending on required application).
- Cam sensor input (magnetic or digital type set in hardware by RTD depending on required application).
- 3 x spare switch inputs (require ground/0V to activate).
Outputs:
- 16 x injector outputs capable of driving two sets of 8x2.5ohm injectors directly.
- 4 x ignition trigger signals for driving two dual channel ignition amplifiers for wasted spark.
- 6 x spare valve outputs which can be PWM switching or static and capable of driving up to 4A.
- 1 x tacho output.
Other details:
- ECU program stored in removable permanent EPROM memory. ECU map data stored in permanent EEPROM memory but changes can be made to maps via PC.
- Internal diagnostic data logging RAM for recording last half hour of engine data (at 5Hz). Data logging is automatically activated when engine revs exceed 2000rpm. Logging is paused when revs fall below 2000rpm. Data can be downloaded for storage on hard disk and viewed on a third party data analysis package such as Microsoft Excel or equivalent. Channels recorded are Engine speed, Throttle, Pressure, Water, Air, Lambda, Supply volts, Fuel injected value, Ignition advance, logging start/stop marker and error flags for Cam sensor, Throttle, Pressure, Water, Air, Lambda and Supply voltage.
- At least one RS-232 compatible serial port & one parallel port are required for PC-ECU communications.
- User can alter fuelling amounts, ignition advance, fuel & ignition compensations based on air & water temp and pressure input, individual cylinder fuel trims, injection delivery point, acceleration and deceleration supplements, ignition coil charge duration, injector phasing (double injector set-up only), soft cut and hard cut rev-limit, shift-light speed, launch control stutter, gear change cut and input sensor default levels.
- EMSPC V9.x ECU mapping software will operate under MS-DOS, Win3x, Win9x or ME operating systems. A third party driver (DIRECTIO) is required to enable use with Windows NT, 2000 or XP. New windows based mapping software is currently under development.
