Sensor Interfaces |
|
| Crank angle sensor type | 3 programmable inputs, reluctor or hall-effect/optical, configurable as triggering ignition timing, injector drive, ignition timing during cranking, or cylinder 1 marker. Capable of triggering off rising and/or falling edge on the same trigger input pin, internal pull-ups for hall-effect/optical trigger inputs |
| Crank angle trigger waveforms | Sync / trigger / multitooth / missing tooth (versatile programmability) Nissan optical Mitsubishi style with 2 sync pulses Virtually all factory triggering systems |
| External Manifold Absolute Pressure (MAP) input | 0 – 5V, 2-point linear calibration, range 0 to 400 kPa (5V supplied by ECU) There is also an internal 4 bar MAP sensor inside the ECU |
| Air, water and aux temp inputs | 4k7 pull-up (requires separate thermistor connected to ground), 32-point linearly interpolated calibration, range -30 to 125°C |
| EGO input | 0 – 1V factory narrowband, or Bosch “wideband” – input impedance 10 MOhm. Can connect 0-5V linearised sensor (eg PLX, M&W UEGO) to aux input Can connect 0-3V Zietronix sensor to analogue input Can connect M&W UEGO, TechEdge, Innovate LC-1 and TC-4 on secondary serial port |
| Knock input | High impedance input, filtered |
| Throttle position (TPS) input | 0-5V (5V supplied by ECU), 2-point calibration |
| Auxiliary digital inputs | 8 inputs, each configurable as active-high or active-low, 12V tolerant inputs |
Actuator Interfaces |
|
| Number of injector drivers | 4 |
| Injector driver waveforms | Full sequential Batch Semi-sequential every period or semi-sequential every second period Half/third/quarter speed full sequential Fire all at once every cylinder 1 (as on Swift GTi, Alpine Renault) Optional batch fire during cranking |
| Injector driver current | Optional constant current or peak-hold drive, selectable steady-state current of 0.5A, 0.9A, 1.5A or 1.9A |
| Number ignition outputs | 4 (using 4th channel disables aux output 1) |
| Ignition output waveforms | Selectable as firing on rising edge or falling edge |
| Ignition output type | Open-collector with 560Ohm pull-up (allows direct connection to OEM transistor or separate igniter box) |
| Number of auxiliary outputs | 8 (or 7 if using 4 ignition channels) |
| High current outputs | Max current 7A (or 3A inductive), 3 of these PWM capable, PWM frequency selectable (23Hz – 2kHz) |
| Low current outputs | Max current 200mA – suitable to drive relay coils |
Control Characteristics |
|
| Map points | 512 cells per fuel/ignition map, dual maps which can be toggled with digital input. |
| Load determination and Tuning Modes |
Optional Volumetric Efficiency Tuning TPS or MAP based |
| Injector pulse width resolution | 0.7µs (0 – 44ms) |
| Ignition resolution | 0.2° (0 – 51°) |
| Dwell time resolution | 0.1ms (0.1ms – 5ms) Dwell time reduction for high RPM with high dwell time |
| Accelerator pump | TPS and/or MAP based (configurable proportionality) as well as asynchronous accelerator pump. Works with TPS pot or switch – pot gives better performance |
| Fuel control strategies | Open loop, closed loop, and two adaptive modes (requires EGO sensor) – can run open loop above a specific MAP if required, target AFR can be set across rev and load ranges. Flex Fuel capability (requires fuel composition sensor to be fitted). |

| Ignition control strategies | Trim tables based on Coolant Temperature and Air Temperature |
| Idle control strategies | Open loop values with a 32-entry temperature table Target idle speeds with 32-entry temperature table Idle effort correction for air temperature Idle-up functionality based on A/C request, electrical loads, power steering Can adjust ignition timing for closed loop idle control, as well as various types of idle control valves (2 wire, 3 wire, 6 wire stepper, and 4 wire stepper using an external driver available separately) |
| Main loop speed | 400 Hz (approx) |
