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

4 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
TPS using 2nd map as MAP backup
MAP using 2nd map as TPS backup
Both maps MAP or TPS, digital input to select
MAP and TPS map, digital input to select
MAP and TPS map, use MAP on closed throttle, otherwise TPS
Use max/min/average/sum (MAP, TPS)
Read TPS from map and multiply by value in MAP table

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 (requires EGO sensor) - can run open loop above a specific MAP if required, target AFR can be set across rev and load ranges.

Fuel correction

Trim tables based on Coolant Temperature and Air Temperature, Dead-Time correction

Ignition control strategies

Trim tables based on Coolant Temperature and Air Temperature

Idle control strategies
