This product is a plug-in ECU designed specifically for the Nissan 200SX / Silvia SR20DET S14, and the S13 CA18DET. It’s a direct plug-in to the factory wiring and allows you to expand the system to use all the features of the 440 ECU.






Connectors 76-pin connector (same as factory ECU)
Mini USB port for connection to laptop
2x 2.5mm jacks for serial communications (one to connect to external loggers and dashes, the other to connector to slave devices such as wideband oxygen sensor controllers)
3.5mm headphone jack for listening to knock
Physical Dimensions (mm) 205 x 147 x 33 mm (including mounting tabs)
Mass 0.8 kg
Looms available None (use factory loom)

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
Vehicle speed inputs 4 inputs – digital or reluctor
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
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, 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).
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 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)
