    Description

    This Adaptronic 420 ECU is a wire in solution for those looking for an entry level premium engine management system with many extra features that make it stand out from the rest.

    Standard Features

    • Compatible with most engine types (use our selection guide)

    • 4 ignition and 4 injector outputs, fully sequential operation

    • 7 or 8 auxiliary outputs with more control functions than you can point a stick at (eg 2 x closed loop VVT, boost control, idle control)

    • Launch control, antilag, flat shift and boost by gear all standard

    • Serial input for wideband O2 sensors (we recommend the MTXL)

    • Serial output for communication with dashes and dataloggers (we recommend the Race Technology units)

    • Inbuilt 4-bar MAP sensor

    • Headphone port for listening to the knock sensor while tuning

    • Basic closed loop ignition control

    • Closed loop fuel, idle, boost, 2 x variable valve timing control

    • Easy to use software

    • 4 programmable digital inputs

    • Dual maps

    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)

    142 x 142 x 33 mm (including mounting tabs)

    Mass

    0.4 kg

    Looms available

    0.5m long (for connection to existing loom)

    2.0m long (for wiring directly to engine)

    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

    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

    Main loop speed

    400Hz approx
