Adaptronic e440d Universal Select ECU

e440d

New product

This product is the template from which all the Select ECUs are derived. It can be used on most engines with 3 – 8 cylinders, naturally aspirated, turbocharged and supercharged applications, and has been specifically designed after years of market research with our previous generation ECU which this replaces, to cover the needs of 95% of applications.

This product is the template from which all the Select ECUs are derived. It can be used on most engines with 3 – 8 cylinders, naturally aspirated, turbocharged and supercharged applications, and has been specifically designed after years of market research with our previous generation ECU which this replaces, to cover the needs of 95% of applications.

It is a more feature packed version of the e420d. This ECU will also operate as a plug-in ECU for the NA6 and NA8 model MX5s / Miatas.

Specifications of the Adaptronic 420 ECU

Physical

Connectors2-plug connector (same as Mazda NA6 and NA8 MX5/Miata)
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)
Mass0.4 kg
Looms available0.5m long (for connection to existing loom)
2.0m long (for wiring directly to engine)

Sensor Interfaces

Crank angle sensor type3 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 waveformsSync / trigger / multitooth / missing tooth (versatile programmability)
Nissan optical
Mitsubishi style with 2 sync pulses
Virtually all factory triggering systems
External Manifold Absolute Pressure (MAP) input0 – 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 inputs4k7 pull-up (requires separate thermistor connected to ground), 32-point linearly interpolated calibration, range -30 to 125°C
EGO input0 – 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 inputHigh impedance input, filtered
Throttle position (TPS) input0-5V (5V supplied by ECU), 2-point calibration
Auxiliary digital inputs8 inputs, each configurable as active-high or active-low, 12V tolerant inputs

Actuator Interfaces

Number of injector drivers4
Injector driver waveformsFull 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 currentOptional constant current or peak-hold drive, selectable steady-state current of 0.5A, 0.9A, 1.5A or 1.9A
Number ignition outputs4 (using 4th channel disables aux output 1)
Ignition output waveformsSelectable as firing on rising edge or falling edge
Ignition output typeOpen-collector with 560Ohm pull-up (allows direct connection to OEM transistor or separate igniter box)
Number of auxiliary outputs8 (or 7 if using 4 ignition channels)
High current outputsMax current 7A (or 3A inductive), 3 of these PWM capable, PWM frequency selectable (23Hz – 2kHz)
Low current outputsMax current 200mA – suitable to drive relay coils

Control Characteristics

Map points512 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 resolution0.7µs (0 – 44ms)
Ignition resolution0.2° (0 – 51°)
Dwell time resolution0.1ms (0.1ms – 5ms)
Dwell time reduction for high RPM with high dwell time
Accelerator pumpTPS and/or MAP based (configurable proportionality) as well as asynchronous accelerator pump.
Works with TPS pot or switch – pot gives better performance
Fuel control strategiesOpen 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 correctionTrim tables based on Coolant Temperature and Air Temperature, Dead-Time correction
Ignition control strategiesTrim tables based on Coolant Temperature and Air Temperature
Idle control strategiesOpen 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 speed400 Hz (approx)
