The Adaptronic 420. The current version is the e420c, which replaces the original e420b model.

New versions will be brought out as new technologies become available and new needs become apparent.

Standard ECU Features

"3D" Fuel and Ignition maps (as on any sophisticated aftermarket ECU).
Configurable ignition and injection outputs to suit different applications.
Inputs for water temperature, air temperature, auxiliary temperature (eg turbo),
manifold air pressure, throttle position, knock sensor, EGO (exhaust gas oxygen).
Outputs for four injector groups - allows full sequential injection up to 4-cylinders,
or semi-sequential injection up to 8- cylinders.
Outputs for three igniter groups (four optional) - allows full sequential spark up to
four cylinders and wasted spark systems up to 8-cylinders, or any
conventional distributor systems.
Eight configurable auxiliary outputs - four of which are configurable as
high current outputs, three of which are PWM capable.
PC interface.
Field upgradeable firmware.
Eight configurable auxiliary digital inputs.
Datalogging via PC software.

Special Features

Adaptive fuel control - with configurable tolerances and loop gains,
and conditions under which adaptive behaviour takes place.
Narrow-band (factory EGO sensor) closed loop fuel control.
High current programmable outputs - allows direct drive of solenoid valves
for boost control, air bypass etc.
Special function programmable outputs - allows control of anti-pollution
purge valves, air conditioners etc.
Open-loop and closed loop idle bypass control - allows configuration of
increased idle bypass amount based on low battery, electrical load,
air conditioner, as well as correction based on RPM.
Programmable for different crank angle sensor waveforms.
Many other features.
