E5A Euro 5 Generic Controller for 3 & 4-Cylinder DI + PFI Engines

Cost effective generic controller for engine development and durability tests.
E5A Euro-5 is an all-in-one module which can control 3 and 4-cylinder engines having both direct injection and port fuel injection.


E5A Euro-5 is a cost effective generic engine controller with a customer driven software development intended for use in development and durability tests.  The ECU can control engines having up to 4 direct injection and 4 port injection injectors.  It is designed for 3 and 4-cylinder engines with combined direct and port fuel injectors.
Software is specifically developed for engine development and testing.  It includes the ASAP3 communication protocol, used for data exchange with test cell computer systems for automated test and mapping features.


Euro-5 includes all the usual features found in a high end engine management system designed for engine development work of durability testing.
Among the special features are for example:

  • Automated test procedures using ASAP3 communication protocol
  • Easy test cell integration
  • Operator controlled override functions of most calibration parameters
  • Unique mapping procedure with closed loop automatic generation of calibration data
  • Programmable cylinder firing angles
  • Engine load as MAF, MAP or TPS; N/A, turbo charged or supercharged
  • Easy adaptation of crankshaft and camshaft trigger patterns
  • For use with engines having from 1 to 4 cylinders
  • Inputs for several sensors with SENT communication protocol

  • Ignition coil drivers for logic and power coils
  • Random spark sequence and offset generator

  • Controls up to 4 drivers for direct injection plus up to 4 drivers for port fuel injection
  • 0-100% blend between DI and PFI injections
  • Up to 4 DI injections each cycle
  • Injections measured as fuel mass flow

  • Cylinder de-activation strategy
  • Boost control for electronic waste gate
  • EGR valve control
  • Variable oil pressure control
  • Variable camshaft timing for up to 4 camshafts
  • Possible to connect up to 5 wide band lambda sensors
  • 2 selectable calibrations
