Very specific device for fitting particular Toyota engines with stock ECU to old chassis types

Features:

1) Controls ECU modes: ECT Power/Snow, A/C idle-up, ELS (raise idle RPM for high electric load condition)

2) Converts RPM signal for analogue instrument panel per pre-defined settings: 6 to 4, 8 to 6, etc

3) Controls cooling fan in several ways: either with simple on/off relay, or with external or built-in PWM module. Supported are Toyota and Hyundai power modules, and integrated fans like BMW E46 or range of Mercedes fans. PWM mode allows for stepless fan speed control. Input signal: either MPX (for Toyota ECUs equipped with that option) , or separate analogue temp sensor.
