Other sensors - seems very smooth

The Throttle Position Sensor (TPS)

This unit is fitted to the throttle shaft and senses the throttle position. at idle speed voltage is 5.0-4.5 volts and at full throttle the voltage drops to 0.5 volt.

The Manifold Absolute Pressure (MAP) Sensor

Depending on the manifold pressure, the sensor regulates between 0.25 to 4.75 volts.

The Air Charge Temperature (ACT, MAT) Sensor

This sensor is of the NTC resistor type, its resistance decreases as temperatures increase.

Engine Coolant Temperature (ECT, CLT) Sensor

The ECT is also of NTC resistor type and its operating range is identical to that of the ACT.


Actuators:

Ignition module

The ECU sends a Spark-out signal to the ignition module

Coil - would you really want to use the unknown ignition module when this coil could be driven directly ?

The Fuel Injectors

The ECU provides accurate control of the solenoid operated fuel injectors to discharge fuel.

The Idle Speed Control (ISC) Valve

This unit is regulates the engine demand for air depending on the engine temperature, engine load, or swithed on accessories.

The valve, whichis controlled by a variable current from the ECU, adjust the air flow into the engine.

The valve is pwm modulated.

The Boost Pressure Control Valve

This solenoid valve is directly connected to the high pressure side of the turbocharger by a hose. Depending upon whether the valve is open or closed it will either "vent-off" a portion of the boost to the inlet side of the compressor (valve open) or direct it to the wastegate actuator (valve closed)

I need some advice about the hw configuration of vems.

Thx any help!
