CMP sensor is used to determine in which of the two crank revolutions
the engine is. This is used during cranking.) Inductive or Hall
 ECT (Engine Coolant Temp)
 Fuel Temperature (for display purpose)
 Fuel Pressure
 Oil Pressure
 Lambda sensor (NIRA i7x Street controls Bosch LSU 4.9 lambda
sensor without external electronics)
 EGTC (Exhaust Gas Temperature. Measures the exhaust gas
temperature in the exhaust manifold where the headers collect. NIRA
i7x handles either digital egtc reading, resistive reading or 0-5V analog
input)
 Flat Shift Switch
 11 Aux inputs ( 3 Analog inputs, 6 Resistive temp sensors, 2 Digital
inputs)
1.3.2 Input Controls (driver controlled)
 Switch for Anti Lag System (ALS, response system)
 Button for Launch Control
1.3.3 Output Functions
NIRA i7x processes the input signals and controls the output signals in order
to manage the following actuators.
 8 Fuel injectors (amount and sequence)
 8 Ignition coils (timing and dwell time). NIRA i7x controls active coils
(with integrated drivers) or passive coils that are connected to NIRA
i7x via an external ignition driver
 Boost pressure control valve (controls boost pressure H bridge or
PWM output)
 IAC (Idle Air Control; controls engine idle speed via ignition
compensation and an IAC valve or motor)
 Fuel pump relay
 Main relay (for actuator power supply)
 Fan relay (for controlling radiator fan)
 Tachometer output (engine speed)
