2.4 Analog/Temperature Inputs
G4 ECU's have plentiful analogue voltage and analogue temperature channels. The
difference between volt and temperature channels is temperature channels have an internal
pull-up resister.
All analogue volt channels are created equal and can be wired to any type of analogue input
(there is no restrictions as to what must be wired to each channel).
Analogue Volt Inputs may be configured to accept an analogue signal between 0-5V.
Applications include:
· Narrow-band O2 (0-1V output)
· Wide-band O2 (via external wide-band controller)
· 0-5V Voltage (e.g. Boost Adjust)
· Pressure (from 0-5V transducer)
Temperature channels are designed to be used only with PTC or NTC thermistor sensors.
Almost all factory temperature sensors fit this category. Do not wire the output of a 0-5V
temperature sensor (e.g. a pyro. module) to these channels, instead use an Analogue
Voltage Input.
Analogue Channel Specifications:
· Measurable Input Range 0-5V DC
· Input impedance 2.2M Ohm DC (4.7k Ohm AC).
· Maximum Input Voltage +/- 50 V
· Temperature Channel Pull-up Resister 1k Ohm to 5V
2.5 Digital Inputs
Digital Inputs are inputs that recognise either a high (+V) or low (GND) signal. Digital inputs
are typically set-up to monitor the position of manual switches or connected to sensors that
output a signal of variable frequency.
The following Digital Input Limitations Apply:
· Only Digital Inputs 1 to 6 can be used for frequency input (e.g. speed).
· Only Digital Inputs 1 to 4 can be used for Variable Valve Timing (VVT) cam position
input.
G4 ECU's have up to 10 Digital Inputs that can be configured for sensors/ switches such as:
· Vehicle Speed Sensor
· Antilag Switch
· Clutch Switch (for launch control and flat shifting)
· High / Low Boost Switch
· Water Spray Switch
· Dual Fuel / Ignition Map Switch
