Functions & Hardware
RPM
The unit can detect engine RPM using the tachometer signal. This could be available at the ECU or the ignition module of the car. Alternatively, a signal wire going to an ignition coil or injector could be used.
Temperature
LDperformance RACE DASH has 3 temperature inputs - Coolant, Air and Oil. They are identical. Suitable sensor is available from LDperformance.
Pressure
Three inputs are available – OIL and Fuel Pressure and Boost. These use 3 wire sensor available from LDperformance. The sensor measures up to 10 bar (150psi)
Serial Port
The wiring harness includes a serial port cable. It can be used to get data from the ECU or to configure the DASH from a laptop using USB to serial adapter. The GPS module also connects to the serial port so it is not possible to use GPS and connect to an ECU through the serial port at the same time!
CAN BUS
Used to connect to most ECUs.
GPS
Additional GPS module is available. The gps module is connected to the serial port cable. It's used to read vehicle speed in kph or mph. The old type gps module is connected like this:
EGT
Dash2 can also read EGT sensor directly. All that is required is to connect EGT probe according to the wiring diagram. Polarity is important – it will not work if the wires are reversed.
AFR
The input is 0-5V which corresponds to 7.4 – 22.5 AFR commonly used by wideband controllers as well as the LDperformance Wideband Controller.
