Linear Sensors
Wiring
Temperature Sensor
Temperature sensors are passive devices that measure temperature through the use of a thermistor, a resistor that varies resistance with temperature.
We recommend using a dedicated, two wire ECU-style sensor for best results.
Pullup resistor
A pullup resistor is needed to create the necessary voltage divider circuit so RaceCapture/Pro's analog input can sense temperature as a varying voltage. This pullup resistor is connected to the 5v reference on the RaceCapture/Pro terminal block.
Use a 2.2K ohm pull-up resistor for high resistance ECU style sensors such as:
- GM-style TX3 / SU109 Coolant
- GM-style AX1 / SU107 Air Inlet Temp
- AEM 30-2012 1/8" NPT fluid temperature sensor
Use a 220 ohm pull-up resistor for low resistance gauge type sensors such as:
- VDO 323-095, 325-002
Sensor Ground
Two wire temperature sensors have one sense lead and one ground lead. for best accuracy, connect the ground lead to the same ground point as RaceCapture/Pro.
One wire sensors have the ground as the body of the sensor. Ensure the engine is properly grounded to the chassis via multiple ground straps.
Pressure Sensors
3 Wire Active Sensors
Active pressure sensors are typically powered with 5V and provide a voltage output that varies with the pressure measured. Typically they have a linear response and are very easy to calibrate.

Sensor Breakout Board
We've created an optional sensor breakout / distribution board that will make it easier to use sensors that require pullup resistors as well as making available multiple ground and 5V Vref connections. The built-in pullup resistors are easily disabled by breaking a designated trace on the board. This board is compact; enough to be bundled inline with your wiring harness.
Hardware Expansion board <coming soon> look for it to fit into the RJ-45 jack in the back of the RaceCapture Pro. It can be used to develop your own sensors, or hook in some of the cleverer concepts we've come up with!
Adapter Board <coming soon> look for it to fit into the GPIO pins on the green removable bus in the back of the RaceCapture Pro.
