Pressure Sensors

Oil, fuel Pressure

These sensors are appropriate for measuring fluid pressures in an engine. Not appropriate for measuring manifold boost or vacuum as these are relative pressure sensors. Use an absolute pressure sensor instead.

  • Linear response with an output between 0.5v and 4.5v
  • Technical Information
  • Default kit from AEM includes pigtail
  • Since these type of sensors have a linear output, replace the 4.5v value with the max pressure of the device in the units you prefer. e.g. 10 bar, 150 psi, etc.
  • Repeat the value through the rest of the calibration table.

To measure suspension travel, install a unit at each corner of car, targeting the road surface. May also be used for pedal travel as well, providing there is a target to sense. Create a target latched to the steering rod and use the travel out and back of the steering rack rod to denote the travel left and right for steering. This measures true steering(and ignores the speed sensitivity of steering systems, showing actual tire angle result, not steering wheel rotation). It also provides a quick way to verify alignment issues as location vs. gps/accelerometer travel in the "Straight ahead" direction will be at varying angles when alignment issues are present.

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.

Temp sensor connection.png

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.

((picture of active sensor))


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. SensorX board.png

SensorX

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.
