Temperature Sensors

Engine Temperature

Mfg	Pic	Pigtail	Part Numbers	Mechanical	Analog Configuration	Notes
GM			Wells SU109 : Standard Motors Products (SMP) TX3 Pigtail Pico 5615pt	3/8" NPT threaded brass body and a 2 pin terminal.	<link to Race Capture analog channel configuration>	Can be used for air inlet temperature for normally aspirated engines
GM			Wells SU107 : Standard Motors Products (SMP) AX1 Pigtail Pico 5616pt	3/8" NPT threaded brass body and a 2 pin terminal.	<link to Race Capture analog channel configuration>	Use for measuring air inlet temperature. Exposed sensing element, necessary for boosted engines where fast response times are necessary. Due to the fragility of the sensing bulb, it is necessary to pot the base of the sensor leads with sensor-safe silicone when used in high vibration environments.

Oil Temperature

Ambient Air Temperature

Infrared Tire Temperature

Mfg	Description	Pic	Pigtail	Part Numbers	Mechanical	Analog Configuration	Notes
TI	Infrared Temperature Sensor samples 3 positions on tire carcass		Needs dev board to connect to inputs.	Mouser Part #: 595-TMP006AIYZFT Manufacturer Part #: TMP006AIYZFT	*Texas Instruments : Board Mount Temperature Sensors Infrared Thermopile Sensor	<link to Race Capture digital channel configuration>	Can be used for 3 position tire temperature, when mounted within 3" of tire link

Pulse Sensors

RPM

Wheel Speed

Pressure Sensors

Fluid Pressure

Brake pressure sensors will be used to capture inline brake fluid pressure. Combining this input with brake pedal travel can provide a way to show brake fade in real time.

Boost / Vacuum

Mfg	Description	Pic	Pigtail	Part Numbers	Mechanical	Analog Configuration	Notes
GM	3.3 bar MAP sensor			Sensor: 9373269 Pigtail: 88987997	fastens with clips	<link to Race Capture analog channel configuration>	3.3 bar map sensor found on turbo GM products
DIY	Freescale MPX4250AP 2.5 bar MAP sensor		N/A	custom	custom	<link>	An extremely popular MAP sensor used in the Megajolt ignition and Megasquirt fuel injection systems. Can build up a simple circuit on perfboard and be powered by 5V v-ref from Race Capture

Distance Sensors

Suspension Travel

Mfg	Description	Pic	Pigtail	Part Numbers	Mechanical	Analog Configuration	Notes
DIY	Sharp GP2D12 optical distance sensor		3-pin connector	GP2D12	custom	<link>	Optical distance sensor measures from 10 to 80 cm and outputs a voltage corresponding to that distance. 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

Angle Sensors

Steering Angle

Mfg	Description	Pic	Pigtail	Part Numbers	Mechanical	Analog Configuration	Notes
DIY	Sharp GP2D12 optical distance sensor		3-pin connector	GP2D12	custom	<link>	Optical distance sensor measures from 10 to 80 cm and outputs a voltage corresponding to that distance. 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.

Throttle Position

Mfg	Description	Pic	Pigtail	Part Numbers	Mechanical	Analog Configuration	Notes
ASL	Ford type throttle position sensor		see pigtail below	Standard Motors SMP TH45 equivalent	custom		Existing style Throttle position sensor available from AutoSport Labs link

Brake Position/Pressure

Mfg	Description	Pic	Pigtail	Part Numbers	Mechanical	Analog Configuration	Notes
ATE	Brake Fluid Pressure sensor		solder on tabs (2 wire)	If your SKU number is 34331150922 than you'll want to reference OE Number 34331150922, 34-33-1-150-922, 80506001237.	<link to Race Capture analog channel configuration>		threads into T fitting on brake line.

DIY	Freescale MPX4250AP 2.5 bar MAP sensor		on part	ATV type sensor	threads into T fitting on brake line. Use professional brake fitting tools!		avail at 150psi, or 2000psi, needs 12v supply link

Linear Sensors

Wiring

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

Hardware Expansion board <coming soon> look for it to fit into the RJ-45 jack in the back of the RaceCapture Pro.

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.
