FD EVO Digital Racing Gauge Display

FD EVO digital racing gauge display with the S-EXPAND expansion box, combining water temperature, oil temperature, oil pressure, boost, exhaust temperature, fuel pressure and voltage

The FD EVO works with both OBDII and the S-EXPAND sensor expansion box, so it can combine data from the factory ECU with readings from add-on sensors. It can also run on its own as a digital racing gauge, with no OBDII connection at all.

On an older or modified car, or for readings the factory ECU does not provide, you can fit the matching sensor and measure the value directly. What you monitor is no longer limited to what the car reports.

*Sensors are optional. Choose the ones you need.

・You want to watch several engine readings at once, without lining the dash with a row of gauges
・Your car is older or modified, or the factory OBDII port does not give you the data you want
・You have modified the car and want to see water temperature, oil temperature, boost and more straight from dedicated sensors
・You want to set up your own screen layout, with alerts and peak recording

Sensors → S-EXPAND expansion box → FD EVO display

The FD EVO can take OBDII and S-EXPAND signals at the same time and show both on one screen. What follows covers the S-EXPAND used on its own, with no OBDII connection. Power comes from ACC and GND only, so older and modified cars can use it too.

Each sensor mounts at its position on the car and plugs into the S-EXPAND. A dedicated signal cable then carries the data to the FD EVO, and the readings appear right on the display. The S-EXPAND has no buttons. Every setting is made on the FD EVO, so the box can sit out of sight near the pedals.

The power connector in the kit gives you 12V and GND. Connect the 12V wire to the car's ACC supply and the unit is powered. This connector is only for power and does not read any OBDII data. ACC and GND supply power only, so you still need to install a sensor for each reading you want to see.

・1 to 6 display fields: each screen can show 1 to 6 fields, and you choose which readings appear, how they are arranged, and which one is the main reading
・Unit switching: metric or imperial
・Voltage display: voltage appears on every screen
・Alerts: set your own ranges. When a reading goes outside its range, the screen flashes and the buzzer sounds, so you don't have to keep watching the numbers
・Peak record (PEAK): keeps the highest value reached on the current screen, so you can look back after a run
・Boost zero calibration: with a boost sensor connected, you can recalibrate zero to the local atmospheric pressure, useful when altitude changes or the sensor reading drifts

These features run on the FD EVO with external sensors and do not need an OBDII signal. The following features need OBDII vehicle data and are not available in this setup:
・DTC reading
・Speed calibration
・RPM and vehicle speed display

The S-EXPAND has six sensor ports for six sensor types. Voltage is read directly by the display and needs no extra sensor, so the display can combine up to 7 readings (7 IN 1). You don't have to fit every sensor at once. Add them in stages to suit your car.

▲Six Sensor Types
Water temp.: coolant temperature changes
Oil temp.: engine oil operating temperature
Oil pressure: pressure in the engine lubrication system
Boost: turbo boost and intake pressure changes
Fuel pressure: pressure changes in the fuel system
Exhaust temp.: engine exhaust temperature changes

▲Matching Sensors to Your Car
Basic monitoring: water temp., oil temp. and oil pressure. For a naturally aspirated car driven mostly at high rpm, start with this set.
Turbocharged cars: add boost to the basic set to watch how boost changes across rpm and load.
Fuel system upgrades: if the car has an aftermarket fuel pressure regulator, add fuel pressure to monitor fuel supply from the driver's seat at idle, in motion and under high load, and on turbo cars at high boost and in vacuum.
Long high-speed driving: add exhaust temp. to watch exhaust temperature during hard driving or sustained high speeds.

▲Reading Oil Temperature and Oil Pressure Together
Oil temperature affects viscosity. Under similar rpm and operating conditions, hotter oil is thinner and flows more easily, so oil pressure tends to read lower. Cooler oil is thicker and flows less easily, so oil pressure tends to read higher. Watching both lets you compare relative changes across different oils and driving conditions, as a reference for how the engine and oil are doing. Actual values vary by vehicle, rpm and oil.

▲Reading Fuel Pressure and Exhaust Temperature Together
Fuel pressure shows how the fuel system's pressure changes under different loads, and exhaust temperature reflects the condition of the exhaust gas while the engine runs.
Monitoring both can help you spot unusual changes under high load, giving you more to go on when judging how the car is running.

Sensors are optional and sold separately. Mounting positions and connector types can differ between vehicles, so choose from the Radiator Hose Coolant Temp Sensor Adapter, the Boost Reference Adapter or the Oil Filter Adapter / Sandwich Plate as needed.

・FD EVO display with mounting bracket
・S-EXPAND sensor expansion box
・Expansion box signal cable (65cm)
・OBD2-CAN signal cable (35cm)
・OBDII-to-DC power connector (12V, GND)

When you use the S-EXPAND with its own sensors, set the signal source once after installation:
1. Enter Settings, change ACC mode to MANUAL, and set the start-up voltage
2. Go back to SOURCE FILTERING and select Control Box
3. Check that each connected sensor shows a value: a circle means a sensor signal is detected, and a cross means no sensor is connected

If you don't need any OBDII data, open the OBDII option under SOURCE FILTERING and switch every item to OFF. The main screen rotation then won't keep showing OBDII fields that have no data.

For 12V vehicles only. Not for hybrid, fully electric or 24V vehicles.

On an older or modified car with no usable OBDII signal, the FD EVO can still run from ACC power with independent sensors.

Actual compatibility depends on the model, model year and configuration, and sensor mounting positions vary with the vehicle and sensor type. Please follow the manual for connections. If you are not sure whether your car can take it, send the make, model, year and the readings you want to monitor to your point of purchase, or leave a message or email Shadow.

  Oil filter adapter/ Sandwich Plate

  ---

  Oil pressure sensor adapter, which can also be called as oil filter sandwich plate adapter, is a kit connected to the oil filter element. This is where the oil circulating filters the oil impurities and can measure the pressure and temperature of the oil. The oil filter element can be divided into general type and paper. The oil adapter is suitable for general oil filter element. Most Japanese models, such as Toyota, Honda, Nissan, Mitsubishi, Mazda, Suzuki, Subaru and so on, use general filter elements. The thread of the oil filter element is divided into 3/4-16UNF and M20*1.5P. The general oil pressure sensor adapter is attached with two specifications of threads. GT86 adapter is higher than the other adapter which have been specially developed for Subaru FA20,FA24(BRZ/GR86/WRX/Forester XT)、Honda L15B (CRV5/CIVIC 10 )、Honda K20C1(FK2/FK8)。In addition, oil pressure sensor adapter have been specially developed for European cars.
