What kind of display screen does this use? Can the backlight color of the display be changed?Answer: Use a low-power LCD display screen. can.2. Can the speed unit be changed? KPH, MPH?Answer: Yes. The multi-function racing car modification table can switch between KPH (units per kilometer per hour) and MPH (units per mile per hour).1. Can the pressure unit be changed?Answer: You can switch between BAR/PSI units in the multi-function racing car modification table.2. Can the temperature unit be changed? Celsius, Fahrenheit?Answer: Yes. The multi-function racing car modification table can be switched between Fahrenheit () and Celsius () units.3. Can be used on motorcycles?Answer: Suitable for all 12V vehicles, and has the function of life waterproof, which can be installed and used on motorcycles.4. Is this model equipped with all sensors? What is the sensor thread size? Can the sensor of the original car be connected?Answer: We are equipped with oil temperature sensor, water temperature sensor, oil pressure sensor, turbocharger sensor and exhaust sensor sensor with uniform thread size ZG1/8. Therefore, the original car sensor cannot be connected, and the original car sensor needs to be replaced with our sensor. Otherwise, the thread does not match and cannot be installed.5. What should I do if my vehicle does not have an ECU?Answer: Usually the signal needs to be connected to the sensor, and the speed and vehicle speed need to be connected to the ECU.If the vehicle does not have an ECU, the speed can be connected to the negative electrode of the ignition coil. At this time, a speed adapter (sold separately) needs to be installed, otherwise it is easy to be interfered by the speed. Some customers want to connect the speed signal to the crankshaft sensor, we do not recommend installation. Because the pulse signal of the crankshaft sensor is much higher than the ECU output, the speed signal will be inaccurate.Connect the Hall speed sensor to the vehicle speed, and then perform the vehicle speed calibration according to the instructions. The vehicle speed sensor can be installed on the front or rear wheels. Other signals are still connected to the sensor and will not be affected.6. How to receive the air-fuel ratio signal? There is no air-fuel ratio sensor inside.Answer: The air-fuel ratio signal is directly connected to the narrow-area oxygen sensor (0-1V) of the original car, so we do not have another air-fuel ratio sensor.7. Why is the vehicle speed always showing 255 when I installed only?Answer: The vehicle speed keeps showing 255, which is most likely caused by low-speed calibration. Please re-calibrate the vehicle speed according to the instructions. Vehicle speed calibration requires the vehicle to drive to 40KM/H, and then press the confirm key. If the vehicle speed is too low, the calibration will fail, and the vehicle speed will display 255.8. There are several spare sockets on the sensor converter. Can I use them to connect other data?Answer: No. The spare socket on the sensor converter cannot be used for other purposes. This is because the converter molds of 904/907/908/909 models are the same. The free sockets are reserved for the combination tables of other models.9. Why can't I read the speed after installing the multifunctional conversion meter?Answer: Usually the speed signal can be connected to the ECU. If the v
