Goods: 2.5 inch colorful car tuning meter DEFI
Size: 2.5 inch (equivalent to 60MM), table thickness of 44mm
Color: red, blue, ice blue, yellow, warm white, purple adjustable
Material: With table, with sensors, wires
Function: with self, alarm function
Type: tachometer, voltmeter, oil temperature meter (to be equipped with cake), oil pressure gauge (required with cake), water temperature (required temperature with tee, tee size temperature owners need a friend to confirm), vacuum gauge, turbo pressure gauge
1, the installation tachometer is 4,6,8-cylinder models need to install the (other tables all common);
2. Install oil / oil need to install additional automotive instrument adapter seat (cake), install both tables need only one cake;
3, install the water temperature need to add water temperature tee connection (other styles meter can be installed directly).
First, the voltmeter: the so-called voltmeter, of course, is to measure the voltage of a car battery, this meter installation is the simplest. Two power lines, two lights. Then the power of positive and negative on OK.
Second, the water table: When installing the water table from the tee screw on a ground connected to the vehicle body Ground water temperature.
Third, oil temperature meter / pressure gauge: After installing oil temperature or oil pressure gauge, the pointer to the top down, the same need to take on a ground sensor to body Ground of.
Fourth, the tachometer: Tachometer installation is relatively simple, normal is two light lines, two needle, usually red to positive, black to negative. But the only difference is that there are signal lines connected to the find places. Where the signal line can be connected to it, in general, there are three-connected car:
1, can be connected to the ignition coil negative (negative ignition coil wire), tachometer is based on magnetic principles work, he can receive the very beginning of the ignition coil current thrust generated when a pulse signal, and this signal is converted to turn the displayed value. The greater the number of revolutions of the engine, the more pulse generation, transfer values shown in the table will be.
2, can be connected to the signal line on the crankshaft position sensor on the. Truck models of different structures on the crankshaft sensor used also different. Separable magnetic pulse, photoelectric, Hall of type three. He usually mounted on the front of the crankshaft, camshaft front flywheel inside the electrical or points. Two lines is generally magnetic pulse and photoelectric signal line connected to try to clear. Three lines on the Hall-style, a supply line mostly red -5V ,, a black line negative, and the other is the signal line. (There are four lines, with the exclusion of the other part of the vehicle interference.)
3, now mostly a collection of automobile car engine revolution number signal, ECU circuit diagram can be found the original car computer, make sure your car’s original revolution number signal from which pin out, then the signal line connected to its output on OK.
