VP37 Pump Tester

Introduce:

EDC(Electronic Diesel Controller)- VP37 Pump Tester

The repair tester for BOSCH VP37 pump simulates the outputs of an Engine Control Unit (ECU), to control fuel injection quantity by driving the proportional rotary-magnet actuator. The injection quantity consistency under different engine speeds or different fuel injection deliveries can be tested by this tester.

Design Features
1.Two user selectable operational control modes
 - Open-loop control mode
the angular position of the rotary-magnet actuator is controlled by manually setting the duty circle of the driving PWM signal.

- Close-loop control mode
the operator sets a target position of the rotary-magnet proportional actuator. The system adjusts the duty-cycle of the driving PWM signal automatically according to the real-time measurement of the angular position sensor.
The proportional actuator is stabilized to the target position quickly.
2. Monitor voltage signal of the angular sensor on the LCD screen
3. Button to enable or disable fuel injection cut-off solenoid on VP37 pump
4. Calibrated by a Bosch Genuine Standard Injector

1. General  Introduction:

VP37 is an indispensable electronic control instrument to test function of rotating pump, EDC is electronic fuel injection system for small and business car, for example AUDI, BMW, FIAT, ROVER, BENZ, BORA, JETTA, ISUZU and HAUTAI etc.

VP37 is a complete digital device , can test parameters of rotating electronic control pump according to standard parameter from manufacturer.

There are two ways for Electronic Distributor Pump Testing, Static State and Dynamic State.

1)      Static State: Connect lines of distributor pump with VP37, and measure by multi-meter according to data from factory, to identify order of all line connection suit factory standards.

2)      Dynamic State: Control rotary electronic pump working by VP37 signal, at the same time rotate electronic pump output signal and display on VP37.

VP37 equipped with alarm light includes output short overload, to find and solve problem.

2. Button Instructions:
This system total include 7 buttons, 3 of them are function button ( switch, export, out), and the other four are menu buttons ( speed, temp, ↑and ↓)

"Switch" button is used for changing the cylinders, the default setting is4-cylinder, and the signal light is off. If Signal light is on, it shows 6-cylinder.

"Export: button is the controlling and output key. This button can control the rotational electromagnet voltage of VP44 PUMP, signal light effective. (When rotational speed stability or above 100 rpm effective).

"Out" 12V voltage direct output button, and the signal light effective.

"Speed" shows the rotational speed of test bench. When press this button, the window light and rotational speed effective.

"Temp" displays the current oil temperature, press this button, the window light, and display the temperature. Press the button "Speed" and "temp" at same time, light display window show the advance angle, it can set the advance angle through up and down button ("↑" "↓"), and the biggest advance angle is 60'. It can change oil pump injection time whiling changing the advance angle.

"↑"and "↓" button is increase or minus button. It can change the PWM value and advance angle.
Note: When right display window show advance angel, it couldn't set the "PWM" value.
