Protection class :
Application:
Fuel pressure emulator has been designed for cars in the case of which,
there is a pro blem with
excessive pressure on the fuel rail while the engine
is running on gas.

Fuel pressure emulator is also compatible with other cars
(not included in the above-mentioned list), provided they are equipped
with a sensor monitoring fuel pressure on the fuel rail (mainly FORD group engines).
Operation Principle
While the engine is running on gas, as the fuel in not being collected from the fuel rail,
gasoline pressure increases above the nominal value. As a result the gasoline
computer reduces injection time (or / and reports a defect).
Fuel pressure emulator solves this problem – while the engine is running on gas,
the device emulates correct pressure readings and thus prevents
the above-mentioned issues.

1. Identify signal wire of the fuel pressure sensor.
2. Measure the voltage at the output of the fuel pressure sensor using
a multimetre while the engine is running at low revs (and running on gasoline).
3. Supply the Emulator prior to installation in the car (blue wire: +12 V, black wire:
GND), use the potentiometer to set the initial output voltage
at the value measured in item 2.
4. Install the device in line with the diagram.
5. Start the engine and switch to gas.
6. Adjust the Emulator output voltage if necessary (while the engine is running on gas).
