Fuel Consumption Signal - REVELTRONICS UTCOMP-3 User & Assembly Manual

etc. For outside temperature sensor we recommend to place it ahead cooler in a low place or at the bottom of side mirror. The correct placement of
sensors is a key influence on subsequent accuracy of the actual temperature.

2.4.5. FUEL CONSUMPTION SIGNAL

Injector control signal (PWM) or dedicated fuel consumption signal (PWM/FREQ) connect to pin A10. There are few places when you should looking
for these signals - it depends on engine type:
Petrol engines:
•
option 1 : directly on the injector connector – two pins should be in there (or more in case of mono injection). When the engine is ON, one pin is
+12V constant signal, the other one is pulse signal 12V...0V (PWM injectors GND controlled). Pulse signal should be connected to pin A10 of
UTCOMP (sample waveform is shown below),
•
option 2: to the appropriate pin in the ECU connector (injector control) - pinout for ecu connector can be found in electrical documentation
(wiring diagrams) of the vehicle
