Lately I noticed my Exora at idle, fully warmed up, is consuming more than 1.5L per hour, without any aircond alone.
To those who are more technical minded should know that it should idle around est 0.6L/hr. But again this just theory.
Engine load percentage is around 20+ percent at idle.

Here is a video of my RPM and fuel flow rate.
Its underneath the Volt meter and RPM meter.

*New & updated* Idling video: https://streamable.com/o8xu2s
Contains Short & Long Term Fuel Trim gauges

Anyone can share your litre per hour from Torque Pro?
Preferably engine 1.6L and above.

Update:
Earlier I mentioned that "Normal 14.7:1 Air Fuel Ratio (AFR) is 0.45-0.5V. Mine is showing 0.7V at idling , fully warmed up . Richer fuel mixture"

It seems after watching several videos, it seems its pretty normal for it to remain around 0.7Volts

Campro CFE idleat 1.1-1.2k rpm? I thought it should be much lower like 7-800 rpm

Apologies. I uploaded the wrong video. Here is the correct one.
With engine warmed up.

It sits around 850rpm without aircond and gear in P or N.
The video shows 900RPM but that's probably after engine just started.

VW 1.6NA ~ 0.9L/hr with aircon on.

What is the flow rate difference between cold start and already warmed idling?

Maybe ecu preset more fuel pump in to reduce time to get cold engine warm up.

Here is a video of cold start with high idling :

From 2.5L/hr to 3.5L/L, but take into account its idling at 1.2K RPM without touching the accelerator.

Normally ECU for all cars will definitely inject more fuel = richer mixture .
As seen in the video, the O2 sensor voltage (the one with the Graph), is before the cat converter.

Normal 14.7:1 Air Fuel Ratio (AFR) is 0.45-0.5V. Mine is showing 0.7V at idling , fully warmed up . Richer fuel mixture
I will need to check the after cat converter AFR

U done any modifications? If yes send retune etc so your car brain note for your modification

Roughly, Fiesta 1.6NA

0.9 l/hr without AC
1.2 l/hr with AC

this is after warm up

No bro, the car is fully bone stock
Anyhow this is the updated video, with new gauges

Maybe that's what Campros are so thirsty

You can try see who else has CFE for you to do comparison.

Update: yesterday I took out the Mass Airflow sensor,
Clean it with Electronic Contact Cleaner.



After clean, recheck again Short Term Fuel Trim (STFT) gauge, now its better, showing more towards negative %. Meaning amount of fuel injected is reduced to proper levels.

Although it didnt change the Litre per hour, but as much as I search Google for answer to resolution , it shows its not much an issue of this, but rather the STFT and LTFT values is more important.

Next is to clean throttle body but its a PITA to remove the plastic hose from the throttle body. Gonna spray from the Maf sensor hole.

IS it a DBW TB like the IAFM campro? Then spraying from the MAF hole will be very challenging..... most probably need 2 persons to do it

1 to step of throttle and 1 to spray TB/intake cleaner.

Put a stick on the pedal to make RPM stay around 1.5k to 2k.
