Okay bro, i am not sure if this OBD2 Works with 2003 Model or not.
Bro i am not 100% PRO in readings , i use this forum to get the Readings answers, you can also use youtube to learn more about the Right readings.

Main things are Fuel Trims, Short and Full trims,
o2 Sensor Readings
And others RPM

Torque app is working on my civic but the interface isnot understandable to me as the pics you shared here are much easier tomorrow i will check this app compatibility with the obd tool

I have bought the obd 2 car tool to check the readings of the sensors as my car is not giving its prescribed fuel mileage for your info i have Civic 2003 exi manual on petrol it gives me 8-9 kmpl with AC in City and 12-13 kmpl on highway with AC. I have changed all the following things

Spark plugs
Fuel filter
Fuel injector
Tires changed to 195/65/15 with alloys
Radiator serviced
Fan is on auto
Tappet also adjusted
Throttle body serviced
Pcv valve changed
Air filter changed
Oil using now 5w30 earlier was using 20w50 but still was getting same fuel mileage so no change from this side.
Tire pressure equal in 4 tires
Alignment done
CNG was removed earlier but still mileage is not good.

I am sharing screenshots of the sensor reading please guide me that is every reading is in good shape or not in both cases in ideal and in moving conditions.

I see that the timing advance is fluctuating rapidly and goes even to 0 degree and keep under 10 in ideal then reading sometimes exceed to 40 then fluctuate between this

This is the max you can get it from this model

@xulfiqar Because 0% would mean throttle position set to completely closed, no air intake and hence rough idle/shutting off the engine?

Mine is set at 16% at idle with operating temperature 70°C plus.

Which connection profile you're using for Honda?

[Hassan1991]

Check where it goes at wide open throttle.

[xhaikh1]

Car scanner app
And obd elm 327 tool

[ahmedstudio]

Mine goes up to 85% up on wide open.

I am ready using this setup. I am asking about the OBD connection profile for Honda Civic (you must have set it up while adding you car in the app). Kindly see the connection section in settings and share the profile screenshot. Thanks

What car do you have and whats its fuel consumption??

[ahmedstudio]

Toyota Belta 1.3 Litre 2SZ-FE engine, Model 2008
12-13 km/l in city with AC
16-17 km/l on highway with AC

I have already shared the fuel trims here

Right, with iridium plugs, I do feel great response while accelerating with aggressive foot. By the way here is some data. LTFTs here are learned values after a 60km run on highway. IDLE [image] 2470 RPM [image] 3547 RPM [image] @Hassan1991

[Hassan1991]

Seems fine to me.
