Civic 2000 D15Z6 engine swapped (Many issues)

[hasankhurshid29]

Ignition timing already seems advanced by a great amount, look inside the red circled section below

He didn't fiddled with it. It is like this for a long time. Can it be that the correct timing is at that location because of some other thing is offset?

Today I again tried the obd2 scanner and it didn't work. Tried pin15 also. But still it didn't work.

If the connections are right and correct protocol is selected from the app then it means your obd device doesn't support K-Line communication protocol.
I told you earlier, these cheap ELM 327 clone chip based scanners don't support all the listed protocols.

Moreover, It will never work with pin 15 as this pin is meant for L-Line communication protocol.

More likely this is the issue but I don't think It is wise to spend money on elms.
Also ancel icar2 is more likely work as you were saying because I seen on there website that it is based on original elm327 chip.
Now I will be getting hondash Insha'Allah.
The biggest reason is to get the coolant temp reading and warning if car starts overheating. Did you keep your hondash attached all the time?

[shabbir.1]

Yes, it remains attached all the time. I have run a separate wire from switched power supply circuit of the car through an external fuse to power it. Now whenever ignition switch is put in ON position the scanner gets its power and automatically connects to phone or the android dash panel.

Does you low fuel light on cluster works properly?

[hasankhurshid29]

So today my cng mechanic cleaned the throotle body and cng kit. Now my problem is that the rpm are too high around 1500 on idling when engine is warm on petrol and cng both. And on cng it is giving vss error code whereas speedometer is working.

[hasankhurshid29]

Should I perform this?

[shabbir.1]

is there any gasket present behind the TB or your mechanic has used silicon for this purpose as one can see silicon residue everywhere.
If the throttle cable has no tension in it and the idle adjust screw is not fiddled with, then there must be some air leaking inside the IM.

[shabbir.1]

This screw is sort of fine adjustment, if the RPM is out of range by a great amount then this screw should not be touched.

Either throttle plate is not sitting at the right position or there is some air leaking from the TB mating surface with the IM. The mechanic hasn't fitted ir properly.

Before putting back the hoses all silicon residue is removed and I don't know about the gasket present or not but idle adjust screw was fiddled by me and some other mechanic many time before this throttle cleaning. But last time I try to set it, I couldn't increase or decrease the idle (I think at that time car was not having auto fan)

The rpm is around 1500

[shabbir.1]

When the engine is running put your finger on this screw and check if you feel air sucking inside, RPM should drop when you put your finger firmly over this screw.

Check the gasket behind the TB it has to be there otherwise air will leak inside and you can't do much about it. Also check the o-ring beneath the MAP sensor it must be soft and of proper size.

[Hassan1991]

set the rpm from the screw.
vss should also be connected to ecu. check it is connected or not.

[hasankhurshid29]

Nothing happens when i tight or untight the screw and i can see the gasket behind tb.

@shabbir.1 @Hassan1991

[hasankhurshid29]

vss should also be connected to ecu. check it is connected or not.

If not connected how speedometer is working

[hasankhurshid29]

I have checked the vss harness and it is connected

[hasankhurshid29]

Remove iacv grip and then check rpm. Also reset the ecu by removing battery terminal for 5 minutes. It should idle at 800rpm.
