Lpg ecu.

How can I look up for EG software??
Ok it is EG Oscar n plus.

 

[KeepItSimpleStupid]

Should the marked points touch repair wire??

I suspect not.

The third pin down on the right of the edge connector looks like there are 3 wires branching out. This looks suspicious.

the right point you circled has a thermal relief or 4 traces in a + pattern

Good question !
I suggest you contact EuropeGas Tech Support at serwis@europegas.pl .. ..include a picture of the label on your ECU and ask them to identify the ECU and which software to use .. ..
You will also need the correct interface cable to connect your ECU to a computer .. .. .. .

Here is the news .. .. .. . !

Go to www.europegas.pl .. technical support .. software .. scroll down to Oscar N plus .. .. click on 'download'

It is the yellow condansator on 2nd pic.

It does not look like they should be in contact with the trace you repaired.

Is it possible that I grounded the ecb while trying to measure if relays were open as the car was running??
Because now even petrol is running so bad I guess some cylinders are not working.
And on lpg the power is waving like you are closing and opening the throttle. Musicmanager

What is this???
Sorry but I could not find exactly.

Who knows ? Impossible to answer !
One thing though, it is most unlikely that anything to do with the LPG ECU is affecting the engine running on petrol. Easy way to check .. unplug the LPG ECU and run the engine on petrol .. .. if symptoms persist .. .. ..

And on lpg the power is waving like you are closing and opening the throttle.

That sounds like the engine is 'hunting' .. usually a problem caused by the Throttle Position Sensor - often on the back of the Air Intake of the manifold .. .. .. it's unlikely to be a faulty Sensor because it would be behaving the same on petrol, but it's an electronic device so you may have a connection problem with the LPG ECU, perhaps related to the damaged track.

You should consider that each time you've attempted to repair your problem the result has actually been worse than when you started. I strongly recommend you get some professional help.

I believe you will certainly need to replace the LPG ECU and then use the diagnostic software to find the solution. Oscar N is very straightforward to use; but I also believe you have some other more fundamental faults such as plugs, plug leads etc which are contributing to the issues.

EuropeGas used to offer calibration and diagnosis via remote connection to your computer. I don't know if that service is still available or indeed, how secure it may or may not be, but if you cannot find a capable technician in your locality it might be the only option.

Yes trying to measure while running was an error
It was fine before.
I hope It didn't affect cars ecu.
I already found a replacement ecu.
I thought lpg ecu must be connected even to run on petrol. I will try definitely. Thanks Musicmanager

 

[Umitbat]

Nope did not start lpg ecu disconnected.

sorry, MM being thick !
Disconnecting the LPG ECU would switch off both fuel solenoids, of course it won't start !

I think there is a miscontact on the repair because it runs well sometimes

 

[Umitbat]

By the way soldering paste is really disturbing!!!!

 

[Umitbat]

One last question please....
The photo is before damage.
Wondering if those pins are connected to trace.
Is it likely that left one is??

 

[KeepItSimpleStupid]

I think no. I think I see thermal reliefs https://en.wikipedia.org/wiki/Thermal_relief on both pads.
The left middle pad in the pic on wikipedia shows a thermal relief clearly.

 

[Umitbat]

I think no. I think I see thermal reliefs https://en.wikipedia.org/wiki/Thermal_relief on both pads.
The left middle pad in the pic on wikipedia shows a thermal relief clearly.

The one on the right is definitely thermal relief
Left one is normal.

 

[KeepItSimpleStupid]

The left one "could have" been connected to the trace. It's open on the trace side. Is it possibly a pad by itself connected to your trace?

 

[Umitbat]

Since I found a bargain replacement ecu I decided to connect pins to trace.
First I connected left one which resulted as it started fine on petrol but after lpg kicked in both got lumpy.
And then I connected the right pin and lpg light went off and lpg never worked again so it stayed on petrol.
But petrol is working fine so thank God I wasn't successful at harming cars ecu KeepItSimpleStupid Musicmanager

 

[Umitbat]

Can u please identify the marked components?
Circled little component has contact BTW upper and lower left leg so it's busted.
The leg shown with arrow of the other component looks burnt and it also has contact where as the other one has not. So they are two defect components I found...

 

[Umitbat]

Oops sorry I guues they can be many things in same shape.
