Hi, Flying Eagle, and thank you very much for the approval and the answers. I'm sorry I posted 2 threads but I thought something is wrong lol.
I have a Euro spec 4G67, compression ratio is 10.5:1 and the compression pressure is like 13bar on all cylinders.
My old ECU was bad and I bought another one from Germany, which was never opened. The first thing to do was to change the capacitors and then I put it on the car.
About pulling the cables - I know its not the best method for diagnostics but it's simple and it works. There is something wrong with cylinder 1 and 2. When I turn off the injectors from the logger I have the same issue so I think this might be the problem, not the spark plugs and cables.
I forgot to mention that I have a LPG system mounted on the car. When I disconnect the cables running on LPG its even on all cylinders so I guess I have bad injectors. I bought them from the same DSM I got the CAS and they worked for a couple of weeks, but nevermind I will inspect this later. I think its not related to the ignition problem which is observed both on LPG and gasoline.
Also, everytime I move the CAS I ground the timing plug and the diagnostic plug inside - as its written in the books so I'm aware of this.
I don't have a timing light so I'm doing it "on eye". I know its not a good method either, but... Not quite sure how correctly the logger shows the timing though. Fact is its showing moving in the opposite direction and it feels like it. Lastly I ran at around 10deg BTDC and it's a little bit better, but still is moving at the opposite direction and I can't understand why. It does it with both ECUs so I think its some kind of a sensor problem, maybe? I presume the CAS is good as its from a working car, the cooling temp sensor is new (I read somewhere it affects timing); I'm searching for a 6pin MAF, but no luck for now. Also, a colleague from Russia said I should check the knock sensor, and I should do this in the next couple of days.
All ideas are welcome and thank you very much again.
