| You have shown photos of two plugs but not, as promised, of the other two. Why not? |
Because the four plugs are identical. They all have the same condition. Why you assume I'm hiding something? The problem is really annoying me. My car consumes fuel like hell!

You have fouled plugs and don't know if the car is running rich or lean!
In one post you state you are burning oil then later change your mind. In another you complain of black exhaust both suggest worn rings. |
Fouling could be also a result of oil burning.
The exhaust has both smokes, black and blue. I did said that in my recent posts.
During the post, my car has changed the ECU so things got different. It was not smoking black on the old ECU. It sound that you haven't read the posts carefully and you are just throwing out individual comments!

As you don't want to spend £15 and do a basic test, if only to rule that out, don't value my opinion or advice and finally so many others here are offering help I will leave it to them to guide you.
Good luck.

Power is directly related to MEP and thermal efficiency, assuming detonation (pinking or pre-ignition call it what you like) are not encountered then increasing compression ratio increases both MEP and thermal efficiency and thus power at all throttle openings.
If you want to debate effects of compression ratio on power and why high performance engines usually have high compression ratios I suggest we move that to the Performance forum.
Of course one fix may be to fit two head gaskets thus reducing compression ratio, reducing MEP and reducing thermal efficiency yet miraculously increase power. (Joke.)
Ops almost forgot that increasing compression ratio also usually increases swirl and mixture of fuel and air and the higher pressures cause those atoms to whizz around desperate to react with something!

Am I crazy - still offering to help. Your middle name isn't Beresford is it.
So if I assume all your statements are true oil burning can be ruled out and you only problems are low on power, using excess fuel with all plugs equally fouled and black or blue exhaust smoke.
What is your previous and current mpg.
Things to consider /check:-
Low Compression.
Valve timing (belt jumped a tooth.)
Lambda pre or post cat.
Inlet leak.
Exhaust leak pre lambda.
Defective or blocked catalytic converter.
Wrong ECU fitted.
Damaged ECU connector.
New ECU defective.
Low voltage to ECU causing lots of weird problems.
MAP(T).
Temp sensor
Have you had four gas exhaust analysis done since fitting the new ECU.
The order I would check on balance of probability / cost / difficulty for a DIY.
Exhaust leak - free.
Inlet leak - free.
ECU part number check - free.
ECU plug connector visual check - free.
Temp sensor - free and you don't need a meter. With the engine hot and cold pull off the sensor connector and see if the revs change.
Timing belt jumped a tooth - free
Blocked cat - free.
Compression test. £10 for a tester.
Battery voltage, good earths and supply voltage to ECU. £10 or less for a cheap meter.
Lambda - do it with you new meter so now free.
MAP(T) - free with your new meter.
New ECU defective - good luck checking that.
I don't know how you can use excess fuel and pass the exhaust emission unless Egypt has very lax regulations. Get a four gas test done and post results though bare in mind that the cat will be trying to correct any high reading so pre cat reading on a good exhaust is usually higher than tail pipe reading but you probably can't do a pre-cat check.
