I hate to say this but i suspect its the injectors (maybe 1 or multiple) i was getting all sort of strange engine live readings--can your garage put a bore scope down to see what the injector tip looks like? mine showed two injectors very wet.
whilst the engine is under temp it will run conventional injection profile but once hot it will enter ultra lean and this requires a very accurate petrol mist at exactly the correct time.
It in my opinion is very unlikely to be ecu and that was one option with my car so i got an other and had the security chip swapped over. At no point did it ever have a code to hint injector issues. Good luck mike
