The closed loop fuelling has still not been looked at. I had problems with it last year and after a month of fault finding MAxx suggested swapping the ECU and this worked, only for it to stop after a month or so. The first thing I want to do is swap again but the ECU in my sons Fiesta has been completely inaccessible due to the garage being full of BMW 1M panel but slowly they are making their way onto the car.
