We can set in fuel Menu and Chose 4 injector for 8 cylinder. Now the Engine Runs really lean. We Must set Ve to over 140% at idle! Now we change Settings to 40 lbs injectors in fuel menu and See the Engine Runs pretty well with ve 50% at idle! Have anywhere an idea what we make wrong? Hope My englisch is Not to Bad!, thx Arthur
