ECU got the EU has to cut fuel + - 1bar, what happens when you let go there more? I have a fuel cut defender. ECU'll let a lot of gasoline? Should I buy a wide band O2 sensor, right?

sorry for my english

If your FCD is set for 1bar, anything over that the ECU will keep pumping in fuel as if it was at 1bar.

That will be ok for a few more PSI (maybe 16psi) until it does start running out of fuel and leaning out.

Having a wideband 02 is a VERY good idea, as they you can be sure you are not leaning out and going to destroy the engine.
