It is the injector dead times. Don't use the dead times supplied by ID because they are not correct.

What would be the correct dead times to use with id2000?

The dead times supplied by ID are about half what they need to be.

Start by using the ID 1000cc dead times in the software and then see how the AF changes at very low injector durations when you change the electrical load. You'll need to do a lot of re-tuning since the ID supplied dead times are so low.
