Well, since 101.04 and 101.05 cars are identical hardware wise, the 101.03 car differs by water spray on the intercooler and 101.03 and 101.05 have identical maps, I suppose the ECU dislike it having the wrong chip and goes into grumpy mode.

To further elaborate on the differences, the water spray doesn't do more than a high velocity would do to the intercooler. There is nothing in the ECU that needs to be changed to cope with either of those hardware configurations. It is all there, in both of them.
