I have a doubt regarding the values that are presented in MPGuino, which is when I stop the displayed value on instant FE begins to increase until it disappears, is this normal? Or have something that is not right?
I leave here one video a bit bouncy, but is not easy to conduct and record at the same time.

Yep, it is normal to have your instant fuel economy value increase until it disappears, when you stop. You can check the instant fuel economy value by taking your instant speed value, multiplying it by 100, and then dividing it by your instant fuel rate value.
So, for the case for just before the instant FE disappears, it is displayed as 184.55 L/100km. The instant speed is 2.5 km/hr, and the instant fuel rate is 0.63 L/hr. Taking these values, we find that the instant fuel economy is actually (2.5 * 100) / 0.63, or 396.8 L/100km.
In this case, the displayed instant fuel economy value is actually lower than it should be, and that's due to the window filter code that smooths out the display values. So - this is normal.
People that use US units, instead of metric units, will see their instant fuel economy value drop as they come to a stop.
That's a pretty cool display, by the way. I like the black background with white dots.
