I have noticed that engine braking is totally different in that car - tiny engine with smaller compression ratio...

This is the thing I am finding tricky. In the TDI the relationship between fuel used and the throttle is linear, well with an effect for engine speed, but more or less - foot down, more fuel, lift off no fuel. As it's fuel controlled that makes sense.
In the small petrol there is less of that relationship, from observation anyway. I am using my DFCO trick more and more though, and hopefully 1st bar on the gauge at 140+...
