Thanks.
Now how was that 48 km distance determined? ... a car in dash trip meter , google maps , rough shoot from the hip guess ... ???

I'm not expecting you to have done anything ... you asked in post #500 for explanations... I'm just trying to better understand what did and did not happen in order to offer those requested explanations.
and you also asked what else people would want to know ... which also fits well into my asking questions about what did and did not happen.
As for the speed ... locked into a set speed +/- 1 kpm or so is not needed ... it much simpler and easier than that ... Distance / Time = Average Speed.
If it took you 30 minutes to travel 48 km than you had an average speed of 96 kph.
Ideally we would include any +/- from the accuracy of the measuring devices ... so if you could have been 47km or 49km that would be a +/- range of 1km on the distance ... if your time measurement could have been 29 minutes or 31 minutes that is a +/- range of 1 minute ... meaning you would have a speed accuracy range of a window ... as slow as ~91 kph ... to as fast as ~101 kph ... a +/- of about 10 kph just from being +/- 1 minute and +/- 1 km.
What the average speed was for each trip can have a significant influence on the energy used ... the slower you travel the less energy it takes... thus the less fuel it takes.

Did both runs have the engine equally warmed up into its preferred operating temperature window?
It is well known that a colder engine is less efficient than one that is warmed up into its operating window.

Nail on the head.
That is the elephant in the room for many people.

And why the question becomes as you wrote in post #500 about what is the cause ... as Old Mechanic listed some of the possibilities of it as an alternative to other maintenance and tuning ... If the results are no better than the tune up and such that he recommended than it just becomes a comparison between the two options ... which is easier, cheaper, more durable, etc?
You did make claims about experiencing a change in your fuel economy from 8.8 km per L to 6.2 km per L ... and you seemed to be atributing that change to the HHO system.
I still haven't read how you determined the amount of L of fuel used over those 48 km ... ??? ... that is another potential answer for you.
For example ... The OEM fuel tank capacity of my car is 10.6 US Gallons ... but there have been people who have put over 13 US Gallons into that OEM tank ... if I were only using a gas station topped the tank off as a method of measuring how much gas had been used ... I would have to keep in mind that there is a significant potential for very poor accuracy from that approach.

To sum up ... in regard to the question you asked in post #500 about what else we might want:
I would still like to know the method of determining the 48 km?
What is a reasonable +/- confidence in that 48 km?
What was the average travel speed for each trip?
What is a reasonable +/- confidence in that speed?
Was the engine equally warmed up for each trip?
How was the quantity of Liters of Fuel measured for the 48 km trip?
What is a reasonable +/- confidence in that Liters of fuel measured?
- - - - - - -
To sum up for you request for explanations about what happened ... You already have some potential explanations for the results ... and with more details ( like those still open questions above ) ... other potential explanations can also be offered.
