Turns out, to change from MPG to km/l, you need to hold the gauge cluster button for 5 seconds. Holding the gauge cluster button for 2 seconds resets the recorded stats. So my idea of converting one unit to the other kind of gets thrown out the window there.
That being said, I did drive around a bit with the gauge set to km/l, though, and never really saw any numbers above maybe 24km/l. 70mpg US would be 30km/l. 70mpg imperial would be 24km/l. So it would seem that there is indeed some setting in the cluster itself to display USA vs imperial gallons, as the readings I got in terms of km/l are more in line with the latter than the former.
The explanation as for why the pump supported the 70mpg as I read it may have just come down to differences in sensitivity for the pump's cutoff mechanism, and the fact that even after driving for 2 hours the difference in the amount of gas used by the car between imperial and USA units would only come out to like .3 gallons. That's the only thing I can think of w.r.t. that.
Frustratingly, after cycling around the display units back to MPG after being in km/l, the reported MPG is more back in line with what I would expect it to look like. So... Have I reset the gauge to USA units again by cycling things while connected to my USA programmed ECU? Am I just driving like an absolute dickhead and getting lower fuel economy? No idea. And like I said, I realistically don't even drive enough anymore to easily make a conclusion. All of this is based off of maybe 30 miles of driving each weekend to do my laundry and maybe visit a local park or two.
At this point, I've just come to the conclusion that the fuel economy readout's main reason for existing is to make me happy. And since bigger numbers = more happy, I'm just gonna take the zen route and accept whatever is shown.
Wish I had a more definitive answer for y'all.
So there was some difference in calculations between Imperial and US units. It would be easier if everyone used the same units of measurement. Oh well. Averaging out fuel economy calculations gives a better understanding of overall fuel efficiency despite differences in variables such as automatic fuel shutoff at the pump. It also shows how other variables such as temperature affect fuel economy. There’s several year’s worth of data from users in the forum Fuel Economy log to browse through and compare your numbers against. Sounds like you’re doing great.

56MPG for the metric impaired. That's US gallons.
Didn't reset the gauge or do any other skumbag tricks to manipulate the numbers. Just hopped in and drove my 25ish km commute. 1/3 in town 40mph or under, the rest "freeway" at 55mph.
Full tank of fuel, 52F outside, almost bald dunlops. Ac off.

I drove like an old lady this morning trying to get under 4l/100km. I hit every red light but traffic was light on the "freeway". I set the cruise at 85kph (53mph). I managed to quickly get the display down to 4.4l/100km on the freeway for a few miles before I had to exit but it wouldn't get lower than 4.3 by the time I stopped. According to the cluster I'll get almost 800km/500 miles to this tank. We'll see about that.
I checked the tire pressure the other day. One is at 42 the rest are 30 something. I'll pump them up to 50 and see how badly they split apart.
I keep thinking that it would have been cool if you could have easily manual swapped your car when you engine swapped it.
So ... mental note to myself. When I start manufacturing cars, I'm going to design the automatics to be easily converted to manual, by adding all the correct structure (holes / brackets) etc. Heck, I think I'll go ahead and throw in the third pedal and associated cable (no hydraulic clutches at 7milesout Enterprises).
However, the manuals will have no provisions to swap to automagic cause no manual buyers / owners ever want to downgrade like that.

Unless you used an engine/trans harness and computers from a donor car along with some or all of the dash/interior harness. Anything is doable but it'd be far easier, cheaper and quicker to just go buy a 5speed.
Keep in mind, these things often run like poop and throw abs codes if you have a burnt out brake light bulb.
