More speculation, you have no idea what savings, if any, the update has on any of the vehicle's emissions, no-one has because MB don't have anything to say about it, and until they do, I for one will be running update free and driving with moral and legal integrity.
there will be a few big reasons they don't disclose how they build a map.
1) intellectual property
2) to put it in to words would be very boring, very complex and expensive
3) the fact you wouldn't understand it
to suggest you got the world's best map 6 years ago is quite frankly ridiculous
a) almost certainly it will have been rushed out in time to get some sales revenue coming in, within the next 18 months there will have been two or three minor updates for drivability issues that engineers subsequently found on their own or from feedback in various markets
b) its quite likely in the early days there were further tweaks for emission / cold start / extreme weather situations others picked up
c) these days very likely other small tweaks to correct oddly behaving engine temp read out, or wobbly fuel computer readings
d) logic fixes for bugs in the alarm and immobiliser as later better ideas were understood
e) stupid numbers of tweaks, fixes and changes to TRY and get the DPF to behave itself
f) EGR tweaks for things like engine temp during start up and poor interior heater performance
g) Engine cooling fan trigger points
h) Gearbox and cruise control performance
i) interesting extras the CEO now thinks should probably be removed before he goes to jail
j) security enhancements
k) improved diagnostic capability. As certain components misbehave and dealerships struggle to resolve, the factory will realise further diagnostic information built into the engine map make solving them simpler / possible
l) make it legal and pass the test it was supposed when first sold... which when they wake up and fix our MOT will mean it has a chance of passing
so when someone offers these for free - it would be a great idea to say thank you
AND DRIVE OFF IN A FAR BETTER, MORE RELAIBLE, SAFER AND LEGAL CAR...
one bit people forget is after a significant change it will have had its adaptions wiped out. Over the next 200 miles or so the car will settle down and get better to drive - closer to how you remember - as it adapts to suit the manu tolerances yours has and or the wear and tear of your particular vehicle
