I wouldn't get excited by BMW maps, yes they are complex (which is why no one ever actually remaps the physical map), but the quality of workmanship is awful. Rough, overly lean, a quick bodge disaster to get it running, is far closer to the mark. Yes, they pretend to care about emissions, but you could see for yourself with a power commander and an afternoon playing with your laptop "guessing at the mixture settings" would actually give a far smoother, more powerful, better and safer map.
However a PCV is just a joke bodge too. What I now believe is going on with most "professional remaps" - (the next stage on from PCV bodge) is messing about tweaking the spare bit on the stock map designed for "adaptions".
Adaptions are stored extra tweaks to software on modern vehicles. It works by adding a new layer (and thus minor changes) to the stock map, based on learnt fixes, refinements and workarounds for poor sensor data, wear and tear and cheap manufacturing at build. These enhancements (AKA adaptions) are based on how badly its running and tiny modification to individual ignition and fuel maps per cylinder to help make it less bad.
What we get these days is new bodge on tuning shops (who aren't prepared to pay for the software and checksums to do it properly). So they now over egg the adaption data to bring a bit extra to the party. Best seen where a turbo can be wound up by the stock map. Its also why so many are "not seen when plugged into diagnostic equipment…." nothing had been reprogrammed - most are just livelier assistance from the systems own engine management !!!
These guys appear to write the original BMW maps https://www.evc.de/en/product/ols/software/
I came across it hacking a copy of the stock map the bike came with using a hex editor.... turns out the stock BMW maps contain these guys info. I'm only looking because my R1200GS got a software update by BMW and it ended up much slower.... Smoother till 4k then flat and useless afterwards.
I think this is the same brentuning mapping at 1/3rd the cost https://www.remapper.co.uk/buy-remapper/
and in reality its just playstation tuning. Buy this, the computer says these settings work - now give me $800. The reality is the Chinese box is worth less then $40 and the map software is worth about 3 cents - its just computer generated crap.
Sadly these guys don't touch the overly complicated (for no good reason) maps BMW and KTM dabble with https://youtu.be/9WYjZrpa-ZU

Don't forget the PCV for the K1300 only bodges the fueling (unlike some, this bike doesn't get any ignition tweaks) and can only work after you disconnect the Lambda sensor. So it reverts to the stock BM map and adds or subtracts tiny amounts of fuel based on a map you can write yourself. I know the old UK importer of this gear and he thinks the autotune is a joke and is really only for people desperate to play who have zero access to a dyno. If you want the auto tune to build a good map you need lots of time and a set of progressive hills, then go up and down thousands of times on every load and throttle setting you can imagine.
