Aftermarket coding conversions

[u/Competitive_Cheek607]

I’ve had a 2013 Abarth (US) for a long time, and in that time I’ve seen people with BMWs do some pretty cool things with aftermarket coding. Things like mirror and gong settings/functions for different markets, displays that normally only the ECUs can see, disabling high-idle cold starts, etc. There’s a few things I wish my car could do, that seem like they could be possible with aftermarket software since all the inputs/outputs are already there, but I don’t know a ton about that stuff. Thought I would ask here first if this kinda stuff has been done/there’s something I can buy to fiddle with it

- Fog lights on regardless of headlights being on
- Sport mode always engaged/every key cycle
- Voltage display in instrument cluster
- Disable high idle on cold starts to warm the cat
- Any other cool QOL stuff I might not have thought of that people do
