Ask HN: Where to collab on building automative circuit/software mods?

2 pointsy3sh4y ago1 comments

I'm hoping to find an online community of devs/engineers that share work on hacking their car's OEM electronics across many vehicle brands.

Many small communities share aftermarket circuits (e.g. wranglerforums, tacomaworld, autohack, yodaTeq...), but I can't seem to find a good source for sharing work on building those circuits or sharing the source code.

Types of things I'd like to do:

- Adjust control software of various sensors in the car

- Put optional settings always-on/off (engine-shut-off-when-stopped, adaptive cruise, ECT power, all-wheel-power)

- Adjust the electronic transmission shift points

- Adjust the algorithm for shutting down cylinders

Modifying ECU software is a reverse engineering problem. And a very challenging one at that.

You could start with basic reverse engineering topics and work your way up. Get a copy of your ROM, get it loaded in a disassembler, and start reverse engineering.

The number of people who do this worldwide is extremely small, and most of the good ones do it as a business. They’re not sharing their business secrets.
