I got an OBDeleven for my 2015 GTI so I could unlock stuff and customize. Enabled rolling down the windows with the key fob, being able to display the engine oil temp in the dash and also setting the accelerator pedal curve to linear.
What I didn't even know that was stuff you could even do
The accelerator curve is really cool. A lot of modern cars just have a sensor that detects your pedal position and a simple algorithm decides how much power to translate that into. It's like adjusting the mouse speed on a computer. Feels like you're driving a different car.
Having said that, the default curve is often the best curve. They put a lot more effort into getting it right than you would.
Kinda depends on the car. Volkswagen cars are pretty "hackable" with OBDeleven which is a wireless interface for the hilariously named "VAGCOM" protocol.
Hang on, have I being saying this wrong for years? I thought it was OBDII or OBD2 ?
It is OBD2, OBDeleven is a Bluetooth dongle you plug into it
Almost every car company does something similar and has as long as they've had on board computers.
VW/Audi/Porche are all the same company and generally share the same electronics. A lot of gauges and features are considered "premium" so they just disable them for VW branded vehicles. There's also regional feature lockouts; IIRC North American VW's can't have their fog-lights and headlights on at the same time but you can enable it through VAGCOM.
