Ask Slashdot: What's the Most Hackable Car?

An anonymous reader writes: When looking for a new (or used) car, I have readily available information regarding features, maintenance history, and potential issues for that specific model or generation. What I would really like is a car that is readily hackable on the convenience-feature level. For example, if I want to install a remote starter, or hack the power windows so holding 'up' automatically rolls it up, or install a readout on the rear of the car showing engine RPMs, what make/model/year is the best pick? Have any of you done something similar with your vehicle? Have you found certain models to be ideal or terrible for feature hacking?

Which part?

The Mitsubishi Evo and Subaru WRX probably have the most hacked ECUs around. Loading something like ECUTek onto a BRZ or FR-S gives you equal control. Convenience systems are usually controlled with some kind of aftermarket device, though for Toyotas, you can download Techstream and control a few options via a cheap cable off ebay. A Tesla offers the most toys to play with out of the box, but you can't do a think with the actual drive system. An M-series BMW like an old M5 will give you loads of settings to play with between the engine, transmission, and suspension.

BMW

Most of the BMWs from the 90's onward are fairly hackable. You can find copies of the dealer software and production line tools on the web, and tools like NavCoder and similar allow you to control tons of the "convenience" features. Most of the modules have had their options decoded by interested individuals wanting to customize their vehicles.

Some info here.

Not sure about most hackable, but...

The BMW E46 (3 series between 1999 and 2005) and other BMWs from that era all use an in-vehicle network called "I-Bus" which operates things like the windows, the sound system, the lights, and more. Most non-critical vehicle functions are exposed there and are fairly well documented by the community. You only need an inexpensive adapter that looks like a serial port as far as the computer's concerned to access it.

IIRC the first generation or two of Mini as well as a few Land Rovers of the time that used BMW engines also have I-Bus.

Newer models have an optical system called MOST running the infotainment system, I'm not sure where the windows and lights are connected in these days.
