Behold: The Car Kracker!

[tk-421]

This looks like an awesome project: http://www.gadgetgangster.com/news/54/556

A few quotes from the site:

Want to unlock your car door with your phone? Re-map steering wheel buttons, or log performance data? The Car Kracker an open-source addon for your car that lets you;

• Add an Aux-In or music jukebox
• Remap steering wheel buttons
• Remove the Nav warning screen
• Display text like emails and SMS on your Sat Nav, radio, or dashboard
• Access engine and performance data like air/fuel ratio, oil pressure/temp, and VANOS
• Code retrofit parts like rain sensors, run-flat tires, theft alarms, and keys
• Access the proprietary error logs to troubleshoot engine, transmission, or accessory problems.

You can also upgrade Engine / Transmission firmware, remove the speed limiter, reset warning lights, and change dealer settings.

Looks like it will work with any car compatible with ISO 9141 standards (including Toyotas), but I can't find any specific information on our cars.

Does anyone know if the Yaris is compatible (*cough*CTScott*cough*)?

ISO 9141 is the old (pre 2006 for Toyota) OBDII communication method.

Bummer. Any chance that it could be tweaked for our cars?

ISO 9141 is very simple to interface to. It only takes a transistor for the hardware interface and some simple serial communications for the software side. Our cars use the CAN Bus standard ISO 15765, which requires a significant amount of hardware and software to interface to. This is a big part of the complexity of my YarGauge.
