I am not trying to hijack the thread, but for the subaru guy, there are plenty of opensource development like romraider www.romraider.com that allow you to connect to the native subaru protocol SSM instead of pure obdii. this allow you to make faster readings over more engine values in the ecu.The thing is that is java, I have manage to make it run with ejre1.6 but the rxtxcom libraries are broken. anyway the good thing aboyut their developement is that is parametrized in xml files, so probably that could be used in carman.
