Check out ECUProject.com - some cool stuff is happening over there.
Work is underway now to read (and write) ECU data through the CAN bus eliminating OBD altogether.
Have you seen Tomis site? Good stuff there too, mostly T7.

So even the cars with a contact for CAN on the OBD plug only has access to the same stuff just use a CAN protocol?

when you say Tomis, you mean http://pikkupossu.1g.fi/tomi/tomi.html#?

Are you in the US? I can check out the schematics for the Saab and let you know where the I bus and Pbus signals might be available

Thanks

So if i OBDPro USB Scantool, i still would not be able to have all the control that the I-bus, since my OBD connector does not have CAN on it. But would it work if i add the CAN connections to the OBD plug? Or would i still need to buy something like this
http://www.canusb.com/

Yes I am in the US, and very much will appreciate where i can get the P and I Bus
