Does anyone know if there exists opensource Tuning software created for viewing, logging and tuning of Engine Control Units ?
It should support these Bus Protocols:

* CAN/ISO 15765/GMLAN
* 2nd CAN (Dual or Single Wire)
* Ford SCP (J1850PWM)
* GM Class2 (J1850VPW)
* KWP2000 (ISO9141/14230)
* Chrysler SCI (J2610)

I know about the scandaq device, but shelling out 2995US$ for one is not an option.
