OBD-II vs FI+VSS - Request for Comment

[peterj]

dcb: Ok, I'll take your challenge. ;-)

My current development environment for OBD is an Elmscan5, an old laptop running Linux, and PyGame. My goal is to see what can be done with OBD-II data under as many different environments as possible. Basically, I want a SG-II that I can dork around with.

I just spent the past few hours reading over your project and realized the appropriate thing to do is to go back a step and feed the FI+VSS signals into my laptop via the soundport hack so I can actually compare FI+VSS and OBD myself in real-time.

BTW, I have done uC development in the past, and I have complete development environments for PIC (ICD2), AVR (JTAGICE) and SX (Parallex) but since I'm much more of a software guy, I prefer to do my research using perl/python on old laptops before going down to the uC level. (My preference in the past for anything at all complicated has been gcc on the AVRs, and I'm curious how the Audruino environment compares.)
