OK, this is a bit weird, I've made a few changes to the ELM327 startup in carmand which appeared to get my car working again every other try but when I checked the report file my changes didn't appear to be actually there! I'll check what I've done but if you guys hadn't noticed it's Saturday night so I'm about to get ready to go out and this will have to wait.

@makkan00 my guess is that this is a problem with the way Carman communicates with the ELM327 so getting that bit right hopefully will fix these connection problems. If I get somewhere I'll send you my fixes somehow to test
