Yes, that's the big question for me now isn't it - full bitrate.
I've been learning my stripes using an ELM327 based unit and am constantly hitting buffer overflow - even at 38.4k. Looking at the chipset I it appears that even the USB versions run at slow speed too - and certainly not at full USB 2.0 or even USB 1.1 speeds.
But as a tool to get me started and learning manual commands and reponses via Hyperterminal I have found it useful.
Even your OBDPro tool at 128kbps would struggle to capture a full-speed PCM reflash. Or do you have a more positive experience to report?
I'll post another thread Re: available scantools that can sniff a CAN bus at full rate.
