I'm sending up a flare. I have purchased both the MEFI 1-4 Scan and tune software and the MEFI 5 software. The latest MEFI software on the the thumb drive does notwork and does not have install instructions. I get an 8200 error dealing with the com port selection.
I have been going around and around with Ken and Bob from OBD Diagnostics. Ken sent me a link to a new software fix, it still doesn't work. Does anyone have an older version of the software instructions, or any knowledge how to designate the com port. Any help would be appreciated.
