I know there are different tactrix cable revisions which work with only certain model years so there might be more to it. Anybody?
The Subaru ECU requires very specific baud rates to flash. Colby found the cheapest chip he could that would do those rates. No one has found a USB->Serial converter that will as well, unless it used those chips.
