I have an Enginer PHEV with BMS 16D version 3.3. I lost the SD card that came with the BMS (my fault!), and have been unable to get another SD card to work. Any attempt to use a new card results in the message "Log Error!" displaying when the BMS Monitor starts up. A few questions: - Is there any 'trick' to getting a standard SD card to work in this thing? I have used four standard 2GB SD cards, formatted FAT, and verified working in two computers. All fail in the same manner. Do they need special formatting, files, or need to be high-speed SD cards? - If you happen to have a BMS16DVer3.3 and can successfully get another SD card to work in your system, would you mind sending me your old one to see if it will work in mine? I'm willing to pay a reasonable/fair price for this service, even knowing that it may not work in my unit. If interested, PM me.
