I bought an H&S Minimaxx tuner recently and it gives me an error code when I try to flash the truck with the tune. I know H&S is long out of business and that this probably isn’t a true Minimaxx but I was curious if anyone has had the same problem as me and if they were able to fix it. When I try to flash the tune, I get “Error code 0, unable to open file lmlt1.mmd”. I verified that the SD card was in the correct format and that the file was installed on the SD card. I even tried to reformat the SD card and reinstall the tune files but it still doesn’t work. Has anyone been able to work around this? I was refunded my money by my credit card company because the website I bought it from would not respond to me but if I could get this thing to work that would be pretty sweet.
