hello and thanks to anyone that helps out!!.
i am trying to log my aem wide band that i hooked up to my rear 02 "the green connector". i have a log file for a 551m AEM WB that i have been trying to alter as i get a hardware fault when me7 logger tries to verify the hw numbers. now i am having a lil trouble understanding the relationship between the cfg, ecu, and bin file. i have tried editing the 551m aem .ecu file to alter the hw number but it still didnt change the outcome. any help or insight would be greatly appreciated.
i am assuming the gui looks for the same file as the .cfg in the ecu folder within the directory but i am kinda lost
