LS1 Edit / HP Tuners Question
LS1 Edit / HP Tuners Question I own LS1 Edit for my car but would like to make some changes to a couple of tables that Edit doesn't address. I have access to HP tuners for a short time. If I make the changes to those tables with HP Tuners and flash with HP Tuners, will a later flash with Edit overwrite the changes with no problems?
Are the data files downloaded from the computer for Edit and Tuners the same exact data?

yes... if you overwrite w/a .ls1 file you read from the PCM prior to updating those tables, it will write them back as they were in that file
