I have 7.5.3 on home PC and 7.5.4 on laptop. Logged run on laptop and want to work with file on home PC and says need 7.5.4 to read. Do I have to install 7.5.4 on home PC for scan tool and tune tool? Do I just do the same beta update only with out the firmware update? Also set a check engine light twice and when checked with scan tool 7.5.4 and the most recent version of flashscan it said there were DTC's. Used flashscan to clear all DTC's and light went out so there must have been a code but it wouldn't tell me which one.
