EFI Live Error message attached.

Sorry I've read both of your threads about a using a LS3/4L80 E38/T42 and am completely lost at what you are attempting to do. I see nothing in that pic about WinFlash OBD2.
Sorry about the confusion . . . my problem is EFI Live. Most times EFI Live will open a .bin file, but my EFI Live is not opening the Read T42 1GCGG25K791142143.bin.
It's a long shot, I was hoping someone would be willing to try opening Read T42 1GCGG25K791142143.bin with EFI Live.

I've never used EFI Live on Gen 4 stuff. Only Gen 3. When you read a ECM/TCM combination with EFI Live dies it create 2 separate files like TC OBD2 does or does it combine both controllers into one file like HP Tuners does?
This one can be opened. I added some extra data that is not used to match the chip size.
SLave must match main OS or you will get all kind of troubles.
Dave any chance you can use an ls3 oS upto 2011. After that there is a new code revision used, and will be much harder to figure stuff. It will be best if the t42 OS to be from the same year as ls3 OS.
Thank you!

Two separate files.

I'm wondering if the information in this gearhead-efi thread is accurate? The members who posted the information below are not active members. I'm thinking "ETC" is Electronic Throttle Control?

"Unless the E38 already has a 2009 Corvette calibration loaded, you can't flash in a 2009 Corvette *.cal and expect the ETC to be functional.
By example - if the E38 is from a truck / van / SUV, or is new from GM - it must have the 2009 Corvette calibration loaded with a Tech 2 first. Only a Tech 2 can load the ETC programming - no tuning software can read this portion of the ECM, as it is a "Write only" section - and therefore has nothing to write to this portion of the ECM."

"This can be a problem if you are switching applications with a particular ECM. There are 8 calibration modules in these calibrations. Modules 7 and 8 are used by a secondary microprocessor in the ECM and are not typically used in the calibration process. These modules are not read, modified or reprogrammed by the WinFlash OBDII program so the program will not allow you to program an ECM with a particular calibration file if the modules 7 & 8 associated with that calibration are different from the modules 7 & 8 that are currently stored in the ECM.
The GM system does reprogram modules 7 & 8 so you can change applications using that. SO what you'll need to do is reprogram the ECM with the stock calibration that you want to start with using the GM system. Then you'll be able to tune it with the OBDII Tuner program."
