I recently had to change PCM's in a 2006 Z06. I have updated my Flashscan and software to the latest version and revs. I continue to get the 06FF Checksum failure message after several attempts to flash the controller. I have attached tAttachment 18195he file I am using. Any help would be greatly appreciated. Thank you.
I have been able to perform a full flash of the controller with a different file. I have also been able to flash the PCM with the stock GM calibration file using my GM MDI interface. Looks like my attached file may be the issue. Any advice?
Looks like another programmer had been on there before, one of them does something to the tunes that makes EFILive think the checksums were wrong at the end of the flash, try the attached 'fixed' version of that tune.
Cheers,

Thank you for the reply.
Looks like my software version will not open the file. I am running 8.2.2.258 Build 258.
What version are you on?
I just downloaded the March update and was able to open it. I will give it a try and let you know.
Thanks
