The explanation from EFILive was shared on Corvettes of Westchesters facebook page earlier this week. I'll share it here too.
EFILive would like to address our customers concerns who are asking why CoW has remote T87A programming abilities when we've said we will not be supporting that TCM with our software or hardware.
We have NOT developed T87A flashing ability for our software or hardware, the process is completely different to the regular T87 TCM therefore our existing T87 support will not work. All queries regarding the method employed should be directed to
Corvettes of Westchester and not EFILive.
We are not trying to rain on CoW's parade but merely point out this is not an EFILive developed 2017+ TCM tuning solution.
Cheers
Cindy
