Nemo, we've had reads sent in from some 2011 V6 Camaro's, so it should work without the badfileformat error. Though I think what is happening is you have read it with V8 then tried to open it in v7.5. This won't work, v7.5 has not been configured in any way to handle these Bosch V6 ECM's. The demand for tuning these you would think might be high, it just doesn't appear that way. The ability for EFILive to read the Bosch E77 & E69 ECM's has been out for over a year and I can't say that we've been flooded with files asking for support. I would suggest this might be why HPT quit working on them too.
If you get your hands on a 2012 V6 Camaro, different story, they switched to the E39 ECM which we do support.
