I'm one of the lucky peeps that have been chosen to beta test Hypertech's programmer for the 2010 Camaro for the L99 Automatic Transmissions.
Hypertech programmers plug into the OBDII port .. so no ECU to flash and I believe this one is computer updateable via the web...

Mine is a 2SS/RS Auto with paddle shifters....
They're overnighting it to me and I should have it tomorrow morning sometimes.... I'll be reporting back.
Considering I was happy with my car, then found it needed the ECU reset (which I did today) and I was even MORE happy ... if that was possible.... having this programmer is probably give me perma-grin!
