I have two licenses for TC OBDII and I'm considering selling one. I purchased a copy of TCOBDII not too long after the software was released and the buyer will get the original installation disk. Updates can be obtained from TC. I will work with TC to ensure registration is transferred properly. The interface cable is not CAN compatible and IMO is not worth including. I bought the software with a definition for the black box C/K truck pcm that works from 96-99 and I purchased a second definition for an '09 Malibu with 3100. These could be included or omitted. I believe I paid $350 for the original package and $80 for the Malibu license. As I have no idea of the current value of the license, I am entertaining offers.
